When an ingrown hair develops, you may notice small, round bumps called papules, or small, pus-filled bumps called pustules. In some cases, the skin around the ingrown hair may become darker. This is known as hyperpigmentation. You may also experience pain or itching around the area of the ingrown hair.
Certain people may be at a higher risk for ingrown hairs. For example, people with thick, curly hairtend to develop ingrown hairs more often than people with fine, thin hair. This is especially true with pubic hair, which tends to be coarser than hair on the head or the rest of the body.
