Razor burn is the red, stinging, sometimes itchy rash that can appear straight after a shave. It is usually caused by technique rather than bad luck: shaving dry or in a hurry, using a blunt blade, or going against the grain. Soften the hair first, use a proper lather, shave with the grain using a sharp, rinsed blade, and finish with cool water and a calming balm.
In short
- Razor burn is surface irritation from friction. It usually settles on its own within a few hours to a few days.
- Shave after a warm shower, when hair is soft, and always use a cream or gel.
- Go with the grain. Fewer strokes, a sharp blade and no pressing.
- Rinse with cool water and use an alcohol-free balm afterwards.
- Bumps that keep coming back may be something else, so speak to a pharmacist or GP.
What is razor burn?
Razor burn is skin irritation caused by shaving. Cleveland Clinic describes razor burn as a red, blotchy rash that can burn, sting, itch or feel tender, and notes that it is common, usually lasts from a few hours to a few days and tends to clear up without treatment. The usual culprits are shaving dry, rushing, using a dull blade and shaving against the direction of growth.
It helps to separate two things people often lump together as “shaving rash”:
- Razor burn is a flat, blotchy irritation of the skin’s surface. It appears quickly and fades quickly.
- Razor bumps are small, raised spots that form when a cut hair curls back and grows into the skin. They take longer to appear and longer to go.
Should you shave before or after a shower?
After. The American Academy of Dermatology’s shaving advice is to wet your skin and hair to soften it before you shave, and says the best time is right after a shower. Warm water and steam swell the hair and make it easier to cut, which means less drag on the blade and less scraping across your skin.
No time for a shower? Hold a hot, damp flannel against your face for a minute or two. It is not quite as good, but it is far better than shaving cold.
How to shave properly: a close-shave routine
This is the routine we would give a friend. It is not complicated. Most of it is about doing fewer things, more slowly.
- Wash your face. Clean off oil, sweat and dead skin so the blade has a clear run. A gentle cleanser is enough.
- Soften the hair. Shave straight after a warm shower, or use a hot flannel. Hair that has been soaking for a few minutes cuts far more easily.
- Add a pre-shave oil if your skin runs sensitive or your stubble is coarse. A few drops massaged into damp stubble adds slip under the lather. Our Shave Oil is a pre-shave oil designed to soften whiskers and help the razor glide. We cover the details in our guide to pre-shave oil.
- Build a proper lather. Work a shaving cream or gel into the stubble with your fingers or a brush, against the grain, so it lifts the hairs. Leave it on for a minute.
- Shave with the grain. Short, light strokes in the direction the hair grows. Let the weight of the razor do the work. Do not press.
- Rinse the blade after every stroke. A clogged blade drags.
- Re-lather before a second pass, if you need one. Never go over bare skin with a razor. If you want it closer, re-apply cream and shave across the grain rather than straight against it.
- Rinse with cool water. Pat dry with a clean towel. Do not rub.
- Apply a balm. Something calming and alcohol-free, not a stinging splash.
How to get a close shave without irritation
A close shave and a comfortable shave are not opposites. The closeness comes from preparation and a sharp blade, not from pressure or extra passes.
Use a shaving cream that cushions
Cream or gel is not optional. It holds water against the hair and gives the blade something to glide on, so it cuts hair rather than skin. The AAD suggests that people with sensitive skin look for a shaving cream or gel made for sensitive skin. Our Shaving Cream gives a smooth, creamy lather and was designed with sensitive skin in mind.
Take fewer strokes
The NHS advice on ingrown hairs includes using as few strokes of the razor as possible and rinsing the razor after every stroke. Every pass removes a little of the skin’s surface along with the stubble.
Should you shave against the grain?
Generally, no, and certainly not on the first pass. The AAD recommends shaving in the direction the hair grows to help avoid razor bumps and irritation, and the NHS gives the same advice.
Going against the grain does cut closer, which is why people do it. The trade-off is more tugging, more friction and a higher chance of hairs being cut below the skin line. If you want a closer finish, re-lather and try a second pass across the grain (sideways) instead. Only go against it if your skin genuinely tolerates it, and never on the neck if you are prone to irritation.
Hair does not always grow in one direction. On the neck in particular it often swirls. Run your fingertips over a day’s stubble: the direction that feels smooth is with the grain.
