Ingrown hairs form when sharp, curved hairs re-enter the skin after shaving or waxing. Laser hair removal is the only treatment that addresses the cause rather than the symptom.
get startedAn ingrown hair occurs when a hair that has been cut or removed grows back and curves into the skin rather than exiting the follicle normally. The body responds to the hair as a foreign object, creating inflammation, redness, and sometimes a small infected papule.
Ingrown hairs most commonly affect areas that are regularly shaved or waxed — the bikini line, legs, underarms, face, and neck. They are more common in patients with naturally coarse or curly hair, because the curved follicle makes it more likely for regrowth to change direction.
Patients seek treatment when chronic ingrown hairs are affecting how their skin looks and feels — particularly in high-visibility or sensitive areas like the bikini line, underarms, legs, or neck. The bumps, dark spots, and scarring that ingrown hairs leave are often more distressing than the ingrown itself, and topical approaches alone rarely keep pace with the problem.
Ingrown hairs develop when a hair fails to exit the follicle normally and instead curves back into the skin or grows sideways beneath the surface.
Hair removal technique: Shaving creates a sharp, angled tip on the cut hair shaft. When that sharp tip contacts the follicle wall or surrounding skin as it grows, it can penetrate and cause an inflammatory response. Waxing and tweezing can leave hair fragments below the surface that curve as they regrow.
Follicle anatomy: Naturally curly or coarse hair is more prone to ingrown hairs because the curved follicle channel makes it harder for the hair to grow straight out. This is why ingrown hairs disproportionately affect patients with coarser hair textures.
Dead cell buildup: When dead skin cells accumulate over the follicle opening, growing hairs have no clear exit path and turn inward instead.
Patients with ingrown hairs typically notice:
Ingrown hairs don’t follow an aging pattern the way most skin concerns do — they’re driven by hair removal habits rather than biological age. However, the cumulative damage from years of repeated ingrown hairs does worsen over time: chronic inflammation leaves post-inflammatory hyperpigmentation, scarring in the follicle can distort regrowth further, and skin that has been repeatedly irritated becomes more reactive.
Patients who have managed ingrown hairs with topical treatments for years often reach a point where the hyperpigmentation from repeated inflammation becomes the primary concern — layered on top of the ongoing ingrown hair cycle.
Managing ingrown hairs ranges from topical maintenance to permanent reduction.
At CAMI, we recommend laser hair removal for patients with chronic ingrown hairs in treated areas — particularly the bikini line, legs, and underarms, where the combination of coarse hair and repeated shaving creates the most persistent problems. Laser doesn’t manage the ingrown hair cycle; it ends it.
We assess the patient’s hair type, skin tone, and pattern of affected areas before recommending a treatment protocol. Results develop over a series of sessions, with most patients experiencing significant reduction in ingrown hairs after the first two to three treatments.

Care guided by experience, precision, and a deep understanding of natural beauty.
