> - Male hormones: Promote the growth of body hair and sebum secretion (suppression of hair activity)
 
>
 
> - Note: Male hormones secreted from testicles: Promote growth of beard and breast hair
 
>
 
> Male hormones secreted from the adrenal cortex: Promote arm, leg hair, and growth of the Virgin Mary
 
>
 
> - Hormones related to hair: growth hormone, thyroid hormone, adrenal cortex
 
>
 
> Hormones, gonadotropic hormones, etc
 
>
 
>3) Natural hair loss
 
>
 
> - A natural loss of hair that has stopped growing according to the hair growth cycle
 
>
 
> - The difference between abnormal hair loss and hair loss is the number of hair loss during a day and hair loss

> - Person A has a hair cycle of 4 years and has about 100,000 hairs

Assuming >, 100,000 ÷ 365 days × 4 years + about 68 daily natural hair loss
 
>
 
> - There are personal differences, but more than 100 to 200 drawings fall out a day
 
>
 
> Suspected hair loss
 
>
 
> - The natural hair loss muscle has a round end like a club, but in the case of abnormal hair loss, the end is deformed
 
>
 
> - As you get older, your growth period gets shorter, so if your hair cycle gets shorter, it's a day
 
>
 
> The number of hair loss increases
 
>
 
> - Natural hair loss occurs the most in the fall seasonally because of summer
 
>
 
> Due to poor nutrition during the season and the scalp is dirty with sweat and fat secretions
 
>
 
> This is because it affects the hair roots and the resting period becomes faster, and the symptoms appear in autumn.
 
>
 
>4) Hair elongation rate: Hair in the active phase grows about 1.2cm per month.
 
>
 
>5) Hair section (shape and thickness)
 
>
 
> - Capricorn index: At least when cutting hair round and measuring the diameter of the cut
 
>
 
> The number multiplied by 100 by dividing the diameter by the maximum diameter
 
>
 
> - The larger the capillary index, the round straight hair, and the smaller the capillary index, the oval axial hair
 
>
 
> - Asian people's maternal index is 75-85, white 62-72, black 50-60
 
>
 
> - Thickness of hair: Usually 0.07~0.08mm and only 0.05mm
 
>
 
> There are thin hair, and on the contrary, there are thick hair of about 0.15mm.

> 6. Physical properties of hair
 
>
 
>1) Height and elasticity of hair
 
>
 
> - A phenomenon caused by the structural characteristics of keratin proteins
 
>
 
> - Hair elongation is affected by humidity.
 
>
 
> - Usually, the rate of return from room temperature to normal length is around 5%
 
>
 
> - Hair can be stretched up to 50% (0.5 times) to 70% (when moisture is absorbed) when pulled
 
>
 
>2) Hair fixation (power required to pull out a hair in a single year, g)
 
>
 
> - Hair doesn't come out easily because hair is in close contact with the pore wall.
 
>
 
> - Depending on the hair cycle, it is strong during the growth period and weak during the deterioration period.
 
>
 
> - Most hair that falls out during shampooing is the hair in the late fuge period
 
>
 
> - Power required to pull out the hair of a single hair in the growing season: 50~80g
 
>
 
> If the total number of hair is 100,000, 100,000 x 50g = 5 tons, that is, the whole hair
 
>
 
> It takes 5 tons of power to pull it out at the same time
 
>
 
>3) Absorbability of hair (hygroscopic, %)
 
>
 
> - Hair absorbs moisture because of the hydrophilicity of keratin protein

Adsorbed to the wall of >
 
>
 
> - In the case of healthy hair, hair washing contains about 30% moisture immediately afterwards
 
>
 
> - Healthy hair moisture content is usually 8-12%
 
>
 
> - It is affected by humidity in the air and the degree of hair damage
 
>
 
>4) Hair swelling
 
>
 
> - If you soak a dry sponge in water, it will absorb moisture and soften
 
>
 
> At the same time, just as the volume increases, the hair absorbs liquid and increases the volume
 
>
 
> - If you soak your hair in water, it's 1-2% long, 15% diameter, 30% weight due to swelling
 
>
 
> (Weight of moisture) Increase in degree (the change in diameter is greater than the change in length)
 
>
 
> - When firm hair is inflated, the protein in the hair becomes like a mesh

> 5) Deformation by heat and light
 
>
 
> - Because hair is a protein, its color and structure are changed by high heat or light
 
>
 
> - Depends on the presence or absence of moisture when hair is denatured by heat or light
 
>
 
> - Dry condition: 120℃ → swelling, 130-150℃ → discoloration and cystine reduction,
 
>
 
> 180℃ → Deformation of keratin structure, 270~300℃ → It is decomposed by burning
 
