Ingrown hairs can be both uncomfortable and embarrassing. Ingrown hairs are caused by hair that has become curled and grows backwards into your skin.
This causes a red bump to form which may be itchy and can easily become infected and need to be removed.
No one knows exactly what causes ingrown hairs and they can spring upon any part of the body.
You might be more prone to it if you have thicker curlier hair and regularly shave or wax as this can make ingrowing hairs worse.
