Ingrown Hairs, Razor Bumps and Folliculitis: Causes and Treatment
Ingrown hairs are hairs that curl back and grow into the skin, causing raised, itchy bumps. Razor bumps (pseudofolliculitis barbae) are inflamed ingrown hairs triggered by shaving. Folliculitis is inflammation or infection of the hair follicles themselves. All three are common, closely related and very treatable.
Almost every man who shaves has met at least one of them. They cluster where hair is coarse and skin is under pressure: the beard and neck, the back of the scalp, the groin, the chest and the thighs. They are usually harmless, but they can sting, itch, scar and knock your confidence, and a stubborn crop of bumps can make shaving feel like a losing battle.
The good news is that the fixes are mostly simple, and the more severe forms respond well to treatment a GP can arrange. This guide walks through what causes each one, how to treat them, and the shaving technique that stops them returning.

Shaving cuts hair at an angle, leaving a sharp tip. On curly or coarse hair, that tip can curve back and pierce the skin as it grows, or grow sideways within the follicle without ever surfacing. The body treats the buried hair as a foreign object and responds with inflammation: a firm, itchy or tender bump, sometimes with a visible loop of hair inside it.
Razor bumps, medically pseudofolliculitis barbae, are this process happening across a whole shaved area, most often the beard, neck and jawline. Men with curly hair are far more prone, and very close shaves make things worse because the hair retracts below the skin surface before it is cut. Multi-blade razors, dry shaving, shaving against the grain and stretching the skin while shaving all raise the risk. The result is a rash of bumps that reappears a day or two after every shave, right on schedule.
Folliculitis is different: here the follicle itself becomes inflamed or infected, whether you shave or not. It looks like small red bumps or white-headed pimples scattered around hair follicles, and it can affect the beard, scalp, chest, back, buttocks and thighs.
Bacteria are the most common trigger, often after shaving, waxing, friction from tight clothing, or long sweaty sessions in synthetic gear. Spa and hot tub use can cause its own version. Yeasts can also be responsible, particularly on the chest and back of men who train hard and stay in damp clothes afterwards.
Folliculitis on the face is regularly mistaken for acne, but acne comes with blackheads and responds to different treatment, and adult acne has its own set of drivers. If bumps sit strictly around follicles and flare after shaving or sweating, folliculitis is the better bet, and the treatment is different.
Mild cases usually settle on their own within a week or two once you remove the trigger. Give the area a break from shaving, apply a warm compress a few times a day to soothe bumps and help trapped hairs release, and wash with a gentle antiseptic wash. Resist squeezing: digging at buried hairs pushes inflammation deeper and is the surest route to scarring.
Persistent or more severe cases respond well to prescription treatment. Depending on the cause, a doctor may suggest topical antibiotics, a course of oral antibiotics, topical antifungals for yeast-driven folliculitis, or a short run of a mild corticosteroid cream to settle inflammation. Our Help Centre explains what can be prescribed online safely, and online prescriptions go straight to your pharmacy. If your skin is dry or eczema-prone, gentler products matter even more; our adult eczema guide covers the skin-barrier care that helps here too.
Technique changes prevent more razor bumps than any product. The goal is to cut hair cleanly at skin level, not below it, with as little scrape as possible.
- Shave after a warm shower, when hair is soft, and always with a generous lather.
- Shave with the grain, in single strokes, without stretching the skin.
- Swap a multi-blade razor for a single blade, or an electric shaver on a guard setting.
- Rinse the blade after every stroke and replace it regularly; dull blades tug and tear.
- Finish with a fragrance-free moisturiser rather than an alcohol-based aftershave.
If bumps persist regardless, consider keeping stubble at a millimetre or two with clippers instead of shaving to the skin. For many men with coarse or curly hair, this single change makes the biggest difference of all. It is not about giving up on being clean-shaven forever, but about letting the skin recover fully before reintroducing a gentler routine.
Care that remembers your skin
Most bumps never need a doctor. Book an appointment if bumps are spreading or becoming more painful, if any lump grows large, hot and filled with pus, if folliculitis keeps returning despite good technique, or if you are developing dark marks or raised scars, which are easier to manage early.
Recurrent skin infections are also occasionally a flag for something underlying, such as type 2 diabetes, which makes skin infections more likely and slower to heal. And bumps in the groin deserve an honest look: if they do not behave like ingrown hairs, an STI check is a sensible, routine step rather than a drama.
One situation is urgent: if redness is spreading quickly from a boil or infected area and you feel very unwell with fever, chills or confusion, call 000 or go straight to your nearest emergency department.
Abby Health is an online-first clinic, and skin problems suit telehealth well: a doctor can assess the affected area by video and take a proper history of your shaving routine, training habits and skin care. Appointments are available seven days a week, 365 days a year, usually the same day.
Your doctor can confirm whether you are dealing with razor bumps, folliculitis or something else, arrange prescription treatment where home care has not been enough, and refer you onward in the uncommon cases that need it. Because you can choose your clinician and book the same doctor each time, progress gets reviewed by someone who has actually seen your skin before, not a stranger starting from scratch. Bulk billed for eligible patients with a valid Medicare card. Strict eligibility criteria apply.
