What Causes Ingrown Hairs
The most common cause is after-shaving, scraping, or waxing. Growing hair tends to have sharper ends, then curl and bend to re-enter the skin layer. Hair that enters the interior of the skin is considered a foreign object by the layers of your skin and body, so the body responds with symptoms of itching, redness, and swelling. This condition is also triggered by a buildup of dead skin that covers the hair follicles so that hair cannot grow normally.
