An ingrown hair is caused by a small hair under the skin that does not grow outward through the skin as it should. Instead, the tip of an ingrown hair grows sideways or curls back into the hair follicle to cause a localized area of skin irritation and inflammation. Ingrown hairs commonly occur on the face, neck, armpits, pubic region, and legs. 2  This condition is usually caused by shaving, waxing, or tweezing hair. 3  Ingrown hairs can cause pain and itching, and they can become infected.