>
 
> - High humidity: 100℃ → Cystine reduction, 130℃ → Deformation of keratin structure
 
>
 
> - Damage is easy even at relatively low temperatures under high humidity conditions
 
>
 
> - Because there are chemicals on your hair or you don't wash it well when shampooing, detergent
 
>
 
> When heat is applied while remaining, it promotes denaturation
 
>
 
> - Infrared and UV rays cause thermal deformation of hair

>
 
>1) Hair and pH
 
>
 
> pH is the concentration of hydrogen ions (H?) in a solution
 
>
 
> refers to pH 7 as neutral depending on the concentration, and below that is acidic
 
>
 
> The above is called alkaline.
 
>
 
>2) Acid and hair
 
>
 
> - Hair is quite resistant to chemical irritation, especially acid
 
>
 
> - Protein, a component of hair, tightens when it comes to acid
 
>
 
> When the hair is treated with acid, the hair pigmentation is closed to prevent the acid from entering the hair
 
>
 
> - Hair with normal hair pigmentation is not damaged unless strong acid is used
 
>
 
> - Even if the hair is slightly damaged, it is much less compared to alkali-induced irritation
 
>
 
>3) Alkali and hair
 
>
 
> - Isoelectric point of hair: pH 4.5-5.5 in the most stable state of hair
 
>
 
> - The further away you go from the isoelectric point, the more alkaline your hair is treated, the more amino you are
 
>
 
> Acid bonds become weak and hair becomes weak
 
>
 
> - Especially strong alkali breaks down the protein itself as well as the side chain bond
 
>
 
>
 
>
 
>8. Principle of permanent wave
 
>
 
> - Amino acids that make up the hair are connected by several chemical bonds
 
>
 
> - Chemical bonds required when amino acids are connected vertically: peptide bonds
 
>
 
> - Chemical bonds required when amino acids are connected horizontally: peptide bonds, cystine
 
>
 
> Bond, salt (ion) bond, hydrogen bond
 
>
 
> - Weak Bonds: Hydrogen Bonds, Salt Bonds
 
>
 
> - Strong binding: peptide bond, cystine bond
 
>
 
> - Permnant wave agents are responsible for breaking the cystine bond of transverse bonds
 
>
 
> - Principle of permant wave:
 
>
 
> * Reduction reaction of 1st solution: If 1 solution with high hydrogen (H) is treated on the hair
 
>
 
> Hydrogen enters between cystine bonds, i.e. -S-S-S- and reduces it to the -SH HS- equation
 
>
 
>The noodles are easily broken.
 
>
 
> (Thioglycolate and cysteine are used as reductants for the first solution)
 
>
 
> * Oxidation reaction of the second solution: To recombine the broken cystine bond
 
>
 
> When oxygen (O) is supplied, hydrogen combines with oxygen, so it becomes -S-S- again.
 
>
 
> (Sodium bromide (NaBrO3) high in oxygen is mainly used for oxidizing agent in the second solution

> ■ Director Yoon's column: Does oil flow even if I shampoo every day?
 
>
 
>
 
> It's like I didn't shampoo my oily hair and a bad smell just by looking too far
 
> Smell that smells!
 
> This is not an ordinary concern.
 
> However, many people are suffering from oily scalp.
 
> There are many reasons for oily scalp,
 
> Due to lack of vitamins or diet, our body lacks energy and hormones
 
> There will be a problem. At this time, cell division becomes difficult because nutrients are not properly supplied, and hair circulates by hair cycle.
 
>
 
> During the circulation process, the hair is dry and the sebaceous glands that create a protective film on the scalp
 
> It produces a lot of sebum.
 
> In the process, many sebums accept new fungi,
 
> This leads to a severe odor, dry hair, seborrheic hair loss, scalp purification, etc.
 
>
 
> To prevent this, you need shampoo and teaknick that fit your feet.
 
> Using oily shampoo, shampoo as if you're drinking it very gently,
 
> For the last rinse, rinse with water that feels a little cold.
 
>
 
> For oily shampoos, buy professional hairshops or sterilizing shampoos on the market,
 
> Products that are too focused on sterilization will dry your hair,
 
> You have to choose carefully.
 
>
 
> By the way!
 
> It's better to shampoo in the evening.
 
> The morning shampoo is alive, but put the outside pollution in your hair,
 
> If you sleep in that state, your scalp and hair can't breathe,
 
> When our body is resting, the scalp works hard to cause cell division,
 
> Because it's an important time to accumulate living energy the next day,
 
> Shampoo in the evening,
 
> After drying it, I sleep, and in the morning, I just put water on it and clean it up..
