I have oily scalp.
<br>
My hair is oily, dandruffy, and it's covered with oil
<br>
I find scientific data on the Internet.
<br>
In my opinion, people with hair loss have oily skin, but which shampoo is not important
<br>
I think it would be better to use an oily shampoo but choose one that suits you.
<br>
And just wash it well after shampooing.
<br>
Then it doesn't matter.
<br>
Don't be misled by the shampoo commercial
<br>
It's the best if you buy a local oily shampoo and hang it well.
<br>
<br>
<br>
the right way to shampoo
<br>
<br>
<br>
<br>
Since shampooing is often the cause of various hair problems, it is necessary to check the habitual shampooing method.
<br>
<br>
In case of dry hair, if you shampoo every day, the shine disappears and it becomes bushy
<br>
<br>
2-3 times a week (it removes too much sebum from the scalp, causing dry hair or dandruff)
<br>
<br>
It can also be a cause.) is appropriate, and for oily hair, it's standard to use a styling agent every day
<br>
<br>
I can say it. It helps with blood circulation before shampooing and turns your fingers to make it easier to remove impurities
<br>
<br>
It's lightly massaged to stimulate the scalp, release tangled hair, and remove impurities
<br>
<br>
The most basic way to take care of your hair (usually to get the nutrients from your scalp to your hair)
<br>
<br>
It is appropriate to brush about 100 times.). With 36-38 degrees of lukewarm water, the entire scalp
<br>
<br>
Wet it, apply the right amount of shampoo according to the length of your hair and apply it evenly, so that the impurities get on the foam
<br>
<br>
Like you're massaging with your fingers, you're lathering your scalp and holding it lightly like it's bouncing
<br>
<br>
She massages her scalp. It's easy to break your hair by blowing it in water, so make it light so that it doesn't irritate you
<br>
<br>
After you dry it off, apply rinsing evenly from the tip of your head, and if it's too dry
<br>
<br>
If there is any damage, conditioner (rins are nourishing hair). therefore
<br>
<br>
If it's not oily hair that gets oily even if you wash it every day, conditioner
<br>
<br>
It's a good idea to use it. Especially on the tip of your hair, which is the most vulnerable
<br>
<br>
Use it like a massage.So that the rinsing ingredients don't touch the scalp
<br>
<br>
You have to be careful.In addition, it is most important to cleanse the conditioner. I didn't wash my hair
<br>
<br>
The remaining rinsing ingredients are dandruff. It can cause hair loss.) After applying a lot of it, slightly apply it in water at 40 degrees
<br>
<br>
Soaking softens your hair. After rinsing in lukewarm water, when it's wet
<br>
<br>
If you dry your hair, it will damage your hair, so just brush it off with your fingers
<br>
<br>
First, remove the moisture, then insert the hair between the towels and pat it to remove the moisture.
<br>
<br>
When it is dry, hot wind is easy for the constituents of street hair to destroy proteins. Wet
<br>
<br>
It's like using hot air while you're in a state that double damages your hair.First, let's dry the hair
<br>
<br>
Remove completely and make sure to keep at least 20cm distance from the dryer.
<br>
<br>
At the end, you can fix your hair style for a long time by finishing the drying with cold wind.
<br>
<br>
Treatment or pack products actively supply the lack of protein or oil in the head
<br>
<br>
It plays a role. Rinsing makes your hair soft by coating the surface of your hair thin
<br>
<br>
That's why it's good to apply facial masks evenly to your hair and scalp
<br>
<br>
It's better to use it mainly for hair. If you don't have problems with your hair condition with just conditioning
<br>
<br>
No special hair care is required. If it's too dry, I'll use a treatment together
<br>
<br>
use.

<br>
scalp massage
<br>
<br>
<br>
<br>
In order to keep your hair healthy and shiny, the scalp
<br>
<br>
The health of is important. So, make sure you don't get regular and consistent scalp massages
<br>
<br>
Maintaining the healthy scalp through is a good way for beautiful hair
<br>
<br>
It can be said to be the first step. The scalp is a normal scalp, dry scalp, and oily scalp
<br>
<br>
Since it is distinguished, each person should be groomed according to the nature of the scalp.
<br>
<br>
1) Normal scalp - Normal, covered with a moderate layer of fat
<br>
<br>
It refers to a healthy scalp that has cognitive effects. These scalp are normal
<br>
<br>
You can use a hair pack to trim the normal scalp.
