Sweet potatoes

Sweet potatoes are not only one of the brightest vegetables but also a great way to encourage the production of keratin. They contain especially high levels of provitamin A carotenoids. Provitamin A carotenoids like beta carotene are converted into vitamin A in the body, which is linked to hair health.

The amount of provitamin A in a medium sweet potato, or 150 grams, is 1,150 mcg, or more than 100% of the DV. Keratin synthesis is supported by vitamin A, which is crucial for healthy skin and hair. This orange root vegetable provides substantial amounts of potassium, manganese, and vitamins B6 and C in each serving. Research has shown that vitamin A can affect the production of sebum, which helps keep hair healthy. Vitamin A deficiency can lead to hair loss.
