With gray hair, shampoo is usually not immediately hair black, the number is at most to show a lot of nutrients to the hair, improve the hair black condition. Pick the right shampoo together with the need to pay attention to vitamin supplementation, eat more vitamin B6, vitamin E, vitamins have the effect of preventing hair gray and promote hair growth. For example, oatmeal, peanuts, beans, bananas and apples, yeast, pure honey, eggs and beef liver. There is no need to perm your hair too often and apply hair dryer too often, as this allows the sebaceous glands at the top of the head to spread more evenly throughout the hair, which is good for the maintenance of the hair and maintains its luster. Gray hair not only jeopardizes the design of appearance, and will also be old and jeopardize the mood of the person. In my opinion, if you have gray hair, don't be anxious, add mulberry leaves, cypress leaves or ginger slices when you wash your hair, it will help your gray hair to become black. Mulberry leaves is the king of green plants, ginseng hot tonic, mulberry leaves clear tonic reputation, mulberry leaves contain 17 kinds of carbohydrates in the body, with mulberry leaves decoction hand wash, can promote hair growth, so that hair more and more black and bright, but also can make the hair loss of serious people have been no hair loss. Side of the cypress leaves have the effect of black hair, for less white head patients, can be side of the cypress leaves boiling water decoction soup wash hair. Ginger also has a role in the treatment of hair loss, to prevent the effect of gray hair, which I think because of the ginger in the ginger, can promote the body of the top of the head of the blood circulation system, and then stimulate the hair hair follicles to open, so that the growth of new hair to go out, but this kind of way is not suitable for anyone.