<br>
<br>
2) Dry scalp - insufficient sebum secretion in scalp. dry scalp
<br>
<br>
Trim using conditioner or oil.
<br>
<br>
3) Oily scalp - a condition in which the sebum in the scalp is excessively secreted and oily
<br>
<br>
C. Use a non-irritating lotion for oily scalp to massage the scalp
<br>
<br>
Let's make it happen.
<br>
<br>

<br>
about dandruff
<br>
<br>
<br>
<br>
Dandruff. Itchy. Dandruff is a phenomenon where the dead skin on the scalp comes off and dries
<br>
<br>
I have to be vigilant to be the target. Isn't the dandruff-stacked collar messy and terrible just to think about it!
<br>
<br>
<br>
<br>
▶ Dandruff has dry dandruff and oily dandruff.
<br>
<br>
Dry dandruff is a phenomenon in which keratinocytes flutter and fall white as the scalp dries due to lack of sweat or sebum in the sebaceous glands.
<br>
<br>
Use hair oils or oily treatment agents to replenish oil and prevent drying.
<br>
<br>
Oily dandruff produces too much sebum, which makes your scalp fat and dead skin cells and oil
<br>
<br>
Cleanliness is the most important care method as it clumps together and falls wet. hot
<br>
<br>
Water or wind also promotes the oil rate of the scalp, so avoid it.
<br>
<br>
<br>
<br>
▶ The cause of itching is the dirt of the scalp and the reproduction of germs, so always keep your head
<br>
<br>
It is important to keep it clean. Before shampooing, brush your hair to remove impurities
<br>
<br>
Massage the scalp with the tip of your finger to promote blood circulation. Even after washing my hair
<br>
<br>
If you feel itchy, the scalp dirt is not completely removed or rinsed thoroughly
<br>
<br>
Because I didn't.
<br>
<br>
<br>
<br>
- a dandruff prescription-
<br>
<br>
<br>
<br>
1) Aloe Massage - Aloe juice is very effective for dandruff or scalp itching. The outer skin of aloe
<br>
<br>
When you cut it out, you get sticky mucus inside. Apply mucus on a cotton pad and massage the scalp evenly.
<br>
<br>
Wash thoroughly after 10 minutes.
<br>
<br>
<br>
<br>
2) Green tea massage - effective for seborrheic dandruff and hair loss. If you don't have green tea leaves, I'll have green tea bags
<br>
<br>
You can use the eraser. Pour 1 cup of water into 1 tablespoon of green tea and boil until the amount is halved.
<br>
<br>
Massage hair and scalp evenly by applying juice to cotton or cotton pads. on a daily basis
<br>
<br>
If you do it, the dandruff disappears.
<br>
<br>
<br>
<br>
3) Cheongju Massage - Excellent for relieving dandruff and itching. After washing my hair, about half a cup
<br>
<br>
Pour rice wine all over your head. Massage like gently rubbing the scalp. with lukewarm water
<br>
<br>
rinse lightly.
<br>
<br>
<br>
<br>
4) Milk massage - moisturizes the scalp to calm dead skin cells and excess sebum
<br>
<br>
It removes it. Heat 1/2 cup of milk to a lukewarm temperature. I put it on a cotton pad and dabbed my hair
<br>
<br>
I give you a massage. Massage the entire scalp and leave for about 10 minutes, then wash thoroughly
<br>
<br>
<br>
<br>
. 5) Bamboo salt massage - Effective for dandruffy hair due to high oiliness. Shampoo
<br>
<br>
Afterwards, spray about a spoonful of bamboo salt on the head while wet. When the bamboo salt melts, soften the scalp
<br>
<br>
I give you a massage. After rinsing with warm water, rinse again with cold water to tighten the scalp
<br>
<br>
<br>
<br>
<br>
<br>
Brushing
<br>
<br>
<br>
Brushing stimulates the scalp to smooth the blood flow and to the hair
<br>
<br>
It removes dust and dandruff from your hair, so it's healthy and beautiful
<br>
<br>
play a nurturing role. When you brush your hair, the brush will touch your scalp
<br>
<br>
You have to brush it in deep enough so that it can work properly.
