are there any vitamins or dietary supplements i can take to make my hair look healthier and grow stronger?
most people living in america receive enough of the vitamins and minerals needed for healthy hair through their diet and daily multivitamins. i do not routinely recommend any additional vitamins or supplements for healthier hair unless a specific deficiency has been identified in a person’s blood work. low ferritin -- a marker of the body’s iron stores -- can often be supplemented as can vitamins d and b12. however be cautious of over-ingesting certain supplements such as vitamin a arginine or selenium which can actually cause hair loss at very high doses.
