Fan Palm’s large boar and nylon bristle brush has been designed to add shine and smooth hair as it gently massage and stimulate your scalp. The nylon bristles are longer and gently stimulate the scalp and help detangle the hair while allowing the boar bristles to distribute sebum. It stimulates blood flow to the hair follicles which can improve hair growth. Most find that they can reduce the frequency of hair washing to every three or four days. It is great for all hair types.
