The treatment of white hair is very difficult. There is basically no good way to treat juvenile white hair caused by genetic reasons. Some non-hereditary premature gray hair, pay attention to diet conditioning, relax, and use Chinese herbal medicines appropriately, still have certain effects. In a person's life, the color of hair is determined by the type and quantity of melanin particles in hair. With the increase of age, the formation of melanosomes in hair decreases and local hair begins to turn white. White hair often starts from the sideburns, then reaches the hairline and finally reaches the top of the head. Hair turns white early, some turn white as soon as it is pinched, some turn white on the top of the head, and some just mix in a few white hairs. What about white hair? A small amount of white hair mixed with black hair can be cut off or torn off at the root. You can also dye your hair once in a while. Hair dye contains lead, which can cause skin allergy and contact dermatitis. If you don't have these symptoms, you can dye your hair when the new white hair grows obviously, but not too many times. If it is a small part of white hair, you can transplant hair follicles and implant black hair. This can be done in medicine, but few hospitals and Zhu Juan do it. Premature hair growth may be related to some nutritional deficiencies. Some nutrients, such as cystine, can be supplemented appropriately. Cystine is an amino acid, which is a nutrient for hair keratin and can also supplement trace elements such as copper and zinc. The lack of copper and zinc in hair will lead to the reduction of synthetic melanin. After the hair turns white, it can be conditioned with traditional Chinese medicine, which can be used to condition and turn white hair into black hair. When cooking soup at home, you can put some Chinese herbal medicines, such as Fructus Corni, Polygoni Multiflori Radix, Radix Rehmanniae Preparata, Walnut, Ganoderma lucidum, Fructus Lycii, Fructus Ligustri Lucidi, Ruby, Radix Asparagi, Rhizoma Polygonati and Radix Angelicae Sinensis, or soak Semen Sesami Niger or Polygoni Multiflori Radix in water. Polygonum multiflorum Thunb. is 20-30g per day. If it is hot and dry, angelica is generally not used. Soaking chrysanthemum tea and eating walnuts at ordinary times can clear the liver and improve eyesight, which is good for turning white hair black. Relaxation is very important. If you are too nervous and anxious for a certain period of time, it will lead to an increase in the release of catecholamine in the brain and a decrease in tyrosinase activity, thus affecting the metabolism of melanin and reducing the synthesis of melanin in hair.
