Folliculitis causes small, itchy red or pus-filled bumps around hair follicles, most often from bacteria, shaving or friction, ingrown hairs, or hot tub exposure. Mild cases often clear with gentle washing, warm compresses, and pausing shaving, but persistent, widespread, very painful, or feverish cases and those in people with diabetes or weakened immunity may need prescription antibiotics or antifungals and sometimes drainage; see below for detailed causes, prevention, look-alikes, and step-by-step guidance that can shape your next care decisions.
If you've noticed clusters of red, irritated bumps around hair follicles, you may be dealing with folliculitis. These bumps can look like acne, feel itchy or tender, and sometimes even fill with pus. While folliculitis is usually mild, it can occasionally become painful or spread if not treated properly.
The good news? Most cases clear with the right care. Understanding what causes folliculitis, how to treat it, and when to seek medical help can make a big difference in how quickly your skin recovers.
Folliculitis is inflammation or infection of one or more hair follicles. Hair follicles are tiny openings in your skin where hair grows. When they become irritated or infected—most often by bacteria—you can develop small red bumps that may resemble pimples.
Folliculitis can occur anywhere you have hair, including:
In mild cases, folliculitis may cause only minor discomfort. In more serious cases, it can deepen into painful boils.
The most common cause of folliculitis is bacterial infection, especially from Staphylococcus aureus. However, bacteria are not the only trigger.
Hot tub–related folliculitis, for example, is often caused by Pseudomonas bacteria and may appear within days of exposure.
Folliculitis often appears as:
In some cases, deeper infections can form:
If left untreated, deeper infections can cause scarring.
Most cases of folliculitis are mild and resolve within 1–2 weeks with basic care. However, complications can occur if:

Treatment depends on how mild or severe your folliculitis is.
Many cases improve with simple measures:

It is important to complete any prescribed antibiotic course, even if symptoms improve early.
When folliculitis becomes deep, painful, or recurring:
Never attempt to squeeze or drain boils at home. This can worsen infection and spread bacteria.
Preventing folliculitis often involves reducing irritation and bacteria exposure.
If you frequently experience folliculitis in the beard or bikini area, changing grooming habits can significantly reduce flare-ups.
Individuals with diabetes are more prone to skin infections. Even mild folliculitis should be monitored carefully to prevent complications.
People undergoing chemotherapy, taking steroids, or living with immune disorders may experience more severe infections and should seek medical advice early.
You should seek medical attention if:
While folliculitis is usually manageable, untreated deep infections can lead to cellulitis (a more serious skin infection), scarring, or abscess formation.
If anything feels severe, worsening, or life-threatening, speak to a doctor immediately.
Because folliculitis can resemble acne, confusion is common.

Treatment differs, so proper identification matters.
Folliculitis is common, uncomfortable, and sometimes frustrating—but usually treatable. Most cases resolve with good hygiene and simple care. However, deeper infections like furuncles and carbuncles require medical attention.
