What causes ingrown hair?

ANSWER

Anyone can get an ingrown hair. But the problem is more common in people who have very curly or coarse hair. Curly hair is more likely to bend back and re-enter the skin, especially after it's been shaved or cut. Also, people with high levels of certain sex hormones can have excessive hair growth, which makes it more likely to get ingrown hairs, especially after shaving. Many African-Americans, Latinos, and people with thick or curly hair develop a type of ingrown hair called pseudofolliculitis. More commonly known as "razor bumps," this collection of little bumps is common on the beard area after you've shaved, waxed, or tweezed to remove unwanted hair. The hair that grows back has a sharper edge, so it can more easily poke back through the skin and get trapped under the surface.
