Carolyn Jacob, MD, founder and medical director of Chicago Cosmetic Surgery and Dermatology, tells WebMD, “Any vitamin deficiency will cause hair loss. All the vitamins are important — B, C, E.” But that doesn’t mean, as she and other experts point out, that you need to buy special supplements for your hair.
“The best source for the nutrients you need,” Jacob says, “is a true, well-balanced diet.” If you are going to take an over-the-counter supplement, Jacob says, talk with your doctor or nutritionist to make sure you’re “getting a high-grade women’s multivitamin that will ensure you get what you need.”
