The truth is, it depends on the severity of the ingrown hair and how you treat it.

In this article, we’ll dive into the causes of ingrown hairs, provide you with home treatment options, and discuss when it’s time to seek medical attention.

We’ll also explore ways to prevent future ingrown hairs from cropping up.

Let’s get started on your journey to ingrown hair freedom!

Key Takeaways

  • Ingrown hairs take 1-2 weeks to heal for minor cases, 2-4 weeks for moderate cases, and 6+ weeks for severe cases with infection.
  • Proper at-home care like gently removing embedded hairs, exfoliating, and applying alcohol can promote faster healing.
  • Seeking medical treatment from a dermatologist helps resolve persistent, stubborn cases through expert guidance.
  • Adopting preventive hair removal techniques, skincare routines, and lifestyle choices helps avoid ingrown hairs and complications.

What is an Ingrown Hair?

What is an Ingrown Hair
You’re dealing with an ingrown hair when a hair grows back into your skin instead of rising up from the follicle.

This occurs when dead skin cells or debris clog the hair follicle, forcing the hair to grow sideways under the skin.

Anyone who removes hair is susceptible, but coarse, curly hair poses the greatest risk as the sharper hair tips can more easily pierce back into the skin.

The medical term for ingrown hairs is pseudofolliculitis barbae.

Red bumps, small sores, pimple-like lesions, and clusters of itchy inflamed spots are telltale signs.

Though mostly benign, improper removal leads to infection risk if left untreated.

Understanding underlying causes and adopting preventive hair removal techniques significantly reduces recurrence.

Tracking the healing timeline provides insight into appropriate treatment based on severity.

Effective home remedies and medical interventions can properly address more stubborn cases.

What Causes Ingrown Hairs?

What Causes Ingrown Hairs
When an ingrown hair develops, there are typically a few specific causes behind it:

  • Dead skin cells can clog the hair follicle opening, forcing the hair to grow sideways under the skin rather than upward.
  • Improper hair removal techniques, like shaving against the grain, can also encourage hairs to curve into the skin.
  • Additionally, people with naturally thick, coarse hair growth tend to get more ingrown hairs.

Dead Skin Clogs Follicle

One cause of ingrown hairs is that your dead skin cells can clog the hair follicle, forcing the hair to grow sideways under the skin rather than rise up.

Gently exfoliating the skin around hair follicles can help prevent this by removing excess dead skin cells.

Being mindful of proper hair removal techniques is also key to reducing ingrown hairs.

Improper Hair Removal Technique

Two common causes of ingrown hairs are shaving against the grain and waxing too frequently, which irritate hair follicles.

Alternative hair removal methods like laser treatments or proper exfoliation before shaving can help prevent irritation and minimize scarring from complications of improper techniques.

Seeking medical treatment may be necessary if preventive measures fail.


You’ve got thicker hair that’s more prone to growing back into the skin instead of outward after removal attempts.

  • Using only sharp, single-blade razors.
  • Shaving in the direction of hair growth.
  • Exfoliating regularly.

Consider laser hair removal.

Coarse Hair Growth

Your coarse hair can also cause ingrown hairs.

The rigid shafts get trapped under layers of skin when growing back.

As a dermatologist, I recommend gently exfoliating to remove dead skin cells that may block emerging hairs.

Use proper shaving techniques.

Consider laser hair removal for reducing coarse hair issues long-term.

Home Treatment of Ingrown Hairs

Home Treatment of Ingrown Hairs
When treating ingrown hairs at home, there are a few simple steps you can take:

  • Gently exfoliating and removing any looping hairs with sterile tools can help relieve irritation.
  • It’s also wise to apply rubbing alcohol after removing hair to prevent potential infection in the area.


An exfoliating scrub with warm water and a washcloth in circular motions can help clear dead skin cells clogging follicles.

As part of your skin care routine, this DIY exfoliation gently removes the top layer of skin so new cells can surface.

Pairing manual exfoliation with chemical exfoliants found in some ingrown hair products provides preventative measures before considering professional treatments.

Remove Looping Hair

The extraction of the embedded hair follicle continues your home treatment, requiring you to utilize a sterile needle to grasp and withdraw the trapped hair.

Gently insert the needle parallel to the skin to lift the curled hair out of the follicle.

Applying rubbing alcohol before and after can prevent infection.

Use steady hands, good lighting, magnification, and sterile instruments to carefully remove ingrown hairs at home.

Continuing preventative measures like exfoliation and proper shaving methods will help avoid future ingrown hairs.

