Why everyone's hair is different

Everybody's hair has texture. That's what it looks and feels like. Your hair might be:

  • Straight, wavy, curly, or kinky.
  • Thick (a lot of it) or thin (not as much).
  • Fine (each hair is skinny) or coarse (each hair is fat). 

The shape of your follicles determines whether your hair is straight or curly. People with very curly hair have follicles that are oval-shaped and people with straight hair have round follicles. The kind of hair you have is decided by the genes you get from your parents.

Your hair may change its texture when you start becoming an adult. If it's straight now, it might become more curly. Or it might not.
