There are many reasons for white hair. At present, melanocytes are mainly related to heredity, age, nutrition and so on. The effective components in Polygonum multiflorum Thunb are polyphenols and flavonoids, which may be helpful to hair. But in real life, it is not clear that Polygonum multiflorum Thunb can turn white hair into black hair.

The best way to improve the color and quality of hair is to maintain good nutrition and living habits, such as a balanced diet, proper exercise, and not excessive dyeing. Once you find something wrong with your hair, you need to consult your doctor and hairdresser. Of course, in terms of toiletries, we also need a reasonable choice.

The method of maintaining hair is:

1, eat more foods rich in vitamins B and C.

Usually eating more fresh vegetables and fruits rich in vitamin B and vitamin C, such as malt, has a multiplier effect on restoring healthy and shiny hair.

2. Precautions for perm and hair dyeing

Perm your hair at most twice a year. When the hair quality becomes worse, it is recommended not to perm and dye it, and it is best not to dye and perm it at the same time, because these two potions will cause double harm to your hair.

3. Supplement protein

When the hair lacks protein, it will also be fluffy and short-tempered. The loss of protein will make the hair lack nutrition, so eat more meat, eggs and soybeans to supplement protein, so that the hair will no longer be dry, short-tempered and dull.

4. Avoid exposure to the sun

Hair should also pay attention to sun protection. In fact, the ultraviolet damage to hair is more than twice as serious as that to the face. Ultraviolet rays can make hair scales thin and peel off, and strong sun exposure can make hair lose moisture and become dry and rough. Long-term ultraviolet radiation will split and break the hair.
