what causes curly hair
Anyone with curly hair knows that this hair type can be dry, hard to manage, and often frizzy. The good news is that people with curly hair tend to have fewer split ends than people with straight hair.The amount of curl in curly hair is also dependent on the shape of the hair follicle and shaft. The hair follicle below the scalp has a hooked end in people with curly hair.t is known that curly hair has a different biological structure than straight hair. It is extremely rare to find someone with hair that is both curly and oily. Biologically, this makes sense, because the oils secreted into the hair shaft by the sebaceous glands can more easily travel down the shaft of straight hair.
