Getting rid of an ingrown hair usually comes down to three things: coaxing the trapped hair free, calming the inflammation around it, and changing whatever caused it to grow inward in the first place. Most ingrown hairs resolve on their own within a week or two if you stop shaving the area and keep it clean, but stubborn or recurring ones call for targeted topical treatments, smarter hair-removal habits, or in chronic cases, laser hair removal. The condition has a clinical name, pseudofolliculitis barbae (PFB) when it strikes the beard area, and it affects some people far more than others for reasons that go deeper than grooming habits.
What Makes a Hair Grow Inward
An ingrown hair forms when a hair shaft, instead of growing straight out of the follicle, curls back and re-enters the skin or gets trapped beneath the surface. The body treats the re-entering hair like a foreign object and mounts an inflammatory response, producing the familiar red, tender bump that can fill with pus. There are two routes this happens: the hair can exit the follicle and curve back in (extrafollicular penetration), or a freshly cut hair can pierce the follicle wall before it even reaches the surface (transfollicular penetration). Close shaving sharpens the tip of the hair, making either route more likely.
Curly or coiled hair is far more prone to this because the natural curve of the shaft directs it back toward the skin. A genetic component makes some people especially vulnerable. Researchers have identified a specific mutation in keratin 75, a protein in the hair follicle’s inner lining, that appeared in about 36% of people with chronic ingrown hairs compared with 9% of unaffected controls. That weakened follicle structure, combined with tightly curled hair and close shaving, creates a perfect storm.
Treating an Existing Ingrown Hair
If you have one or two angry bumps, the first step is to stop removing hair in that area. Continued shaving over an inflamed ingrown only drives the hair deeper and risks scarring. Apply a warm, damp washcloth to the bump for five to ten minutes a few times a day. The heat softens the skin and can help the trapped hair work its way to the surface. Once you can see the hair loop above the skin, you can gently lift it out with a sterile needle or clean tweezers. Do not dig into the skin to find a hair that is not yet visible; that invites infection and scarring.
Resist the urge to squeeze an ingrown hair like a pimple. The contents of the bump are not just pus but also inflammatory debris surrounding the embedded hair shaft, and squeezing can push bacteria deeper or rupture the follicle wall beneath the surface. If a bump is very painful, swollen, or develops a dark crust, see a doctor. A short course of a topical antibiotic or a minor in-office procedure to release the hair is far less likely to leave a mark than aggressive self-treatment.
Rethinking How You Remove Hair
Prevention matters more than treatment for people who get ingrown hairs repeatedly. The most definitive way to stop them is to stop shaving closely, or to stop shaving altogether. That is not always practical, but it is worth knowing that trimming hair to about one millimeter with an electric clipper rather than shaving it flush dramatically reduces the number of ingrown bumps for most people.
If you do shave with a blade, conventional advice has long been to shave with the grain (in the direction of hair growth) and to use a single-blade razor rather than a multi-blade cartridge. The logic is that multi-blade razors cut the hair below the skin surface, giving it a sharper tip and a head start on burrowing back in. However, the evidence is more nuanced than the advice suggests. One study found that men who shaved against the grain actually had lower papule counts, and another found that multi-blade razors did not worsen ingrown hairs when used with a preshave cleanser and a postshave lotion.1Dermatologic Clinics. Pseudofolliculitis Barbae and Acne Keloidalis Nuchae That does not mean every person should switch to against-the-grain shaving, but it does mean the old rules are not universal. What consistently helps is avoiding multiple passes over the same skin, shaving after a warm shower when hair is softer, and using a sharp blade rather than a dull one.
For areas like the bikini line and underarms, where skin folds and friction compound the problem, consider switching to an electric trimmer entirely. Waxing and epilating pull the hair from the root, which sounds like it should solve the re-entry problem, but the regrown hair can still curl beneath the surface. Waxing in particular carries a risk of skin irritation, folliculitis, and ingrown hairs.2Anais Brasileiros de Dermatologia. Polycystic ovary syndrome: a dermatologic approach If you wax, exfoliating the area gently between sessions with a soft cloth or mild chemical exfoliant can help new hairs find their way out.
Topical Treatments That Work
Several over-the-counter and prescription products can both treat existing ingrown hairs and prevent new ones. The best-studied options fall into two categories: exfoliants that keep the skin surface thin enough for hairs to exit cleanly, and retinoids that change how skin cells turn over around the follicle.
Chemical Exfoliants
Glycolic acid and salicylic acid are the two most commonly recommended chemical exfoliants for ingrown hairs. In a placebo-controlled trial, an 8% glycolic acid lotion applied after shaving reduced the number of pustules and papules within two weeks.3JAAD Reviews. Insights into the role of grooming modifications and preventative approaches in Pseudofolliculitis barbae: A narrative review of hair removal practices Glycolic acid appears to work partly by disrupting bonds in the hair shaft itself, causing the hair to grow straighter so it is less likely to curl back into the skin. Salicylic acid works differently: it is oil-soluble, so it penetrates into clogged pores and follicles to dissolve the buildup of dead skin cells that traps hairs beneath the surface. Products in the 1–2% salicylic acid range are widely available in acne washes and toners. Applying one of these to ingrown-prone areas a few times a week, even on days you do not shave, can make a noticeable difference over the course of a month.
