Pull out one white hair and ten will grow back? Beware of hair loss when pulling out hair forcefully

The main reason for growing white hair is the reduced function of cells to produce melanin. Therefore, the saying that the more you pull out white hair, the more hair will grow and ten will grow has no scientific basis. However, pulling out white hair can cause scalp inflammation. At the same time, several hairs will grow from the same hair follicle. If you forcibly pull out the white hair, it will affect the growth of other healthy hair and cause hair loss, etc. Therefore, pulling out white hair is not recommended. If you cannot tolerate the presence of gray hair, you can cut it off close to the scalp.

The more you dye your hair, the more gray hair you have?

Many people like to dye and perm their hair at the same time, which is fatal damage to the hair quality. In order to reduce the burden on the skin and hair, there should be at least 2 weeks between dyeing and perming.
