Kiwi fruits are a fantastic source of vitamin C. Although there is no confirmed direct role for vitamin C in hair growth, one of its major functions in the body is as an antioxidant. This antioxidant activity may help to protect the hair follicles and encourage growth.
Of course, vitamin C is also essential for the immune system, and as we’ve already seen, when the immune system is properly balanced it is less likely to react against the hair follicles. Like many other colourful fruits, kiwi fruits also contain a wide variety of flavonoids and carotenoids, which can also act as antioxidants. Kiwi fruits also contain small amounts of copper, a mineral that is known to contribute to hair pigmentation.