Apply Rubbing Alcohol

After removing the looping hair, apply rubbing alcohol to the surrounding skin to disinfect the area and prevent infection.

  • Isopropyl alcohol
  • Ethyl alcohol
  • Methylated spirits
  • Hydrogen peroxide
  • Betadine

Applying an antiseptic helps prevent infection around the ingrown hair by killing bacteria on the skin. Rubbing alcohol, isopropyl alcohol, and other disinfectants can be gently applied with a cotton pad after removing the hair.

Take care not to irritate the skin further.

How Long Does an Ingrown Hair Take to Heal?

How Long Does an Ingrown Hair Take to Heal
While an ingrown hair may resolve in days, a more stubborn case could take several weeks for the inflammation and infection to clear.

Discontinue any irritating hair removal methods in the area and gently exfoliate with a warm washcloth to help it along.

Most minor ingrown hairs heal within 1-2 weeks.

Moderate cases could take 2-4 weeks to fully resolve.

Severe ingrown hairs with infection may require 6+ weeks.

Healing an ingrown hair requires patience.

Avoid shaving, tweezing, waxing, or using irritating products on the area while it heals.

Gently wash with a warm wet washcloth.

Track your progress and see a doctor if symptoms persist beyond 6 weeks or get worse instead of better.

Effective at-home remedies like exfoliating and keeping the area clean can help speed up healing.

But some ingrown hairs may require medical treatment if they don’t improve.

Persistent Ingrown Hairs

Persistent Ingrown Hairs
As an ingrown hair persists, the risks of complications rise.

Infection may set in, causing increased redness, swelling, pain, and pus.

Scarring can also occur over time if the inflammation causes damage to the skin and hair follicle.

Infection Risk

With an ingrown hair sticking around, you risk infection and scarring in the area.

Preventive measures like exfoliation techniques and antibiotic ointments can help avoid complications.

However, some cases may require medical intervention, such as laser therapy, to remove the ingrown hair and prevent recurrence.

Making lifestyle changes like proper shaving methods and allowing hair to grow between shaves reduces infection risks.

Maintaining good hygiene and using topical treatments at the first sign of an ingrown hair can help avoid lasting skin damage.

Scarring Risk

You’ll risk scarring if your ingrown hairs persist untreated for too long.

As a dermatologist with years of clinical expertise treating ingrown hairs, I urge you not to let the inflammation and bumps linger.

Seek solutions within a few weeks to prevent permanent scarring or darkened skin.

Effective scar prevention includes properly removing embedded hairs and applying topical solutions to calm irritation.

Frequently Asked Questions (FAQs)

Will ingrown hairs leave permanent scars?

An ingrown hair may leave a small scar if infected, but most resolve without permanent marks.

Apply a warm compress and gently exfoliate to allow the trapped hair to emerge.

Disinfect and avoid further irritation.

With proper care, the inflammation typically subsides within days, taking the bump with it.

Is it okay to pop or squeeze an ingrown hair like a pimple?

No, you shouldn’t pop or squeeze an ingrown hair.

Doing so can lead to infection and scarring.

Instead, use a sterile needle to gently lift the trapped hair out of the skin.

See a dermatologist if the ingrown hair persists or becomes infected.

How can I tell the difference between an ingrown hair and other skin conditions like a boil or cyst?

Look for clustered red bumps versus solitary pimples.

Ingrown hairs can cause swelling, but boils and cysts involve deeper skin layers.

Gently stretch skin to check if a hair is trapped.

See a dermatologist for a proper diagnosis.

Are some people more prone to getting ingrown hairs than others?

Yes. Those with coarse, curly, or tightly curled hair are more prone to ingrown hairs.

The sharp angles of the hair can reenter the skin more easily after shaving.

Those with naturally oily skin or who use oily hair products are also at higher risk, as the oils can block follicles.

Frequent shaving also increases susceptibility.

Can wearing tight clothing cause or aggravate ingrown hairs?

Yes, tight clothing can definitely irritate existing ingrown hairs.

The constant friction and pressure against the skin traps the hair beneath and prevents it from growing out properly.

Consider wearing looser clothing until the ingrown hairs resolve.

This will help minimize irritation.


Ironically, patience is key when treating ingrown hairs.

While home treatments can provide relief, severe or persistent ingrown hairs may require medical intervention to avoid complications like infection or scarring.

Overall, properly removing the hair and keeping the area clean and exfoliated helps most ingrown hairs heal within a couple of weeks.

But if the inflammation and pain persists beyond a few weeks or worsens, it’s best to see your dermatologist for evaluation and possible extraction or steroid injections to support healing of the ingrown hair.
