An ingrown hair scar is a type of skin lesion that occurs when a hair grows back into the skin instead of out. This can happen anywhere on the body, but it is most common in areas where hair is shaved or plucked, such as the face, legs, and armpits.
Ingrown hair scars can be unsightly and uncomfortable. They can also lead to infection if they are not treated properly. However, there are a number of treatments available to help reduce the appearance of ingrown hair scars and prevent them from becoming infected.
