Nutrafol for Women, $88, is specifically aimed at fighting hair loss. It helps balance stress hormones (you can end up with excessive shedding when they're out of wack), and it has ingredients like hyaluronic acid and marine collagen to nurture each hair follicle. Add to that the fact that it has 15 patented ingredients and seriously impressive clinical results, and you've got one home run of a hair vitamin.

Keranique recently did a survey that found the number of women struggling with hair loss is up 50 percent in the last 10 years. The Keranique Daily Essentials, $49, has biotin, beta-carotine and a procollagen blend to encourage hair to grow thicker and fuller.

Phyto is known for their scalp-nourishing approach to hair care so it makes sense that they'd have a hair vitamin. In addition to GLA (notice a trend?), it contains Vitamin E for its antioxidant properties, and B and C for hair growth and shine.
