Vitamin B10 and Hair Care
Early use of vitamin B10 supplement was to aid in the repigmentation of hair that turns gray prematurely. Many people still use this method effectively, though there is not much research supporting it. Some studies have shown that taking vitamin B10 on a daily basis with doses between 200 mg and 2400 mg would restore the original color of gray hair or darken hair. However, more research is still needed to find out possible side effects and verify this link. [4]