<br>
<br>
I'm going to use a cushion brush that doesn't irritate the tip
<br>
<br>
It is recommended to conduct it 50-60 times.
<br>
<br>
For the brushing order, brush the ends of your hair or the tangled parts first
<br>
<br>
It is brushed from the back of the ear toward the back of the neck. Lastly
<br>
<br>
Lower your head and brush it forward from the nape of your neck. a person who suffers from hair loss
<br>
<br>
If you have one, you brush your hair properly because it's going to lose it
<br>
<br>
There are cases where you don't use it well, but if you neglect brushing
<br>
<br>
It may lose elasticity and fall out better. Therefore, there is hair loss
<br>
<br>
People also use a proper brush for scalp health and hair strengthening
<br>
<br>
It's good to give.
<br>
<br>
<br>
hair massages

<br>
<br>
■ Rinse with fresh lemon
<br>
<br>
Rinse with water diluted by cutting half a lemon into 1ℓ of water and mixing the juice. It is good for both oily and dry hair.
<br>
<br>
■ Vinegar Linx, which is good for oily hair
<br>
<br>
Mix 1 liter of water with 2 small servings of apple vinegar or fruit vinegar and use it to rinse the head. It is better for oily hair than dry hair.
<br>
<br>
■ beer good for damaged hair
<br>
<br>
Beer is widely known as a simple dye. But beer is damaged
<br>
<br>
It is also useful to make your hair shiny. First, the head
<br>
<br>
After shampooing, dry your hair a little bit and apply 100cc
<br>
<br>
Apply beer evenly to the hair and wait for about 15 minutes. Let's go back to the water
<br>
<br>
After rinsing, remove the water with a towel and apply the remaining beer again
<br>
<br>
Dry with a thick comb while combing gently.

hair physiology
<br>
<br>
<br>
1. the process of hair formation
<br>
<br>
① Meals: Protein sources (beef, pork, beans, fish, etc.)
<br>
<br>
② Digestion: Proteins are broken down into amino acids by enzymes.
<br>
<br>
③ Move: Amino acids are transported through the blood vessels to each part of the body, and the hair and
<br>
<br>
It is a raw material for making skin, etc.
<br>
<br>
<br>
<br>
2. composition of hair
<br>
<br>
<br>
<br>
Many of the chemical compositions that originate from atoms are elastic
<br>
<br>
Various kinds of hair, including intensity, extension, etc
<br>
<br>
In order to impart physical and chemical properties, it has organized and complex chemical bonds.
<br>
<br>
When it comes to hair chemical bonding, as we've seen before, it eventually forms hair
<br>
<br>
The bonds between the chemical components are the basis. the basic structure of hair
<br>
<br>
If you look at it, it's three long strands of keratin that look like woven fabric
<br>
<br>
The protein is bound and tightly twisted. As mentioned earlier, vertically
<br>
<br>
The binding consists of the binding of the mode polypeptide
<br>
<br>
It is usually referred to as the main 鎖結 bond. with each of the adjacent main chains
<br>
<br>
The side chains (the part of R in the structure of amino acids) also bind together
<br>
<br>
There is, but this is called a 側鎖結 bond because it is connected horizontally.
<br>
<br>
1) Main chain binding (vertical binding): to form the main chain of keratin proteins
<br>
<br>
Hundreds to thousands of amino acids come together to form polypeptide bonds
<br>
<br>
It's stronger than the side chain bond, so the hair is horizontal
<br>
<br>
It breaks more easily vertically.
<br>
<br>
2) Side chain bonds (transverse bonds): The keratin in hair is applied to the following three types of side chain bonds
<br>
<br>
Since it is firmly connected by, it has a very strong structure and elasticity mechanically.
<br>
<br>
① Cystine bond: one of the characteristics of keratin proteins
<br>
<br>
is that it contains a lot of cystine. between Systine's sulfur (S)
<br>
<br>
Binding is the strongest of side chain bonds, so you have to deal with chemicals (reducing agents)
<br>
<br>
The permanent wave process is the beauty technique using this principle
<br>
<br>
◐ Note: Two cysteine amino acids come together and cysteine
<br>
<br>
It becomes (cystine) amino acid and contains a relatively large amount of sulfur (S), so S-S bond
<br>
<br>
It's also called this.
