Pseudofolliculitis Barbae (Razor Bumps)
Key takeaways
Pseudofolliculitis barbae (PFB), often called razor bumps, happens when shaved hairs curve back into the skin and trigger inflammation.
It is especially common in people with tightly curled or coiled hair and is one of the most common skin conditions affecting Black men who shave.
In skin of color, razor bumps may not look red. They often appear as skin-colored, dark brown, or hyperpigmented bumps, and the dark marks left behind can be more distressing than the bumps themselves.
The most important first step is reducing or stopping close shaving so the skin has time to heal.
Treatment is not just about clearing bumps. It also involves preventing dark spots, scarring, and long-term skin texture changes.
If your job requires shaving, PFB is a legitimate medical condition—and in some cases, a dermatologist can help document the need for a shaving waiver or alternative grooming plan.
What Is Pseudofolliculitis Barbae?
Pseudofolliculitis barbae, or PFB, is a chronic inflammatory skin condition that develops when shaved hairs grow back into the skin instead of growing outward normally. This most often happens after shaving the beard area, which is why many people know it as razor bumps.
When a hair curves back into the skin—or when a very closely cut hair pierces the skin as it grows out—the body treats it like a foreign object. That triggers inflammation, which leads to:
firm bumps
tender or itchy papules
pus-filled bumps in some cases
dark marks after the bumps heal
PFB most commonly affects the beard and neck area, but it can also occur anywhere hair is removed by shaving, waxing, or plucking, including the:
bikini area
underarms
legs
scalp or back of the neck in some people
PFB is not an infection, and it is not caused by poor hygiene. It is fundamentally a problem of hair shape, shaving technique, and skin response.

A few things worth knowing
PFB affects an estimated 45–83% of Black men who shave, making it one of the most common dermatologic conditions in skin of color.
It can also affect Hispanic men, women who remove body hair, and anyone with tightly curled hair.
The condition is driven more by hair texture and growth pattern than by race itself—but because tightly curled hair is more common in certain populations, PFB disproportionately affects Black and Brown patients.
It can have major occupational consequences, especially in workplaces or military settings that require a clean-shaven appearance.
What Does PFB Look Like?
PFB usually appears as small bumps around hair follicles in areas where hair has been shaved or closely cut.
Common symptoms
People with PFB may notice:
firm bumps in the beard or neck area
itching, tenderness, or burning
small pustules
visible ingrown hairs
dark spots after the bumps heal
raised scars in chronic or severe cases
What it often looks like
Early or active PFB
small follicular bumps
tender papules
occasional pustules
irritation after shaving
More chronic PFB
clusters of persistent bumps
rough skin texture
visible dark marks from older lesions
thickened or scarred areas in severe cases
In deeper skin tones
PFB may not look bright red. Instead, bumps are often:
skin-colored
dark brown
hyperpigmented
easier to feel than to see at first
That difference matters, because PFB can look less “inflamed” than it really is on darker skin tones.
Understanding How PFB Develops
PFB happens because of the way shaved hair interacts with the skin.
The basic problem: the hair grows back into the skin
After shaving, especially with a very close shave, the cut tip of the hair can behave in two ways:
1. The hair exits the skin and then curls back in
This is often called extrafollicular penetration. The hair leaves the follicle, curves, and re-enters the nearby skin.
2. The sharpened hair tip pierces the follicle wall before it exits
This is often called transfollicular penetration. Instead of growing out cleanly, the hair penetrates the wall of the follicle itself.
In both cases, the body reacts to the hair as if it does not belong there. That triggers an inflammatory response, leading to the bumps and discomfort people associate with razor bumps.
Why tightly curled hair is at higher risk
Tightly curled or coiled hair has a natural tendency to curve back toward the skin. The closer the shave, the easier it is for that sharpened hair tip to re-enter the skin instead of growing outward.
This is why PFB is especially common in people with:
curly beard hair
tightly coiled facial hair
coarse hair that grows at an angle
Genetics may also play a role
PFB is not just about technique. There is evidence that genetic factors affecting hair follicle structure may increase risk in some people. That helps explain why some individuals develop severe PFB even when they are trying to shave carefully.

Why PFB deserves special attention in skin of color
PFB is one of the clearest examples of why dermatology cannot rely only on “classic” textbook images based on lighter skin.
