The most important hormones affecting the health of skin, hair and nails are estrogen (especially in proportion to testosterone), thyroid hormones and cortisol. Estrogen: Not surprisingly, estrogen levels affect every part of the body, including hair, skin and nails.
Biotin (a.k.a. vitamin H) can improve hair that is splitting or thinning as well as strengthen weakened nails. Taken with zinc and the corticosteroid clobetasol propionate, biotin has even been used to treat alopecia, an autoimmune skin disease marked by the loss of hair.