<br>
<br>
②Ion (salt) bond: amino groups between adjacent main chains
<br>
<br>
(NH₂+) and carboxyl group (COOH-) are electrostatically bonded
<br>
<br>
When there is no potential difference of, it combines most strongly. In other words, hair is an isoelectric point
<br>
<br>
In the state, the ionic bond is strong, and in the strong acid or strong alkali state, the bonding force weakens.
<br>
<br>
③ Hydrogen bond: It is double bonded to carbon in the main chain
<br>
<br>
Oxygen is bonded to hydrogen, which is bonded to nitrogen in the other main chain
<br>
<br>
One hydrogen bond is weak, but among the side chain bonds, the hydrogen bond is weak
<br>
<br>
Since it is the most present, it can change hair in various ways.
<br>
<br>
This bond is easily broken by water, so a temporary set is possible.
<br>
<br>
④ Peptide bond: Amino acids such as glutamic acid and lysine
<br>
<br>
The amino group and carboxyl group in the silver side chain link peptide bonds to each other.
<br>
<br>
<br>
<br>
3. the structure of hair
<br>
<br>
1)Structure and Name of Hair Roots and Hair Organs
<br>
<br>
<br>
<br>
① Hair roots (the area of hair in the skin): follicles, hair masses,
<br>
<br>
, Papilla, mother cells, my.a root plant of outer beauty
<br>
<br>
(inner.outer root sheath), 피지선(sebaceous gland), 입모근(arrector pili muscle)
<br>
<br>
②Hair liver part (the area of the hair outside the skin): hair cuticle, hair cortex
<br>
<br>
(cortex), medulla
<br>
<br>
* Fur cortex = fibrillation + interference substance (matrix)
<br>
<br>
2) Comparison of Properties of Textiles and Insects
<br>
<br>
fibril
<br>
<br>
1. macrofibril, microfibril,
<br>
<br>
It consists of protofibril, polypeptide (PPT), and amino acid molecules in order.
<br>
<br>
2. It consists of 結晶 keratin.
<br>
<br>
3. The cystine content is less than that of the insecticide.
<br>
<br>
an insecticide (matrix)
<br>
<br>
1. It serves to fill the fiber.
<br>
<br>
2. It has a natural moisturizing factor (NMF), so it contains almost all of the moisture in the hair
<br>
<br>
be held in (dry hair when the insecticide is lost).
<br>
<br>
3. It consists of 情型 keratin (also known as C-keratin).
<br>
<br>
4. Cystine content is higher than fiber.
<br>
<br>
<br>
<br>
3)Comparison of the properties of hair and insecticide
<br>
<br>
Cuticle
<br>
<br>
1. About 15% of the hair
<br>
<br>
2. There is no melanin pigment.
<br>
<br>
3. Lipophilic (親油) and 撥 (water repellency)
<br>
<br>
4. be vulnerable to physical friction.
<br>
<br>
an insecticide (matrix)
<br>
<br>
1. About 50% of the entire hair
<br>
<br>
2. There is a lot of melanin pigment.
<br>
<br>
3. Hydrophilic (親)
<br>
<br>
4. It is easy to receive the action of drugs such as cold liquid.
<br>
<br>
<br>
<br>
4. Hair growth cycle
<br>
<br>
1) the cycle of hair
<br>
<br>
- A hair is born and grows well. It stops when it's sissy
<br>
<br>
The time until you lose and you have new hair there again
<br>
<br>
<br>
<br>
(1) Growth or anagen
<br>
<br>
- The best time to grow when momocyte division is active
<br>
<br>
- At this time, hair grows by 0.35 to 0.4 mm per day
<br>
<br>
- Growth of 10.5mm to 12mm in one month (0.35mm × 30 days ~ 0.4mm × 30 days)
<br>
<br>
- If we assume a six-year lifespan, we're going to have a six-year lifespan, and we're going to have a six-year lifespan
<br>
<br>
The length is (0.35 mm × 365 days × 6 years to 0.4 mm × 365 days × 6 years) 76.6 cm to 87.6 cm
<br>
<br>
- Female growth period: 4 to 6 years, male: 3 to 5 years
<br>
<br>
(2) Degeneration or catagen
<br>
<br>
- A time when the division of the mother cells that have passed the growth period is gradually decreasing
<br>
<br>
- It usually takes one to two months
<br>
<br>
(3) Telogen
<br>
<br>
- a time when division comes to a complete halt
<br>
<br>
- After a certain amount of time, I'll naturally fall out and start again
<br>
<br>
In the same hair follicle, new hair is preparing to continue for generations
<br>
<br>
∵ Two forms of hair cycle
<br>
<br>
(1) Synchronic type
<br>
<br>
- The hair cycle is like a mode, so it falls out at the same time
<br>
<br>
- It is mainly seen in animal molting.
