The bristles of a brush can damage the scalp and tear the hair cuticles, especially if used on kinky curly hair, which is extremely fine and fragile. Although, if done correctly, brushing can help stimulate hair growth by strengthening the follicles and spreading natural oils, such as sebum, throughout the hair; it is much safer to gently use a comb or your fingers to stimulate the scalp. Since you won't be spreading oils with a brush, you can simply apply an oil treatment directly to the ends. If you feel that you must brush, only use one with natural boar bristles and never brush wet hair.
