What are some good hair vitamins for black hair?

Biotin, inositol, copper, zinc and methylsulfonylmethane, or MSM, are vitamins that are good for promoting hair growth in African-American women, according to Black Doctor. Eating a healthy diet is also beneficial.

Biotin is a water-soluble vitamin that promotes fast hair and nail growth and healthy skin, Black Doctor notes. Inositol strengthens the hair by maintaining moisture in the hair follicles. MSM is a natural form of sulfur that promotes the formation of keratin, a protein that strengthens hair and nails. Copper is a mineral that increases production of collagen and elastin. Zinc is necessary for the health and growth of hair, and American women are often deficient.
