17722 Ingrown Hair

Overview

An ingrown hair is a hair that curls back or grows sideways into the skin instead of coming out straight. It usually looks like a small red bump, sometimes with a hair visible underneath. It can feel sore or itchy, and it may fill with clear fluid or pus. Ingrown hairs are common and are usually harmless.

Yes, ingrown hairs are very common. They affect people of all skin types, but they are more common in people with coarse or curly hair. Anyone who removes hair from the face, neck, legs, armpits, or bikini area can get one.

Ingrown hairs can affect anyone who shaves, waxes, or plucks hair—especially teenagers just starting to shave and adults who remove hair regularly. People with tight, curly hair are at higher risk, and men often get them on the face and neck after shaving.

Symptoms

Common symptoms

• A small, red or dark bump on the skin
• Tenderness or pain at the spot
• Itching or a tickling feeling
• A visible hair trapped under the skin
• A small round swelling or a pus-filled blister that looks like a pimple

Symptoms in children

• Ingrown hairs are less common in young children, but they can appear in teenagers who start shaving.
• The most common areas are the face, neck, or legs.
• Children may feel embarrassed or worried about the bumps, so a calm explanation helps.

Symptoms in older adults

• Older adults may get ingrown hairs after shaving, but their skin can be more fragile and slower to heal.
• Ingrown hairs may be mistaken for other skin problems, so a doctor's look can be helpful.
• Reduced hair growth with age can make ingrown hairs less common, but they can still happen.

Causes

Main causes

• Shaving, waxing, or tweezing pulls the hair out, and when it regrows, it can curl into the skin.
• Cutting hair too close leaves a sharp tip that can pierce the skin.
• Dead skin cells block the hair follicle, forcing the hair to grow sideways.
• Tight clothing rubs against the skin and can push hairs back into the skin.

Risk factors

• Naturally curly or coarse hair
• Shaving with a dull razor or shaving too close
• Shaving without warm water or shaving cream
• Pulling the skin tight while shaving
• Wearing tight, non-breathable clothes after hair removal
• Having high levels of certain hormones that stimulate hair growth

When to see a doctor

See a doctor urgently if:

• The ingrown hair looks infected, with spreading redness, pain, warmth, or fever.
• You see red streaks or feel chills.
• The area gets larger after a few days or a painful lump develops.

Book a routine appointment if:

• The bump does not go away within 1–2 weeks of self-care.
• You get ingrown hairs often and they bother you.
• You have multiple ingrown hairs or large, painful cysts.
• You want advice about prevention or other treatment options.

Diagnosis

A doctor can usually diagnose an ingrown hair just by looking at the skin and asking about your shaving or hair removal habits. In most cases, no special tests are needed.

Tests that may be done

• Usually none – the diagnosis is made from the appearance.
• If the bump looks infected, the doctor may take a swab to check for bacteria.
• If the diagnosis is unclear, the doctor might look at it with a dermatoscope (a magnifying tool) to rule out other skin lumps.

What to expect at your appointment

A doctor will ask where you have the ingrown hair, how long it has been there, and how you remove hair. They may gently touch the skin to feel for tenderness or swelling. They will explain what's happening and give you advice on treatment and prevention — usually this takes just a few minutes.

Treatment

Ingrown hairs often heal without any treatment. Simple home care can help release the hair and calm the skin. If the area becomes infected or keeps recurring, a healthcare provider can offer more options.

Self-care at home

• Stop shaving, waxing, or plucking the affected area for a few days to allow the hair to grow out.
• Apply a warm compress for 10–15 minutes, 2–3 times a day, to soften the skin and help the hair come to the surface.
• Gently wash the area with mild soap and warm water daily to keep it clean.
• Exfoliate with a soft washcloth or a gentle exfoliating scrub to help free the trapped hair.
• If you can see a loop of hair, you can carefully lift it with a sterilized needle or tweezers — do not dig into the skin.
• Avoid squeezing or picking the bump, as this can cause infection and scarring.

Medical treatments

If an ingrown hair becomes infected, a doctor may prescribe a topical antibiotic to apply to the skin. For stubborn or repeated ingrown hairs, they might recommend a prescription cream that helps the skin shed dead cells and reduces inflammation. Other treatments include professional treatments like laser hair removal to reduce hair growth, which can be done by a qualified practitioner. Always ask your doctor or pharmacist for advice about which treatment is right for you.

When is surgery considered?

Surgery is rarely needed. If a painful cyst develops, a doctor can make a tiny cut with a sterile needle or lancet to release the trapped hair and drain any fluid. This is a quick in-office procedure, not a major operation.

Living with this condition

In most cases, an ingrown hair is a minor, short-term skin issue that doesn't stop you from your normal activities. Keep the skin clean and moisturized, avoid tight clothing over the area, and let the hair grow naturally for a while. If it bothers you, treat it gently and be patient — it usually heals within a week or two.

Lifestyle tips

• Use clean, sharp blades when shaving and shave in the direction of hair growth.
• Warm the skin with warm water before shaving, and use shaving cream or gel.
• Avoid shaving the same area repeatedly in one session.
• After shaving, apply a gentle unscented moisturizer.
• Consider trying a different hair removal method, such as electric clippers, if shaving tends to cause ingrown hairs.

Diet and exercise

There is no special diet for ingrown hairs, but eating a balanced diet with plenty of fruits and vegetables supports overall skin health. Exercise is fine, but after working out, shower and dry the skin gently to avoid traps. If you shave areas that rub against exercise clothing, make sure the clothing is clean and not too tight.

Mental health and emotional wellbeing

Ingrown hairs can feel embarrassing, especially if they appear on the face or other visible areas. It may help to remember that they are common and not a sign of being unclean. If they keep happening, they can be frustrating, but talking to a pharmacist or doctor can give you practical solutions. You do not need to feel anxious about a minor bump, and it's okay to reach out for support if it affects how you feel about yourself.

Prevention

Yes, ingrown hairs are usually preventable. The most helpful steps are to shave with clean, sharp blades, use warm water and a shaving lubricant, shave in the direction of hair growth, and exfoliate gently a few times a week. If you get frequent ingrown hairs, consider trying an electric razor or letting hair grow longer before shaving.

Complications

If left untreated

• A minor infection that clears with simple care or antibiotics
• A painful pus-filled cyst called a folliculitis
• Dark spots or temporary changes in skin color, especially in darker skin tones
• Scarring, particularly if you pick or squeeze the area
• Rarely, a larger abscess or skin infection that requires medical treatment

Long-term outlook

The outlook is very good. Most ingrown hairs heal on their own within 1–2 weeks once you stop shaving and treat the area gently. Even stubborn ingrown hairs usually improve with the right self-care or a simple medical treatment. With good prevention habits, you can often stop them from coming back.