<br>
<br>
(2) Mosaic type
<br>
<br>
- Your hair has its own hair cycle, so some hair falls out
<br>
<br>
And some hair is growing newly, so the overall number of hair
<br>
<br>
if there is no significant change in
<br>
<br>
- a person's hair cycle
<br>
<br>
<br>
<br>
5. Physiological Characteristics of Hair
<br>
<br>
<br>
<br>
1) the color of one's hair
<br>
<br>
The color of hair is formed from an amino acid called tyrosine
<br>
<br>
Melanin is determined by the pigment melanin, which is melanocyte
<br>
<br>
It is secreted by cells called melanocyte
<br>
<br>
Melanins are eumelanin, which is black brown, and yellow red
<br>
<br>
It is divided into two types of phaemelanin.
<br>
<br>
2) hair and hormones
<br>
<br>
- Female Hormones: Promote Hair Growth (Extended Activity)
<br>
<br>
- Male hormones: Promote body hair growth and sebum secretion (suppressing hair activity)
<br>
<br>
- Also Read: Male Hormones Secured From Testiculars: Boosting Beard, Fleece Growth
<br>
<br>
Male hormones secreted from the adrenal cortex: arms, leg hair, and the growth of the Virgin Mary
<br>
<br>
- Hormones related to hair: growth hormone, thyroid hormone, adrenal cortex
<br>
<br>
Hormones, gonadotropic hormones, etc
<br>
<br>
3) natural hair loss
<br>
<br>
- A phenomenon in which hair that has stopped growing naturally falls out according to the hair growth cycle
<br>
<br>
- The difference between abnormal hair loss and hair loss is the number of hair loss during a day and hair loss
<br>
<br>
Separated by the shape of
<br>
<br>
- Person A has a four-year hair cycle and has about 100,000 hairs
<br>
<br>
Assuming that, 100,000 ÷ 365 days × 4 years + about 68 daily natural hair loss
<br>
<br>
- There are personal differences, but more than 100 to 200 drawings fall out a day
<br>
<br>
suspected hair loss
<br>
<br>
- The shape of the natural hair loss muscle is round like a club, but in the case of abnormal hair loss, the end is deformed
<br>
<br>
- As you get older, your growth period gets shorter, so if your hair cycle gets shorter, it's a day
<br>
<br>
Increased number of hair loss
<br>
<br>
- Natural hair loss occurs most often in the fall season because of summer
<br>
<br>
It's low in nutrition during the season, and the scalp is dirty with sweat and fat secretions
<br>
<br>
It is believed that this is because it affects the hair roots and the rest period becomes faster, and the symptoms appear in autumn.
<br>
<br>
4) Hair elongation rate: hair in the active phase grows about 1.2cm per month.
<br>
<br>
5) Hair section (shape and thickness)
<br>
<br>
- Capricorn index: Minimal when the hair is cut in a round shape and the diameter of the cut is measured
<br>
<br>
Number multiplied by 100 by dividing the diameter by the maximum diameter
<br>
<br>
- The larger the capillary index, the round straight hair, and the smaller the elliptical axial hair
<br>
<br>
- Asian people's maternal index is 75-85, white 62-72, and black 50-60
<br>
<br>
- Thickness of hair: Usually 0.07~0.08mm and only 0.05mm
<br>
<br>
There are thin hair, and on the contrary, there are thick hair of about 0.15mm.
<br>
<br>
There are many personal differences.
<br>
<br>
<br>
<br>
6. the physical properties of hair
<br>
<br>
1)Hair elongation (%) and elasticity
<br>
<br>
- phenomenon caused by the structural properties of keratin proteins
<br>
<br>
- Hair elongation is affected by humidity.
