You're probably most familiar with the benefits antioxidants can provide in skin care, but according to sources at Livestrong, they also play a key role in producing hair growth. The antioxidants found in pumpkins are impressive: Vitamin E is known to enhance blood circulation in the scalp (which may promote hair growth) and vitamin C strengthens hair follicles. You definitely shouldn't be turned off by the hard, orange exterior of pumpkins because that bright orange color is a sign of beta-carotene which converts to vitamin A in our bod's which is a vitamin you don't want your scalp missing out on. The best part about pumpkins is that every part can be used whether it's snacking, hair and skin treatments, or fall crafts.
