I've been using expensive shampoo because I've suffered from seborrheic skin, but I've almost used it up, so I'm testing it with a c*** sold on the market. Is it a surfactant problem? On the 11th day, the itchiness is extremely high, and it's falling out because it's swollen and dandruffy. It's surprising to see such a change with just one shampoo. The concern is that there is no way to know if the existing expensive shampoo is really eco-friendly and calming the scalp or if it is strong and forcibly calms the scalp. After all, washing with expensive shampoo today removes a lot of itchiness. What's wrong with seborrheic scalp? Is there a way for people like me to do this? Shampoo sold in various markets doesn't fit me.. Like the person who left a comment last time, I should use natural soap. Polly shampoo doesn't fit me either... I'm worried.