Retinoids
Tretinoin, the prescription retinoid best known for treating acne and signs of aging, also has solid evidence behind it for ingrown hairs. In a study of 38 men with beard-area ingrown hairs, daily application of a 0.05% tretinoin solution produced good to excellent results within eight weeks, with the strongest effects seen in earlier, less severe cases.4JAMA Dermatology. Pseudofolliculitis of the Beard and Topically Applied Tretinoin Tretinoin thins the outermost layer of skin and speeds up cell turnover, which prevents dead cells from piling up over the follicle opening. Over-the-counter retinol products (a weaker, non-prescription form) may offer a milder version of this effect, though the clinical data specifically supports prescription-strength tretinoin. Because retinoids make skin more sensitive to the sun, daily sunscreen becomes non-negotiable if you use one on exposed areas.
When Laser Hair Removal Makes Sense
For people who get chronic, recurring ingrown hairs despite adjusting their shaving routine and using topical treatments, laser hair removal targets the root cause: the hair itself. By destroying the follicle’s ability to produce hair, laser treatment eliminates the possibility of that hair growing back into the skin. Multiple sessions are needed because hair grows in cycles, and the laser only works on follicles in their active growth phase.
The type of laser matters, especially for darker skin tones. Older laser systems (like the alexandrite) work by targeting melanin in the hair, but because darker skin also contains more melanin, those lasers carry a higher risk of burns and discoloration in people with medium to dark skin. The long-pulse Nd:YAG laser was developed to address this problem. In a study of 26 patients with dark skin (types IV through VI on the Fitzpatrick scale) who had ingrown hairs that did not respond to other treatments, the Nd:YAG laser cut the average number of bumps roughly in half on the treated side compared to the untreated side.5PubMed Central. Treatment of pseudofolliculitis barbae in very dark skin with a long pulse Nd:YAG laser That is not a cure in one session, but over a course of treatments, many people see a dramatic and lasting reduction.
Laser treatment is the most expensive option, and it is not always covered by insurance unless a doctor documents it as medically necessary for chronic pseudofolliculitis. But for someone who has been battling painful, scarring ingrown hairs for years, it can be the only thing that truly resolves the problem rather than just managing it.
Who Gets Ingrown Hairs Most and Why
Ingrown hairs can affect anyone who removes hair, but they are overwhelmingly more common in people with tightly curled hair. Black men are disproportionately affected: pseudofolliculitis barbae is one of the most common dermatologic conditions in this population, driven by the natural curl pattern of the hair combined with the genetic variant in keratin 75 discussed earlier.6The Journal of the American Board of Family Medicine. Ethnic Equity Implications in the Management of Pseudofolliculitis Barbae The curly hair and the weakened follicle lining work together to increase risk far beyond what either factor causes alone.7British Journal of Dermatology. Pseudofolliculitis cutis: a vexing disorder of hair growth
People of Hispanic, Middle Eastern, and South Asian descent are also more susceptible than those with straight hair, though the research literature focuses heavily on Black men because the condition is so prevalent and so consequential in that group. Women get ingrown hairs too, particularly in the bikini area, underarms, and legs. Hormonal conditions that increase androgen levels, such as polycystic ovary syndrome, can convert fine body hair into thicker, coarser terminal hair in areas like the face, neck, and chest, which then becomes more likely to grow inward after removal.2Anais Brasileiros de Dermatologia. Polycystic ovary syndrome: a dermatologic approach
Complications Worth Taking Seriously
Most ingrown hairs are annoying but harmless. However, chronic or poorly managed ingrown hairs can lead to real skin damage. The three main complications to watch for are post-inflammatory hyperpigmentation, bacterial infection, and keloid scarring.
Post-inflammatory hyperpigmentation (dark spots left behind after the bump heals) is especially common in darker skin tones. The inflammation from each ingrown hair triggers excess melanin production, and those marks can persist for months or even years after the bump itself is gone. Sunscreen, gentle exfoliation, and topical treatments like vitamin C or azelaic acid can help fade them, but prevention of the ingrown hair in the first place is the most effective strategy.
Bacterial infection turns an ingrown hair into something more serious. If bacteria get into the broken skin around the bump, you can end up with a painful abscess that requires antibiotics or drainage. Signs of infection include increasing pain, expanding redness, warmth, and yellow or green discharge. Do not wait on these symptoms; see a healthcare provider promptly.
Keloid scarring is the most concerning long-term complication. Some people, particularly those with darker skin, are genetically prone to forming thick, raised scars (keloids) at sites of skin injury. Chronic ingrown hairs that are repeatedly inflamed can trigger keloid formation, especially on the back of the neck (a condition called acne keloidalis nuchae). Treatment of established keloids is difficult and can itself carry a risk of further scarring.8American Journal of Clinical Dermatology. Follicular and scarring disorders in skin of color: presentation and management This is one of the strongest arguments for treating chronic ingrown hairs aggressively rather than just tolerating them.
