Yes, laser treatment is one of the most effective ways to reduce chronic ingrown hairs. It works by damaging the hair follicle so it produces thinner hair or stops growing altogether, which means there’s less hair available to curl back into the skin. Most people see significant improvement after a full course of six to eight sessions, with clinical studies showing up to an 86% average reduction in both hair count and ingrown bumps.
How Laser Treatment Stops Ingrown Hairs
Ingrown hairs happen when a hair curls back into the skin instead of growing outward. Coarse, curly hair is especially prone to this because the natural curl pattern directs the tip of the hair back toward the skin’s surface. Shaving makes things worse by creating a sharp edge on each hair strand.
Laser treatment targets the pigment (melanin) inside the hair shaft. The light energy converts to heat and damages the follicle itself, either destroying it or weakening it enough that the hair it produces is much finer and softer. Thinner hair is far less likely to pierce back into the skin. Even in cases where hair isn’t permanently eliminated, the regrowth is often too fine to cause ingrown problems. This is why laser is frequently recommended for people with a condition called pseudofolliculitis barbae, the medical term for chronic razor bumps, particularly when other treatments like topical creams and adjusted shaving techniques haven’t worked.
What Results Look Like
Expect modest results early on. Most people see about a 10% to 25% reduction in hair growth after the first session. The real payoff comes over the full treatment course of six to eight sessions, spaced about six to eight weeks apart. That timeline matters because hair grows in cycles, and the laser only affects follicles that are actively producing hair during each appointment.
A clinical study on patients with chronic ingrown hairs found an average 91% reduction in bumps and an 86.5% overall improvement in both hair and papule counts. Discoloration from old ingrown scars also improved by about 60%. After completing all sessions, many people go months or even years without significant new hair growth. Maintenance sessions may eventually be needed, since laser hair removal reduces growth long-term but isn’t always permanent.
Skin Tone and Laser Type Matter
Not every laser works safely on every skin tone, and this is especially important for people with darker skin, who are also more likely to struggle with ingrown hairs in the first place. Early laser technology was designed for light skin and dark hair. The laser targets melanin in the hair, but if your skin also contains a lot of melanin, some of that energy gets absorbed by the surrounding skin. This can cause burns, dark spots, or light patches.
The solution is a specific type of laser that operates at a longer wavelength (1,064 nm), commonly called an Nd:YAG laser. This wavelength bypasses the melanin in the skin’s surface and reaches deeper into the follicle. Studies specifically testing this laser on patients with medium brown to very dark skin confirmed it is both safe and effective for reducing ingrown hairs in those skin tones. If you have darker skin, ask your provider which laser they use before booking. If the answer is an Alexandrite laser (755 nm wavelength), that’s a red flag. It works well on fair skin but carries a higher risk of side effects on darker complexions.
Active Infections and Timing
If your ingrown hairs are mildly inflamed with small red bumps, treatment can generally proceed. However, if you have active infections, pus-filled bumps, or widespread inflammation, those need to be treated first. Lasering over severely infected skin increases the risk of complications and reduces effectiveness. Your provider will likely prescribe a short course of topical treatment to calm the area before starting laser sessions.
Aftercare Between Sessions
The weeks between laser sessions are when new ingrowns are most likely to form, especially as treated hairs shed and push through the skin. Gentle daily exfoliation with a soft washcloth or brush helps lift hairs that might otherwise get trapped. Products containing salicylic acid, applied once or twice daily after cleansing, reduce inflammation and help keep follicle openings clear so hairs can emerge normally. Avoid shaving too aggressively between sessions, and skip waxing entirely since it pulls the hair out by the root and removes the target the laser needs.
Laser vs. Electrolysis for Ingrown Hairs
Both laser and electrolysis can resolve chronic ingrowns, but they work differently and suit different situations. Laser covers large areas quickly, making it practical for the neck, bikini line, or legs. A full session might take minutes for a small area. Electrolysis destroys one follicle at a time with a tiny electric current, which means it’s slow but extremely precise. It’s the only method the FDA recognizes as truly permanent, and it works on all hair colors and skin types, including light or gray hair that laser can’t target.
For most people dealing with ingrown hairs over a broad area, laser is the faster and more practical option. Electrolysis makes more sense for small, stubborn patches or for hair colors that lack enough pigment for a laser to lock onto. Once electrolysis destroys a follicle, that follicle is done for good, with no maintenance sessions needed. Laser typically requires occasional touch-ups over time.
Cost Expectations
The average cost per laser session is around $697, according to the American Society of Plastic Surgeons. That figure varies widely depending on the size of the treatment area, your geographic location, and the provider’s qualifications. Treating a small area like the chin or upper lip costs considerably less per session than a full bikini line or back. With six to eight sessions typically needed, the total investment for a common ingrown-prone area often falls between $1,500 and $4,000. Some clinics offer package pricing that reduces the per-session cost. The price usually doesn’t include any topical prescriptions your provider might recommend for aftercare.
