What Is Folliculitis?
Folliculitis refers to an infected hair follicle. This typically appears as small red, yellow or white bumps on the skin. While commonly referred to as “razor burn,” folliculitis is usually caused by damage to the hair follicle but can also be caused by a bacterial, viral, or fungal infection. The condition is very common, affecting millions in the US every year.

Your primary care physician can diagnose folliculitis, but they will likely refer you to a dermatologist for treatment and further diagnostic testing. Your physician will likely order blood tests to rule out certain underlying conditions that can lead to folliculitis.
Treating folliculitis depends on the underlying cause. In cases that are caused by skin irritation (shaving, waxing, etc.), topical antiseptics can resolve the infection and inflammation. Using proper shaving cream for shaving can reduce the likelihood of razor burn reoccurring. Medications like oral antibiotics or topical antifungals may be needed for cases of folliculitis that are caused by infections.
