Ingrown hair is a condition that affects the skin when hair, instead of growing outward, curls back and grows into the skin. It can cause pain, inflammation, and scarring.
Healing ingrown hairs is important because it can help prevent infection, reduce pain and inflammation, and improve the appearance of the skin. One of the key historical developments in the treatment of ingrown hairs was the invention of the laser in the 1960s. Lasers can be used to remove ingrown hairs quickly and effectively with minimal scarring.
