Ingrown hairs are hairs that were crimped by root and grew under the skin instead of growing out of it. They are not a serious problem, but are unsightly, and it’s frustrating when you want to have nice legs or look good in underwear.
Ingrown hairs produce skin irritation and inflammation that looks like a small pimple. Sometimes you can see the hair under the skin, sometimes you only see a small lump. If you’re not careful to treat it, you can get a serious infection. This problem is most common in people who have curly, thick hair.
