Let’s talk beta carotene here. You can easily prevent hair loss problem by regularly consuming sweet potatoes as these are packed with beta carotene. Your body converts this antioxidant vitamin to vitamin A. Vitamin A promotes the growth of healthy cells and tissues, including hair and the scalp. Vitamin A deficiency often results in dull, dry skin… which then flakes off of your scalp as dandruff. At the same time sweet potatoes also contain plenty of vitamin C, copper, iron and protein. You can eat boiled or baked sweet potatoes depending upon how you like it.
