The best way to prevent ingrown hairs from occurring is to avoid tweezing and plucking the hair and allowing it to grow freely. It can also be helpful to apply a topical hair growth inhibitor after tweezing to help prevent the occurrence of ingrown eyebrows.
An ingrown hair occurs when the end of an eyebrow hair is sharp enough to grow back down into the skin, once it begins growing out again. An ingrown hair usually occurs in an area where the hair is very coarse, such as the beard for a man and the bikini area on a woman, but it can also occur on other areas of the body, including the eyelids.
Generally, an ingrown hair will first make its appearance as a small red bump or a dark area underneath the skin; it can start as an itchy and irritated place on the skin, which can lead to painful pus-filled bumps and redness.
Ingrown hairs can be treated by moistening the area with a warm, wet washcloth and then scrubbing the area in a gentle circular motion with the same cloth. A sterile needle may also be used to dislodge an ingrown hair to help relieve pain.
