dietary supplementation
"Biotin is pure bliss. I have been taking it everyday at 5000 mg. It has definitely made improvement in my nails and hair. I have been taking it for a few months and my hair has grown almost two inches. Reading tons of negative reviews on other sites at first made me think that biotin would barely do anything, but that was wrong biotin definitely helped my hair, skin, and nails! Taking this everyday and sticking with it really makes a difference!"