In skin of color, PFB often behaves differently in ways that matter:
the bumps may not look obviously red
the dark spots left behind may be more visible and longer lasting
the risk of keloid or hypertrophic scarring is higher in some patients
workplace shaving expectations may disproportionately harm people who are biologically more
prone to the condition
This is not just a cosmetic inconvenience. For many patients, PFB is a chronic inflammatory disorder with emotional, social, and professional consequences.
In darker skin tones, the dark marks may become the biggest problem
One of the most frustrating parts of PFB in skin of color is post-inflammatory hyperpigmentation (PIH)— the dark spots left behind after a bump heals.
These marks can:
last for months
sometimes outlast the active bumps
make the beard area look uneven or scarred even after inflammation is better
For many patients, the bumps are temporary—but the pigment change is what lingers.
Scarring risk matters more
Chronic PFB can lead to:
raised scars
hypertrophic scarring
keloid formation in susceptible individuals
That risk is especially important in people with deeper skin tones, because keloids are more common in populations of African descent and can be difficult to treat once established.
PFB can be confused with acne
PFB is often mistaken for acne, but they are not the same thing.
Acne is primarily a disorder of clogged pores and inflammation
PFB is primarily a disorder of ingrown hairs and shaving-related trauma
The distinction matters because the treatment plan is different. Someone treating PFB like ordinary acne may keep missing the most important trigger: the way the hair is being removed.
Why PFB Matters Beyond the Skin
PFB can be physically uncomfortable, but its impact often extends much further.
It can affect confidence and self-image
The beard and neck are highly visible areas. Chronic bumps, dark spots, and scarring can affect:
self-confidence
professional appearance
dating and social comfort
willingness to be photographed
overall quality of life
It can create a workplace dilemma
Many jobs—especially the military, law enforcement, and some customer-facing workplaces—have
historically expected a clean-shaven appearance.
For someone with PFB, that creates a painful choice:
keep shaving and worsen the condition
or stop shaving and risk professional pressure, stigma, or the need for formal documentation
That burden has disproportionately affected Black men for decades because they are the group most likely to be biologically predisposed to PFB.
It can become a cycle of inflammation and damage
Without intervention, repeated close shaving can lead to:
more ingrown hairs
more inflammation
more dark spots
more scarring
a beard area that never fully settles down
That is why PFB treatment has to focus on breaking the cycle, not just calming a few bumps.
Treatment Goals
PFB treatment usually has three goals:
1. Stop the cycle of ingrown hairs
This means changing how hair is removed—or pausing hair removal entirely.
2. Reduce active inflammation
This helps calm bumps, tenderness, and secondary irritation.
3. Prevent long-term complications
This includes preventing:
post-inflammatory hyperpigmentation
thickened scars
keloids
chronic skin texture changes
The Most Important First Step: Reduce or Stop Close Shaving
If possible, the single most effective initial treatment is stopping shaving for at least several weeks— often around 8 weeks if the situation allows.
This gives embedded hairs time to grow out and allows inflammation to calm down.
If completely stopping is not realistic, the next best option is usually to avoid shaving down to the skin. That may mean switching from a manual razor to an electric trimmer that leaves a small amount of stubble rather than cutting the hair below the skin surface.
This is one of the most important counseling points in PFB:
The closer the shave, the higher the risk of razor bumps.
Treatment Options
-
Best options for many patients with PFB
stop shaving temporarily if possible
use an electric clipper or trimmer instead of a close manual razor
leave hair slightly longer rather than shaving to the skin
avoid plucking ingrown hairs
avoid waxing if it worsens the problem
If you must use a manual razor
choose a single-blade razor rather than a multi-blade razor
shave with the grain, not against it
avoid pulling the skin taut
use short, gentle strokes
avoid repeated passes over the same area
-
Benzoyl peroxide
Benzoyl peroxide can help reduce inflammation and bacterial overgrowth around irritated follicles. It is often used as a wash or gel.
Topical clindamycin
Topical clindamycin may be used when pustules or inflammatory bumps are prominent.
Combination clindamycin + benzoyl peroxide
This combination is often helpful because it addresses both inflammation and follicular irritation.
Topical retinoids
Retinoids such as tretinoin, adapalene, or tazarotene can help normalize skin cell turnover and reduce the tendency for hairs to become trapped.
