What is Ingrown Hair & How to Remove Ingrown Hair

An ingrown hair happens when a cut or removed hair curls back and grows into the skin instead of upward and out. It's common, usually harmless, and almost always tied to how hair is being removed — which means it's also one of the more preventable skin irritations out there.

Why it happens

When hair is cut very close to the skin — through shaving, waxing, or tweezing — the sharpened tip can curl back on itself and pierce the surrounding skin instead of growing outward. This triggers a small inflammatory reaction: redness, a raised bump, sometimes a visible trapped hair underneath.

It's more common in people with curly or coarse hair, since curved hair is naturally more prone to growing back into the skin after being cut. Anyone can get one, though — the underlying cause is mechanical, not just a hair-type issue.

Safe ways to treat one at home

Most ingrown hairs resolve on their own within a few days to a couple of weeks without any intervention. If you want to speed things along:

• Warm compress. Apply a warm, damp washcloth to the area for a few minutes — this softens skin and can help the trapped hair work its way to the surface.
• Gentle exfoliation. A soft washcloth or mild exfoliating scrub in circular motions can help lift the hair and clear dead skin blocking the follicle.
• Leave it alone otherwise. Don't pick, squeeze, or dig at it with tweezers or a needle unless the hair is already visible at the surface — doing so risks infection and scarring.

When to see a doctor

Most ingrown hairs aren't a medical concern, but see a professional if you notice signs of infection: increasing pain, spreading redness, pus, or a hard lump that doesn't improve after a couple of weeks. Recurring, severe ingrown hairs (sometimes called pseudofolliculitis) can also benefit from a dermatologist's input on longer-term prevention.

Preventing future ingrown hairs

• Shave in the direction hair grows, not against it
• Use a sharp, clean blade — dull blades cause more skin trauma and are more likely to snag and cut hair unevenly
• Wet skin and hair thoroughly before shaving, with a proper shaving gel or cream
• Exfoliate regularly between hair removal sessions to prevent dead skin from trapping new growth
• Consider reducing shaving/waxing frequency, or exploring longer-term hair reduction methods, if ingrown hairs are a recurring problem for you

The bottom line

Ingrown hairs are common, usually minor, and largely a byproduct of how hair is removed rather than anything more serious. Gentle at-home care resolves most cases, and better shaving technique prevents a lot of repeat occurrences — persistent or infected cases are the signal to involve a professional rather than keep treating it yourself.
