Biotin, also known as vitamin H or B7, is one of the important vitamins for supporting hair growth. Biotin helps to produce the substances necessary for the growth of hair and nails: nail cement and keratin.

Biotin is used in cell growth and metabolism of fats and amino acids. Biotin also plays a key role in metabolizing the energy you get from food. Biotin binds easily to proteins, making it unavailable to your body, which in turn causes biotin deficiency and hair loss.

Fatty acids are a valuable growth factor in numerous processes in the body including the hair.

Hair loss is one of the initial symptoms of biotin deficiency. Other symptoms may include fine and brittle hair, dry skin and fungal infections.

Many dermatologists prescribe biotin supplements to their patients as part of their medical treatment for hair loss.

Many patients who are taking Propecia and Proscar are taking a biotin supplement.

Balding men might find that a Biotin supplement may keep their hair longer.

Biotin is available within multivitamins and B-vitamin complexes, and as individual supplements.

Food sources of biotin include egg yolks, brewer’s yeast, liver, brown rice, bulgur, green peas, lentils, oats, soybeans, sunflower seeds, walnuts and milk.

Daily dose: 150-300 mcg.