<br>
<br>
- Usually, the growth rate that can be returned to the original length at room temperature is around 5%
<br>
<br>
- Hair can be stretched from 50% (0.5x) to 70% (with moisture absorption) when pulled
<br>
<br>
2) Hair fixation (power required to pull out a single hair, g)
<br>
<br>
- Hair does not fall out easily because the hair follicle and hair bulb are in close contact with the pore wall.
<br>
<br>
- Depending on the hair cycle, it is strong during the growing season and weak during the degeneration period.
<br>
<br>
- Most hair that falls out during shampooing is the hair that's in the late fuge period
<br>
<br>
- Power required to pull out hair in the growing season: 50 to 80g
<br>
<br>
If the total number of hair is 100,000, 100,000 x 50g = 5 tons, that is, the whole hair
<br>
<br>
It takes 5 tons of power to pull it out at the same time
<br>
<br>
3) Absorbability of hair (hygroscopic, %)
<br>
<br>
- Hair absorbs moisture because of the hydrophilicity of keratin proteins
<br>
<br>
- Moisture penetrating into the hair is a capillary-like void (孔) between the hair fibers
<br>
<br>
Adsorbed to the wall of
<br>
<br>
- In the case of healthy hair, hair loss contains about 30% moisture immediately afterwards
<br>
<br>
- Healthy hair moisture content is usually 8-12%
<br>
<br>
- It is affected by humidity in the air and the degree of hair damage
<br>
<br>
4) hair swelling
<br>
<br>
- If you soak a dry sponge in water, it will absorb moisture and soften
<br>
<br>
At the same time, as the volume increases, the hair absorbs liquid and increases its volume
<br>
<br>
- Soaking hair in water is 1-2% long, 15% diameter, 30% weight due to swelling
<br>
<br>
(weight of moisture) Degree of increase (diameter change is greater than length change)
<br>
<br>
- When hard hair is inflated, the protein in the hair becomes like a mesh
<br>
<br>
It's because the penetrated moisture enters the network and pushes it wide
<br>
<br>
- It's because of the chemical combination of hair and the force that inflates by moisture
<br>
<br>
When the force is equalized, the swelling becomes average, which is called finite swelling
<br>
<br>
- When keratin is treated with strong acid or strong alkali, it eventually dissolves, and this is infinite
<br>
<br>
It's called swelling
<br>
<br>
- Damaged hairs with reduced side chain bonds easily swell due to increased absorption
<br>
<br>
- Hair behavior is proportional to temperature and varies depending on the ph of the solution being treated (isoelectric point)
<br>
<br>
low in, high in acidity and alkalinity)
<br>
<br>
<br>
<br>
5) heat, light denaturation
<br>
<br>
- Because hair is a protein, its color and structure are changed by high heat or light
<br>
<br>
- Depends on the presence or absence of moisture when hair is denatured by heat or light
<br>
<br>
- Dry condition: 120℃ → swelling, 130~150℃ → discoloration and reduction of cystine,
<br>
<br>
180℃ → Deformation of keratin structure, 270~300℃ → decomposed by burning
<br>
<br>
- High humidity conditions: 100℃ → reduction of cystine, 130℃ → deformation of keratin structure
<br>
<br>
- In high humidity conditions, damage is easy even at relatively low temperatures
<br>
<br>
- I don't wash my hair with chemicals or shampoo well, so the detergent
<br>
<br>
When left, heat is applied to promote denaturation
<br>
<br>
- Infrared and UV rays cause thermal degeneration of hair
<br>
<br>
- Be aware that the hair of coastal residents and people who play intense outdoor sports is thermally denatured
<br>
<br>
<br>
<br>
7. Chemical properties of hair
<br>
<br>
<br>
<br>
1) hair and pH
<br>
<br>
The pH is the concentration of hydrogen ions (H?) in a solution
<br>
<br>
It refers to pH 7 as neutral depending on the concentration, and below that, acidity
<br>
<br>
The above is said to be alkaline.
