Hair grows from tiny holes in your skin called follicles. It’s made of a strong protein, like what your nails are made of. The part of hair you see is dead, so it doesn’t hurt when you cut it. Hair gets its color from something called melanin, which makes hair black, brown, blonde, red, or other colors. Hair helps protect your body—like eyelashes keep dust out of your eyes and hair on your head keeps you warm. Hair grows, falls out, and then new hair grows back in its place. Different people have different kinds of hair—some have curly hair, some have straight hair.
