Folliculitis (razor burn)

 

What is folliculitis (razor burn)?

Folliculitis is red bumps or pimples that form around hair follicles—often on the scalp, neck, chest, back, or thighs. When it appears after shaving, it’s called razor burn. It looks similar to acne and usually improves with the same treatments.


What causes folliculitis?

It’s not fully understood why some people get folliculitis and others don’t. Often, bacteria enter a hair follicle through shaving, tight clothing, or hats/helmets, leading to a red bump or pimple.

Stress also plays a role—physical, mental, or emotional stress can trigger flare-ups in your usual spots. For example, I often notice 3–4 new bumps on the back of my head before a big presentation or deadline.


How do I treat folliculitis?

Most people improve with a few simple steps, though it may take some trial and error:


Steps for using a medicated acne wash or Hibiclens:

In the shower, rinse your problem areas, then:

  1. Apply benzoyl peroxide wash or Hibiclens wash and leave it on for 5–10 minutes so the medication can soak in before rinsing.

  2. Use benzoyl peroxide wash or Hibiclens wash once or twice daily. You do not need another face/body wash. Avoid exfoliating scrubs.

Notes:


What if my folliculitis is caused by shaving?

If bumps appear in areas you shave (face, neck, scalp, thighs, groin):

⚠️ Don’t leave your razor in Hibiclens all day—it will rust. Never shave with rusty blades.


What if my folliculitis isn’t getting better?

Most people improve with the steps above, but sometimes prescription creams or antibiotics are needed. In severe or scarring cases, isotretinoin (Accutane) may help. If over-the-counter treatments aren’t enough, look for a board-certified dermatologist in your area. If you are in or near Utah, see one of my excellent colleagues at the University of Utah or me virtually with Honeydew.