Common shaving mistakes and what to do instead
| Mistake | Why it causes trouble | What to do instead |
|---|---|---|
| Shaving dry or with just water | No cushion, so the blade scrapes skin | Use a cream or gel every time |
| Shaving cold, first thing | Hair is stiff and harder to cut | Shave after a warm shower or use a hot flannel |
| Going against the grain on the first pass | More drag, hairs cut below the skin | Shave with the grain, re-lather for a second pass |
| Pressing hard | Removes more skin, causes nicks | Light strokes, let the razor do the work |
| Using a blunt blade | Tugs rather than cuts | Replace blades regularly |
| Not rinsing the blade | Clogged blade drags across the skin | Rinse after every stroke |
| Stretching the skin tight | Hair is cut below the surface and can grow back in | Keep the skin relaxed; the BAD advises against stretching it |
| Alcohol splash afterwards | Stings and dries freshly shaved skin | Cool water, then an alcohol-free balm |
| Leaving the razor in the shower | A wet razor is a poor place to store a blade | Dry it and store it somewhere dry |
Blades: sharp, rinsed and replaced
A blunt blade is one of the most common causes of razor burn. It does not slice cleanly through the hair, so it pulls and drags, and you compensate by pressing harder.
- Replace often. The AAD suggests changing your blade, or throwing away a disposable razor, after five to seven shaves. If it starts to tug before then, change it sooner.
- Rinse as you go. Hot water after every stroke keeps the edge clear.
- Store it dry. The AAD also advises keeping your razor in a dry place rather than in the shower or on a wet sink.
- Fewer blades can be kinder. Multi-blade cartridges cut close by lifting and cutting the hair in one stroke. If you get bumps, a single-blade razor or an electric shaver that leaves a little stubble can be gentler. The British Association of Dermatologists’ advice for people prone to razor bumps includes using a single-blade razor.
How often should you shave?
There is no rule. It depends on how fast your beard grows, how your skin reacts and what look you want. If your skin is calm and you like being clean-shaven every day, carry on.
If you get irritation, give your skin more time between shaves. The NHS suggests not shaving every day if possible to help reduce ingrown hairs, and the British Association of Dermatologists’ advice on pseudofolliculitis suggests shaving every other day and aiming to leave around a millimetre of stubble. A slightly less close shave, more comfortably achieved, is often the better look anyway.
Aftercare: what to do once the razor is down
The minutes after a shave are when your skin is most exposed. Keep it simple.
- Cool water first. It rinses off the last of the lather and feels calming on warm skin.
- Pat, don’t rub. Use a clean towel.
- Skip the alcohol. The old-fashioned splash stings for a reason. Freshly shaved skin does not need it.
- Use a balm. A light, alcohol-free balm leaves skin feeling soothed and hydrated. Our Post Shave Balm is alcohol-free and absorbs without leaving shine or an oily feel.
- Hands off. Do not pick at spots or try to dig out hairs.
When to see a pharmacist or GP
Ordinary razor burn is a nuisance, not a medical problem, and it usually settles once you change your technique. But some shaving rashes are something else.
Persistent bumps may be pseudofolliculitis barbae. The British Association of Dermatologists describes pseudofolliculitis, also called razor bumps or shaving bumps, as inflammation of the hair follicles and surrounding skin caused by hairs trapped beneath the skin surface. It is more likely with curly hair and is more common in men of sub-Saharan African descent, though anyone who shaves can get it. It is a skin condition, and no shaving product, ours included, is a treatment for it.
Speak to a pharmacist first. They can advise on shaving and on products for itching. See a GP if:
- spots or bumps keep coming back however carefully you shave
- an area is very painful, hot or swollen, or you feel unwell (the NHS lists these as reasons to contact a GP about ingrown hairs)
- spots are filled with pus, spreading, or leaving dark marks or scars
Whatever you do, do not scratch, pick or squeeze the bumps.
Frequently asked questions
How long does razor burn last?
Usually a few hours to a few days. Cleveland Clinic notes it typically clears up on its own. If redness or bumps are still there after several days, or keep returning, ask a pharmacist for advice.
Is it better to shave wet or dry?
Wet, for a blade. Shaving after a warm shower, with a cream or gel, softens the hair and gives the razor something to glide on. Dry shaving with a blade is one of the quickest routes to razor burn.
Does shaving against the grain give a closer shave?
It does cut closer, but it also raises the chance of irritation and hairs growing back into the skin. For most men, a first pass with the grain and a re-lathered second pass across the grain gives a close finish with far less trouble.
What should I put on my face after shaving?
Cool water, then a light, alcohol-free balm or moisturiser. Avoid stinging alcohol splashes on freshly shaved skin. If your skin is sensitive, patch test any new product on a small area first.
Can razor burn turn into razor bumps?
They are different things. Razor burn is surface irritation, while razor bumps form when cut hairs grow back into the skin. The same habits help with both: soften the hair, shave with the grain, use a sharp blade and do not shave too close.