Workplace Grooming Policies and the Ingrown Hair Burden
One of the more frustrating dimensions of this problem is that the people most susceptible to chronic ingrown hairs are often the ones most pressured to shave. Military grooming standards, law enforcement dress codes, and corporate “clean-shaven” policies force many men, disproportionately Black men, to choose between their career and their skin health. The U.S. military has recognized pseudofolliculitis barbae as a significant issue for service members with curly facial hair, and severe cases can warrant official shaving waivers or referrals for laser therapy.9Military Medicine. Pseudofolliculitis Barbae in the U.S. Military, a Review
Outside the military, the picture is less accommodating. Many Black men have been forced to comply with clean-shaven policies in the civilian workforce with no formal pathway to request medical accommodation.6The Journal of the American Board of Family Medicine. Ethnic Equity Implications in the Management of Pseudofolliculitis Barbae If you are in this situation, a letter from a dermatologist documenting your condition can be powerful. Pseudofolliculitis barbae is a recognized medical diagnosis, not a cosmetic complaint, and many employers will grant grooming exceptions once they understand it is a chronic inflammatory skin disease exacerbated by the very grooming standard they enforce.
What an Ingrown Hair Is Not
Not every bump in a shaved area is an ingrown hair, and misidentifying the problem leads to the wrong treatment. A few conditions commonly get confused with ingrown hairs:
- Folliculitis: A bacterial or fungal infection of the hair follicle. It looks similar to ingrown hairs but affects follicles that are not necessarily trapped under the skin. Folliculitis often responds to antibacterial or antifungal washes rather than the exfoliation-focused treatments that help ingrown hairs.
- Hidradenitis suppurativa: A chronic inflammatory condition that causes painful lumps, often in the groin, armpits, and under the breasts. It involves deeper structures than a typical ingrown hair and tends to recur in the same locations with tunneling under the skin. If you have recurring painful nodules in skin folds that drain and scar, this is a different condition that requires different management.
- Contact dermatitis: An allergic or irritant reaction to a shaving product. The rash is usually more widespread and itchy than the focal bumps of ingrown hairs, and switching products resolves it.
If over-the-counter treatments and better shaving habits have not improved your bumps within four to six weeks, or if the bumps are large, deeply painful, or tunneling under the skin, see a dermatologist. Chronic pseudofolliculitis that does not respond to conservative measures may benefit from prescription-strength retinoids, combination antibiotic regimens, or a referral for laser hair removal.
The Emotional Weight of Chronic Ingrown Hairs
Ingrown hairs are easy to dismiss as a minor nuisance, but for people who deal with them chronically, particularly on visible areas like the face and neck, the psychological toll is real. Visible skin lesions in the beard area can erode self-esteem and body image, and the persistent bumps sometimes trigger compulsive behaviors like skin picking, which only makes the scarring worse.10PubMed Central. Psychiatric Comorbidities in Pseudofolliculitis Barbae: A Cross-Sectional Study of the All of Us Database People with chronic PFB report anxiety about their appearance in professional and social settings, and the condition can feel especially isolating because it is so rarely discussed publicly. If ingrown hairs are affecting your mental health or daily functioning, that is reason enough to pursue aggressive treatment. It is also worth knowing that you are far from alone: this is one of the most common skin conditions in people with curly hair, and dermatologists see it constantly.
Building a Prevention Routine That Sticks
The treatments and strategies above work best when combined into a consistent routine rather than applied in isolation. For someone who shaves regularly and is prone to ingrown hairs, a practical daily and weekly routine looks something like this:
- Before shaving: Wash the area with warm water and a gentle cleanser to soften the hair and clear dead skin from follicle openings. A pre-shave oil can add an extra layer of lubrication.
- During shaving: Use a sharp, clean blade. Make single passes with light pressure. Rinse the blade after every stroke. Experiment with shaving direction; if with-the-grain still leaves you bumpy, a careful against-the-grain pass with proper lubrication may actually work better for your skin.
- After shaving: Apply a glycolic acid or salicylic acid lotion to the shaved area. Avoid heavy, occlusive moisturizers immediately after shaving, as they can seal bacteria into freshly opened follicles. An alcohol-free aftershave with anti-inflammatory ingredients (aloe, niacinamide) can reduce immediate irritation.
- On non-shaving days: Use a gentle chemical exfoliant two to three times per week to prevent dead skin from accumulating over follicle openings. If you use a prescription retinoid, apply it on alternating nights.
Consistency matters more than perfection. Skipping one day of exfoliation will not undo your progress, but abandoning the routine entirely for two weeks can restart the cycle. For body areas like the bikini line, wearing looser-fitting underwear and breathable fabrics between shaves reduces the friction that pushes regrowing hairs sideways into the skin. Cotton or moisture-wicking materials are worth the switch if you are prone to ingrown hairs in areas where clothing sits tightly against the skin.
