6Sweet Potatoes
Sweet potatoes are high in beta-carotene, which would be converted into vitamin A to boost your hair health. Studies have proved that vitamin A would boost the production of sebum, which would keep hair healthy. In addition, it can speed up the growth of new hair, thus allowing for thicker hair on your head. It can also prevent other hair follicles from being damaged or regressing. A typical sweet potato can provide more than 4 times your daily needs of vitamin A. [6]
