Eczema and dermatitis are both symptoms of a biotin deficiency and both of them can result in the loss of hair due to the build up of excess layers of skin in the scalp and the itching that accompanies the condition. The more a person scratches her scalp, the more likely that person is to suffer hair loss. Eating foods plentiful in biotin or taking vitamin H (biotin) supplements can provide relief from the skin conditions and result in less loss of hair and the regrowth of new hair. 5mg of biotin, taken daily, is what is needed to re-grow hair and strengthen existing hair follicles to prevent hair fall-out.
Biotin Rich Foods
Biotin can be found in peanuts, peanut butter, egg yolks, organ meat, such as liver, and soy products. If you have a strong craving for peanuts it is possible that you are deficient in biotin. It can also be found in mushrooms, tree nuts, dairy products, bananas and yeast. The Western diet, which is very strong in these particular foods, provides a considerable amount of biotin, but even then supplements can still be taken as there are no proven side effects of vitamin H excess. The body simply uses what it needs and sheds the rest through the waste removal organs.
Shampoos and Conditioners
Biotin applied directly to the scalp through the use of shampoos and conditioners containing the vitamin, can penetrate not only the scalp, improving the health of the hair follicles; but can also penetrate the follicles themselves, strengthening the existing hair, which helps it to grow longer. If you have chemically damaged hair, from overuse of permanents or colorings, you can give your damaged hair a lift by using shampoos, conditioners and other hair treatments that contain biotin. Biotin is strongly connected to healthy hair growth as it is part of the chemical make-up of hair. No matter how healthy your hair is, it can only be assisted by the addition of a biotin-rich diet.
