A blocked hair follicle, medically referred to as folliculitis, is a common condition characterized by the inflammation and infection of one or more hair follicles. This blockage can arise due to various factors, including dead skin, dirt, or bacteria accumulation. An everyday example is the occurrence of "razor bumps" after shaving, which are essentially inflamed hair follicles.
Understanding blocked hair follicles is of great relevance in dermatology, as it can lead to skin irritation, scarring, and hair loss. Effective management and treatment of this condition not only improve skin health but also prevent potential complications. Historically, the development of antibiotics has significantly advanced the treatment of infected hair follicles.