<br>
<br>
2) Mountain and hair
<br>
<br>
- Hair is quite resistant to chemical irritation, especially acid
<br>
<br>
- Protein, a component of hair, tightens when it comes to acid
<br>
<br>
When the hair is treated with acid, the hair surface is closed to prevent the acid from entering the hair
<br>
<br>
- Hair with normal hair pigmentation is not damaged unless strong acid is used
<br>
<br>
- Even if your hair is slightly damaged, it's much less compared to alkali-induced irritation
<br>
<br>
3) Alkali and hair
<br>
<br>
- Isoelectric point of hair: range of pH 4.5-5.5 in the most stable state of hair
<br>
<br>
- The hair is treated with an alkaline agent, and the further away you go from the isoelectric point, the more amino you are
<br>
<br>
Weakness of acid causes hair to become weak
<br>
<br>
- Especially strong alkalis break down proteins themselves as well as side chain bonds
<br>
<br>
<br>
<br>
8. Principles of Permanent Wave
<br>
<br>
- Amino acids that make up the hair are connected by several chemical bonds
<br>
<br>
- Chemical bonds required when amino acids are connected vertically: peptide bonds
<br>
<br>
- Chemical bonds required when amino acids are linked horizontally: peptide bonds, cystine
<br>
<br>
bonding, salt (ion) bonding, hydrogen bonding
<br>
<br>
- Weak bonds: hydrogen bonds, salt bonds
<br>
<br>
- Strong binding: peptide bond, cystine bond
<br>
<br>
- Permnant wave agents are responsible for breaking the cystine bond of transverse bonds
<br>
<br>
- Principle of permant wave:
<br>
<br>
* Reduction reaction of the first solution: If the hair is treated with 1 solution high in hydrogen (H)
<br>
<br>
Hydrogen enters between cystine bonds, i.e. -S-S-S- and reduces it to the -SH HS- equation
<br>
<br>
The bond is easily broken.
<br>
<br>
(Thioglycolate and cysteine are used as reductants for the first solution)
<br>
<br>
* Oxidation reaction of the second solution: to recombine broken cystine bonds
<br>
<br>
When oxygen (O) is supplied, hydrogen is combined with oxygen, so it becomes -S-S- again.
<br>
<br>
(Sodium bromide (NaBrO3) high in oxygen is mainly used for oxidizing agent in the second solution
<br>

■ Sonia Yoon's column: Does oil flow if I turn around even if I shampoo every day?
<br>
<br>
<br>
It's as if you're not shampooing your oily hair, and it smells too much
<br>
It smells bad!
<br>
This is not a common concern.
<br>
However, many people are suffering from oily scalp.
<br>
There are many reasons for oily scalp,
<br>
our bodies lack energy and hormones due to lack of vitamins and diet
<br>
I'm going to have a problem. At this time, cell division becomes difficult because nutrients are not properly supplied, and hair circulates by hair cycle.
<br>
<br>
During the circulation process, the hair is dry and the sebaceous glands that create a protective layer on the scalp
<br>
It produces a lot of sebum.
<br>
In the process, many sebums accept new fungi,
<br>
This leads to severe odors and dry hair, seborrheic hair loss, scalp purification, and so on.
<br>
<br>
To prevent this, you need shampoo and teaknick that fit your feet.
<br>
I use oily shampoo and shampoo as if I'm drinking it gently,
<br>
The last rinse should be rinsed with water that feels a little cold.
<br>
<br>
For oily shampoos, buy professional hairshops or sterilizing shampoos on the market,
<br>
Products that are too focused on sterilization will dry out your hair,
<br>
You have to choose carefully.
<br>
<br>
Oh, my!
<br>
Shampooing is recommended in the evening.
<br>
The morning shampoo is alive, but the outside pollution is still in your hair,
<br>
If you sleep in that state, your scalp and your hair can't breathe,
<br>
When our body is resting, the scalp works hard to cause cell division,
<br>
Because it's an important time to accumulate living energy the next day,
<br>
I shampoo at night,
<br>
I sleep after drying it, and in the morning, I just put water on it and clean it up..
<br>
So please make healthy hair and scalp..
<br>

Everything About Shampoo for Healthy Hair
<br>
<br>
What is shampoo?
<br>
Shampoo is derived from the Hindi word "Champo", meaning "to massage" and "to press".
<br>
Shampoo not only removes dirt, dirt and oil from scalp and hair, styling products, but also scalp and
<br>
The purpose is to observe the hair condition and keep it healthy.
<br>
<br>
<br>
Shampoo, you have to use it like this!
<br>
It is important to know the right shampoo for you and the right number of times.
<br>
People who get a lot of sebum after shampooing have oily hair
<br>
It's good to do it every day, and it makes your hair dry and dandruffy
<br>
People wash them every other day with dry hair shampoo.
