A big ingrown hair, also known as an "embedded hair" or "incarnate hair," is a hair that grows back into the skin instead of emerging from it. This occurs when the sharp tip of a broken hair curves back and penetrates the surrounding skin. A common example of a big ingrown hair is one that develops after shaving or waxing, particularly in areas where the hair is coarse and curly, such as the legs, underarms, and pubic area.
Big ingrown hairs are not only unsightly but also uncomfortable and sometimes painful. They can become infected and lead to further complications. Historically, methods of preventing and treating big ingrown hairs have evolved over time, from the use of topical ointments and exfoliating scrubs to laser hair removal.
