Razor bumps, known medically as pseudofolliculitis barbae (PFB), happen when shaved hairs curl back and grow into the skin, triggering inflammation, small bumps, and sometimes darkening or scarring. They're especially common in people with coarse or curly facial hair, and they can make daily shaving genuinely painful. The good news is that PFB is usually manageable with the right combination of technique changes and treatment.
Why razor bumps happen
When a curly hair is cut, the sharp tip can curve back and re-enter the skin, or grow sideways into the follicle wall. Your body treats that hair like an irritant, which is what causes the red, tender bumps. Shaving too closely tends to make it worse, because it leaves a sharper tip below the skin surface.
Shaving changes that help
- Shave less closely: avoid stretching the skin for the closest possible cut
- Shave in the direction the hair grows, not against it
- Use a single- or double-blade razor rather than a many-blade one, or an electric trimmer that leaves slight stubble
- Soften the beard first with warm water and a lubricating gel, and use a fresh blade
- Consider shaving less often, giving the skin time to recover
Treatments a dermatologist may consider
- Topical treatments to reduce inflammation and clear bumps
- Topical retinoids to help with follicle clogging and skin texture over time
- Treatments to address dark marks left behind, when appropriate
- For some people, longer-term hair-reduction approaches discussed on a case-by-case basis
Razor bumps and shaving waivers
For service members, PFB is the most common medical reason to seek a shaving waiver. A dermatologist can evaluate the condition and provide documentation, though the waiver itself is granted through your military medical and command chain. You can read more on our shaving-waiver and military shaving-waiver pages.
How an online evaluation works
At DocBright, you upload clear photos of the affected areas and a short history of how shaving affects your skin, and a board-certified dermatologist reviews your case. When appropriate, they provide a treatment plan and prescription and, for service members, documentation of the evaluation. Your dermatologist will tell you if anything needs an in-person look.
