Your hair needs many essential vitamins and minerals in order to grow. Luckily, a lot of those are already in your diet. If you’re looking for a vitamin supplement to support healthy hair growth, find a product that contains any of the following: vitamin A, vitamin B7, vitamin C, vitamin D, vitamin E, omega-3s and zinc. 

Multivitamins are always an option, as there are many hair multivitamin products on the market. Multivitamins are best if you’re looking to cover every base when it comes to your essential vitamins and minerals. 

Prenatal vitamins or prenatal multivitamins often include vitamins B12, C, D, E, iron, zinc, folic acid, calcium, thiamin and iodine. Of these, vitamin C, vitamin D, vitamin E, iron, folic acid and zinc are good for hair growth. While it’s not recommended to take prenatal vitamins solely for hair purposes, prenatal vitamins do include nutrients that aid in hair growth. If considering a vitamin supplement for hair growth, look for a supplement that contains similar vitamins and minerals. Always talk with your doctor before considering prenatal vitamins.  

Nutrafol offers a product for postpartum women in the first year after birth or breastfeeding. 

Men’s hair requires similar vitamins as women’s hair, but the cause of hair loss and hair thinning is different in men than women. Male pattern baldness is linked to both genetic and hormone factors. Recent research has shown that vitamin D deficiencies are associated with male pattern baldness. Hair supplements for male pattern baldness often include ingredients such as soluble keratin, kelp, horsetail, root extract and antioxidants, but the research on the effect of these ingredients on hair is still being conducted.
