We’ve all been there. You’re getting ready, you glance in the mirror or look down at your legs, and there it is—a red, angry, slightly throbbing bump that looks like a pimple but feels way more annoying. It’s an ingrown hair. Your first instinct is probably to grab a pair of tweezers and go to town, but honestly, that's usually how people end up with permanent dark spots or a nasty staph infection.
Stop. Put the tweezers down for a second.
When people search for what to do with ingrown hair, they’re usually looking for a quick "pop" or a magical cream. The reality is a bit more scientific and, frankly, requires more patience than most of us want to hear. An ingrown hair, or pseudofolliculitis barbae if you want to get clinical, happens when a hair strand curls back or grows sideways into the skin instead of rising up through the surface. Your body treats it like a foreign object—think of it as a tiny, organic splinter—and launches an inflammatory response. That’s the redness you see.
The immediate "don't panic" protocol
First, you have to identify what you're dealing with. If the area is hot to the touch, oozing yellow pus, or if the redness is spreading in a weird way, you might have moved past a simple ingrown and into cellulitis territory. See a doctor. But if it’s just a standard bump?
Stop shaving immediately. Seriously. Shaving over an existing ingrown hair is like taking a cheese grater to a wound. You’re just going to slice off the top of the bump, introduce bacteria from your razor, and make the inflammation ten times worse. You need to give the skin a "breathing period" of at least three to four days. During this time, your main job is to soften the skin's top layer, known as the stratum corneum, so the hair can find its way out naturally.

Warm compresses are your best friend. Take a clean washcloth, soak it in warm (not scalding) water, and press it against the bump for ten minutes. Do this three times a day. This isn't just an old wives' tale; the heat increases blood flow to the area and helps soften the keratin plug that’s trapping the hair. Sometimes, the hair will just pop its head out after a few rounds of this. If it does, don't yank it out! Just use a sterile needle to gently lift the loop out of the skin.
Why your hair is acting like this anyway
Why does this happen to some people and not others? Biology is kind of unfair that way. If you have curly or coarse hair, you’re basically a prime candidate for chronic ingrowns. The natural curve of the hair follicle makes it way easier for the tip of the hair to re-enter the skin.
According to the American Academy of Dermatology, people of African descent or those with thick, curly beard hair are significantly more prone to these issues. It’s a structural thing. But it’s also a technique thing. If you’re pulling your skin taut while shaving to get that "baby smooth" finish, you’re actually cutting the hair below the skin line. When the skin snaps back, the hair is trapped underneath. It’s a recipe for disaster.
Chemical exfoliants are the real heroes here. Forget those harsh walnut scrubs that create micro-tears in your skin. You want Salicylic Acid (BHA) or Glycolic Acid (AHA). Salicylic acid is oil-soluble, meaning it can actually get down into the pore and dissolve the "glue" holding the dead skin cells together. If you apply a 2% salicylic acid solution—something like the classic Paulas Choice BHA or even a simple Stridex pad—once a day, you’re chemically clearing the path for the hair.

What to do with ingrown hair when it gets deep
Sometimes the hair is buried so deep you can't even see the "shadow" of it. This is where people get desperate and start "digging."
Don't dig.
If the hair is deep, you need to focus on reducing the swelling. Hydrocortisone cream (1%) can be used sparingly for a day or two to calm the "angry" look. Alternatively, a drop of tea tree oil diluted in a carrier oil can help because of its natural antimicrobial properties. But honestly, sometimes the best thing to do is absolutely nothing. Your body has a way of eventually breaking down the keratin or pushing the hair out through natural skin cell turnover, which happens roughly every 30 days.
Things you should probably throw away:
- Dull razors: If you’ve used it more than five times, it’s a bacteria stick.
- Highly scented aftershaves: The alcohol and fragrance just irritate the raw skin.
- That loofah sitting in your shower: It’s likely a colony for mold and bacteria.
Professional interventions and when to call it
If you’ve tried the compresses and the BHAs and the bump is still there after two weeks, or if you’re getting "clusters" of them, it’s time to see a dermatologist. They might prescribe a topical retinoid like Tretinoin. Retinoids speed up cell turnover so the hair can't stay trapped for long. In more severe cases of pseudofolliculitis barbae, a doctor might even prescribe a topical antibiotic like Clindamycin to kill the bacteria living in the follicle.

Then there’s the permanent solution: Laser Hair Removal.
If you’re someone who gets ten ingrowns every time you shave your bikini line or neck, stop the cycle. Laser hair removal works by targeting the pigment in the follicle and essentially "shutting it down." If there’s no hair growing, there’s no hair to get stuck. It’s an investment, but for people who suffer from chronic scarring (hyperpigmentation) due to ingrowns, it’s life-changing.
The "Perfect Shave" Blueprint
If you aren't ready for lasers, you have to change how you shave. Most of us were taught wrong.
- Hydrate first. Shave at the very end of your shower. The steam and water make the hair much softer and easier to cut.
- Exfoliate gently. Use a washcloth or a gentle chemical exfoliant before you shave to clear away any dead skin that might be blocking the follicles.
- Use a single-blade razor. Those 5-blade "fusion" razors are actually terrible for ingrown-prone skin. The first blade pulls the hair, the second cuts it, and the rest cut it even deeper. A single-blade safety razor or an electric trimmer that doesn't cut quite flush to the skin is much safer.
- Shave WITH the grain. I know, you want it smooth. But shaving against the grain is the #1 cause of ingrowns. Look at the direction your hair grows and follow it.
- Rinse with cold water. This helps calm the skin immediately after the trauma of the blade.
Post-care is not optional
After you shave, or even on days you don't, keep the skin hydrated. Dry skin is brittle skin. When skin is dry, it’s harder for a soft, new hair to poke through. Use a non-comedogenic (pore-clogging) moisturizer. Look for ingredients like ceramides or urea. Urea is particularly cool because it’s a keratolytic, meaning it helps break down excess skin buildup while it hydrates.
What most people get wrong about what to do with ingrown hair is thinking it's a one-time fix. It's actually about managing your skin's environment. If your skin is consistently exfoliated and hydrated, the hairs have a clear highway to the surface. If it’s dry, clogged, and irritated by dull blades, it’s a traffic jam every single time.
Actionable Next Steps
- Audit your tools: Throw out any razor that feels like it’s "tugging" even a little bit. Switch to a single-blade or an electric trimmer if you're prone to bumps.
- The 24-hour rule: If you notice a bump, wait 24 hours before touching it. Apply a warm compress twice in that window.
- Acid test: Incorporate a 2% salicylic acid toner into your routine three times a week on the areas you shave.
- Hands off: Never use your fingernails to squeeze an ingrown. The bacteria under your nails is a fast track to a localized infection that will leave a dark spot for months.
- Check the ingredients: Avoid heavy oils like coconut oil on shave-prone areas, as they are highly comedogenic and can trap hairs before they even start growing.
- Consult a pro: If you see dark spots (post-inflammatory hyperpigmentation) forming, ask a derm about azelaic acid or kojic acid to brighten the area safely.
