Laser hair removal is one of the most effective long-term options for razor bumps and ingrown hairs on the neck and jaw. Fewer, finer hairs means fewer hairs curling back into the skin, so the bumps stop forming instead of being treated after they appear. Inflamed skin is settled first, and darker skin needs carefully chosen settings.
TL;DR
- Razor bumps (pseudofolliculitis barbae) are caused by shaved hairs growing back into the skin. They are not mainly an infection.
- Coarse, curly hair and close shaving make them more likely.
- Better shaving habits help, but stopping shaving is the only certain cure. Laser reduces the hair that causes the problem.
- Actively inflamed skin, dark marks and recurring painful lumps in the armpits or groin are dealt with before laser, or by a GP.
- The neck usually needs 8 to 10 sessions, every 4 to 6 weeks.

What razor bumps are
Razor bumps are small, red, often tender bumps that appear after shaving, most often on the neck and under the jaw. The medical name on the face and neck is pseudofolliculitis barbae. The British Association of Dermatologists describes it as inflammation caused by hairs trapped under the skin’s surface, rather than an infection. It is most common in men who shave, and in anyone with coarse or curly hair.
Why shaving closer makes it worse
Many men try to fix razor bumps with a closer shave. It usually makes things worse. A hair cut very short retracts below the surface, and its sharp tip is more likely to curl back into the skin as it grows. Neck hair that grows in swirls adds to the problem, because there is no single shaving direction that works everywhere.
What helps before laser
Changing how you shave can reduce the bumps:
- Shave with the grain, using a single blade
- Shave every other day rather than daily, or leave a little stubble
- Avoid plucking ingrown hairs out
- Exfoliate gently a few times a week
These steps help many men, but they need doing every time you shave. If you have tried them and your neck still breaks out, reducing the hair itself is the next step.
How laser hair removal helps
Laser hair removal reduces the number and thickness of the hairs that grow back. With fewer, finer hairs, far fewer are left to curl back into the skin, and most men notice their neck becoming calmer as the course goes on. Many find they can shave less often, or not at all, on the treated area. Results vary, and hair reduction is long term rather than a guaranteed removal of every hair.
What we settle first
Not every bump on the neck is a razor bump, and some skin needs to calm down before laser:
- Actively inflamed or infected skin. Treating angry skin can swap a shaving rash for a pigment problem.
- Dark marks from old bumps. These are post-inflammatory pigmentation, not scars, and are treated once the hair is under control.
- Recurring painful lumps in the armpits or groin that leave tunnels or scars. This pattern can be hidradenitis suppurativa, which needs a GP rather than a laser course.
- Acne on the neck and jaw. It needs treating as acne, not as ingrown hairs.
- Skin over-treated at home with strong acids or scrubs, which usually has to settle first.
Razor bumps on darker skin
Razor bumps are more common in men with tightly curled hair, and on darker skin the dark marks they leave can last far longer than the bumps themselves. Darker skin also has a higher risk of pigment changes after laser if the wrong settings are used. At Dermacy Clinic, Fitzpatrick skin types I to VI are assessed at consultation, a patch test comes first, and the 1064 nm wavelength is used to plan treatment on deeper skin.
How many sessions for the neck
The neck front or back usually needs 8 to 10 sessions, every 4 to 6 weeks. Facial and neck hair cycles faster than body hair, so the gaps are shorter than for the back or chest. Your own plan is set after the patch test.

FAQ
Will laser get rid of my razor bumps?
For most men it is the most effective long-term option, because it reduces the hairs that cause the bumps. Inflamed skin is settled first, and results vary from person to person.
Can I shave between laser sessions?
Yes. Shaving does not remove the root, which is what the laser targets. Avoid waxing, plucking and threading for four weeks before a session.
Is laser safe for Black skin?
Darker skin can be assessed and treated with the right wavelength and settings, but the risk of pigment change is higher if treatment is unsuitable. That is why a consultation and patch test always come first.
Will the dark marks go away?
Dark marks left by old bumps usually fade slowly once new bumps stop forming. They can be treated separately once the hair is under control.
