If a hair curls inward and starts growing in rather than out of the skin, it’s referred to as an ingrown hair.
An ingrown hair can look like a small bump or dot on your skin. Sometimes they’re painful or itchy. Sometimes they become inflamed or infected and may contain pus.
Ingrown hairs are commonly found in areas of the body that are shaved or waxes, including:
the face and neck
the front and back hair line
the armpits
the legs
the bikini area
