Not to long ago i got an email talking about this subject and wanted to share this with all of you beauty lovers :)
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. Nina DiBona, RD, dietitian and nutritionist at the Sports Club/LA in Boston , agrees. “A deficiency in biotin may result in brittle hair or even hair loss.” An easy way to remember: The H in vitamin H stands for “haar and haut,” which means “hair and nails” in German, DiBona notes.
