So I have read several natural black hair books and e-books and many have suggested ways to stimulate your scalp to promote healthy hair growth. In one book they even went so far as to suggest doing some headstands or hanging your head off the bed for 5 minutes each day. At first I was kind of like, 'pshhh yeah right' but then I saw other books recommending similar if not better ways to stimulate your scalp to encourage growth. Many of us might resort to using creams, pills, shampoos that make your scalp tingle, etc to promote hair growth.