<br>
And on average, about three times a week is appropriate.
<br>
<br>
<br>
1. After brushing sufficiently, soak the hair in lukewarm water of about 38℃.
<br>
2. Squeeze out only the amount about the size of a 500 won coin, make enough foam, and rub it evenly all over your head.
<br>
People with intelligent hair should rub the bangs more carefully than the back of their hair to remove excess sebum
<br>
It can prevent hair loss.
<br>
3. When rubbing shampoo, do not use your fingernails, but rub lightly with your fingertips.
<br>
4. Wash cleanly with running water several times so that there is no foam left. If the foam isn't rinsed enough, the hair
<br>
Rinse thoroughly because it may cause hair loss as well as dryness.
<br>
<br>
<br>
Shampoo, let's not forget this!
<br>
choose the right shampoo for one's hair condition
<br>
dry hair
<br>
Shampoo with weak cleaning power is good for dry hair, and shampoo is good every other day. My hair
<br>
If damaged, it is easy to dry out, so it is also recommended to use damaged hair products.
<br>
<br>
<br>
oily hair
<br>
It is recommended to rinse oily hair with warm water to remove sebum while using a shampoo that has a strong cleaning power. Also, it is recommended to rinse it with warm water to remove sebum
<br>
In the case of oily skin, seborrheic dermatitis or oily dandruff occurs easily, but if you have oily dandruff, use dandruff shampoo
<br>
Use it, and in the case of severe dandruff, it is recommended to use medicinal sampu exclusively for dandruff about once a week.
<br>
<br>
<br>
Wet hair is perishable.
<br>
1. When the hair is wet, the hair is weak, so combing is likely to cause hair damage.
<br>
2. Wiping moisture with a towel also takes away moisture from the hair and causes it to lose its flexibility
<br>
Gently squeeze the water out with your fingertips, then wipe it off as if you were pressing it with a towel.
<br>
<br>
<br>
<br>
Checkpoint for choosing a good shampoo
<br>
Choose one that has adequate cleaning power, bubbles well, and fizz well.
<br>
Choose one that has less irritation to the skin or eyes.
<br>
The hair should be combed well without getting tangled after three feet.
<br>
There should be a certain amount of shine and flexibility without rinsing.

Messy dandruff... Hello!!
<br>
<br>
Dandruff is a phenomenon in which aging dead skin cells on the scalp are peeled off and fall off. dandruff falls white on one's shoulders
<br>
There are dandruffs of dry scalp and dandruffs of oily scalp that are sticky and yellow.
<br>
Let's find out the causes and grooming methods of dry dandruff and oily dandruff.
<br>
<br>
<br>
dry dandruff
<br>
Cause
<br>
It occurs when the sebum on the scalp is excessively removed by using frequent shampoos or shampoo with strong cleaning power, or when the shampoo remains in the head and irritates the scalp. As the scalp dries, the keratinocytes crumble and fall white
<br>
The form is called dry dandruff.
<br>
<br>
<br>
How to trim it
<br>
1. Change shampoo to dry (minor acidic) and wash your hair about every three days.
<br>
2. Apply hair cream or hair oil to the scalp before and after shampooing to replenish moisture and oil.
<br>
3. Wrap the head with a steam towel and leave it for about 20 minutes to prevent the scalp from drying out.
<br>
4. After that, shampoo with dandruff shampoo and rinse with lukewarm water.
<br>
5. Eat enough foods that contain a lot of vitamin A and animal protein.
<br>
<br>
<br>
an oily dandruff
<br>
Cause
<br>
The sebum, an oily substance secreted by the sebaceous glands, and the sweat secreted by the glands are both excessively secreted, so the scalp
<br>
Oily dandruff is when keratinocytes and oil clump together and fall off damply as they become fatty.
<br>
<br>
<br>
How to trim it
<br>
1. I use oily shampoo and wash my hair every day.
<br>
2. Use dandruff-only shampoo twice a week.
<br>
3. After shampooing, rinse only at the tip of the hair, avoiding the scalp.
<br>
4. Hot dryer winds promote oil production on the scalp, so keep it out of contact with the scalp.
<br>
5. Food intake consumes a lot of vitamins B2 and B6, which have the effect of inhibiting sebum secretion.