Short-term topical steroids
Low-potency topical steroids may be used briefly during flares to calm inflammation, but they are not ideal as a long-term strategy—especially on the face—because of the risk of skin thinning or pigment change.
Skin of Color Treatment Considerations
Treating the bumps is only half the job
For patients with deeper skin tones, PFB treatment often has to address two problems at once:
the active razor bumps
the dark marks and scarring left behind
If you only treat the active bumps but ignore the post-inflammatory hyperpigmentation, patients may still feel like the condition is not improving.
Dark spot treatment may be part of the plan
Depending on the situation, a dermatologist may consider options such as:
azelaic acid
retinoids
hydroquinone
carefully selected combination therapies
daily sunscreen to keep existing dark spots from getting darker
The exact approach depends on skin sensitivity, severity, and whether the person is still actively inflamed.
Laser selection matters in skin of color
Laser hair removal can be one of the most effective long-term treatments for PFB—but not every laser is equally safe for darker skin tones.
For many patients with Fitzpatrick skin types IV–VI, the long-pulsed Nd:YAG laser is often considered the safest option because it lowers the risk of burns and unwanted pigment changes compared with some other devices.
That is one reason PFB patients with skin of color should ideally see a dermatologist or laser specialist who is experienced in treating darker skin safely.
Build a Routine
If you are actively flaring
Morning
Wash the area with a gentle cleanser or a benzoyl peroxide wash if tolerated
Apply prescribed treatment if you have one
Use a light, non-comedogenic moisturizer if the area is dry
Apply broad-spectrum sunscreen if the area is exposed, especially if you are trying to fade dark marks
Evening
Cleanse gently
Apply any retinoid or prescription topical treatment recommended by your dermatologist
Moisturize if needed
How to Shave More Safely If You Have PFB
-
soften the beard with warm water or a warm washcloth
use a shaving cream or gel rather than dry shaving
avoid rushing through the shave
-
shave in the direction of hair growth
avoid stretching the skin
use light pressure
avoid going over the same spot multiple times
consider a single-blade razor or, even better, an electric trimmer that leaves hair slightly above the skin
-
rinse gently
avoid picking or squeezing bumps
apply a soothing, non-irritating moisturizer if needed
continue treatment if your dermatologist has prescribed one
Common Mistakes That Make PFB Worse
1. Shaving too closely
This is the biggest one. A very close shave increases the chance that the cut hair will grow back into the skin.
2. Using multi-blade razors
Multi-blade razors can cut hair below the skin surface, which may increase the risk of ingrown hairs in susceptible people.
3. Shaving against the grain
This gives a closer shave—but often at the cost of more irritation and more ingrown hairs.
4. Picking at the bumps
Picking can worsen inflammation, increase infection risk, and make dark spots or scars much more likely.
5. Treating it like acne without addressing shaving habits
Acne products alone will not solve PFB if the same hair-removal trigger is happening every few days.
6. Ignoring dark spots until they become long-standing
For skin of color patients, pigment changes deserve attention early, not just after the bumps are gone.
When to See a Dermatologist
It is worth seeing a dermatologist if:
razor bumps are not improving after several weeks of shaving changes
you are developing persistent dark spots
you are seeing raised scars or keloid-like bumps
the beard area is painful, draining, or showing signs of infection
you are not sure whether the bumps are PFB, acne, bacterial folliculitis, or another condition
your job requires shaving and you need help with documentation or a medical waiver
you want to discuss laser hair removal as a longer-term solution
the condition is affecting your confidence, mental health, or quality of life
For patients with skin of color, early dermatology care can be especially helpful because it may reduce the risk of permanent pigment change and scarring.
FAQ
-
No. PFB is caused by ingrown hairs and shaving-related inflammation, while acne is primarily a disorder of clogged pores and inflammation. They can look similar, but they are not the same condition.
-
Technique matters, but hair texture and growth pattern matter too. People with tightly curled hair can still get PFB even when they are trying to do everything “right.”
-
Not necessarily. But many people need to change how they shave, reduce how closely they shave, or consider alternative hair-removal strategies to keep the condition under control.
-
They often improve over time, but in skin of color they can last for months. The best way to prevent them is to control the inflammation early and avoid picking at the bumps.
-
For many people with persistent PFB, yes—especially if shaving is required for work or if the condition keeps recurring. It is often one of the most effective long-term options when performed by someone experienced in treating darker skin tones.
