Ingrown Hair (Pseudofolliculitis Barbae) - Symptoms, Causes & Treatment
Medically reviewed by Dr. Anand S. Urhekar, MD, MD Pathology, Clinical Advisor · Last updated July 2026
Inflammation caused by a hair curling back or growing sideways into the skin instead of out of the follicle, producing tender red bumps, pustules and sometimes dark marks or keloids. It is especially common on the beard area, neck, bikini line and legs, and disproportionately affects people with tightly curled hair.

Quick Answer
An ingrown hair occurs when a shaved or waxed hair re-enters the skin, causing a tender red bump or pustule. It is most common with tightly curled hair on the beard, neck and bikini line. Prevention is the main treatment: shave less closely with a single-blade razor in the direction of growth, exfoliate gently, and consider laser hair reduction for persistent cases.
Symptoms
- Tender red bumps or pustules after shaving or waxing
- Visible hair looped under the skin surface
- Itch and soreness
- Dark marks (post-inflammatory hyperpigmentation) after healing
- Keloid scarring on the neck in severe cases
Causes & Risk Factors
- Tightly curled hair re-entering the skin
- Close shaving, shaving against the grain, multi-blade razors
- Waxing, plucking and tight clothing
- Dead skin blocking the follicle opening
Treatment & Management
- Stop shaving temporarily to let lesions settle
- Single-blade or electric razor, shaving with the grain, no stretching the skin
- Gentle chemical exfoliation with salicylic or glycolic acid
- Topical antibiotic or short-term steroid for inflamed bumps
- Laser hair reduction as the most durable long-term solution
When to See a Doctor
See a doctor if bumps are large, painful, filled with pus, spreading, or if you are developing thick raised scars on the neck — early treatment prevents permanent keloids.
Frequently Asked Questions
Should I dig the hair out?
No. Tweezing or digging with a needle drives bacteria deeper and causes scarring and dark marks. Let the inflammation settle; a hair loop lying visibly on the surface can be gently lifted with a sterile needle by a clinician.
Does laser hair removal help razor bumps?
Yes — reducing hair density is the most effective long-term treatment for recurrent pseudofolliculitis barbae, and modern Nd:YAG lasers are safe for darker skin types when used by an experienced operator.
