Ingrown Hairs: Why They Keep Coming Back and How to Actually Stop Them

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.

Body Concerns

Exfoliating helps manage ingrown hairs. It doesn’t stop them. Laser does.

What It Is

An 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.

Why Patients Seek Treatment

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.

UNDERSTANDING THE SCIENCE

The hair is sharp, the follicle is curved, and repeated shaving makes both problems worse.

What Causes It

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.

02

Common Signs

Patients with ingrown hairs typically notice:

  • Small, raised bumps or papules along the bikini line, legs, underarms, face, or neck
  • Redness and inflammation around individual hair follicles
  • Itching or tenderness in affected areas
  • Dark spots or post-inflammatory hyperpigmentation from repeated irritation
  • Curved or coiled hairs visible beneath the skin surface
  • Occasional infected follicles with pus formation in chronic cases
03

Why It Changes Over Time

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.

04

How It's Commonly Addressed

Managing ingrown hairs ranges from topical maintenance to permanent reduction.

  • Topical exfoliants: AHAs and BHAs help keep follicle openings clear and reduce the likelihood of hairs curling back into the skin. Consistent use reduces frequency but doesn’t eliminate the problem.
  • Proper shaving technique: Shaving with the grain, using sharp blades, and using a single-blade razor all reduce the sharp angled tips that cause ingrown hairs. Helpful but not curative.
  • Laser hair removal: The only treatment that addresses ingrown hairs at the source. By reducing and eventually eliminating the hair follicle’s ability to produce hair, laser removes the problem entirely rather than managing it indefinitely. Patients with chronic ingrown hairs in treated areas consistently report complete resolution after a full treatment series.
  • Topical retinoids: Help with post-inflammatory hyperpigmentation and keep cell turnover moving in affected areas.

We Address The Hair At The Follicle Level — Not Just The Surface.

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.
