Everything about ingrown hairs: causes, prevention, and treatment
A day or two after shaving. You see it coming: a small red bump, an itchy spot, and if you look closer: a hair that has gone the wrong way.
Ingrown hairs. They are annoying. They keep coming back. And they cause exactly the opposite of what you wanted when you started hair removal.
The bumps. The pain. The marks. It doesn’t have to be this way.
If you understand why ingrown hairs occur, you can tackle and prevent them. This article explains it all.
What is an ingrown hair?
An ingrown hair occurs when a hair, after hair removal, does not grow freely up through the skin but bends back or gets stuck under the skin. Instead of breaking through the skin surface, the hair grows sideways or back into the hair follicle.
Your skin reacts to that hair as if it were an intruder. To your immune system, that is exactly what it is: something that doesn’t belong there. The result is a red bump, sometimes filled with fluid, or a visible hair curling under a thin layer of skin.
It can look like a pimple, but it isn’t one. The difference: with an ingrown hair, a hair is often visible if you look closely, or the area feels firmer and more sensitive.
Why do hairs grow inward?
Ingrown hairs after shaving are caused by a combination of factors. They are almost always linked.
Sharp hair edges from shaving
Shaving cuts a hair at a sharp angle. That point can bend back more easily than a hair that grows out naturally.
With multi-blade razors — the 3 to 5-blade razors from the drugstore — this is extra pronounced. The first blade lifts the hair, after which the following blades cut it. The result: the hair edge is literally cut below the skin surface. The hair must first grow further before it reaches the skin again, and in that time, it can go the wrong way.
A single blade cuts the hair straight in one movement, at the skin surface. Not deeper. That is exactly the difference.
Dead skin cells clogging the way
If your skin is not regularly exfoliated, dead skin cells build up around the hair follicles. The hair cannot get through and therefore grows sideways or backward. This is one of the most common causes.
Tight clothing and friction
Immediately after hair removal, your skin is sensitive. Tight elastic or synthetic fabric pushes loose hairs back into the follicle. This causes a hair to grow inward that would otherwise have just come out.
Dry, tight skin
Dry skin is less elastic. Hairs trying to break through find less room. Hydrating after shaving isn’t just for the feeling: it literally makes the skin more supple and accessible for growing hairs.
Curly or coily hair structure
If your hair is naturally curly, the chance of ingrown hairs is higher. The hair curls back along the shortest path, and that path sometimes leads into the skin.
Which areas are most sensitive?
The bikini line is the hotspot. Thin skin, lots of friction, tight underwear: ideal conditions for ingrown hairs. But armpits, legs, and the pubic area are also places where they regularly appear.
The more sensitive the skin, the higher the chance. And the less attention you pay to preparation and aftercare, the more persistent the problem.
What you absolutely should not do
This is where it goes wrong for many people.
It is tempting to pick. With a needle, your nails, tweezers. You see the hair, you want it out, and so you start digging. Understandable. But not smart.
Picking increases the inflammation and the chance of marks. A small superficial irritation thus becomes a deep wound that needs weeks to heal. There is a way to safely remove an ingrown hair, but it requires preparation and the right approach.
What you also shouldn’t do: shave over an active inflammation. Your skin is already irritated. Shaving makes it worse and spreads bacteria.
How to prevent ingrown hairs
Prevention is always easier than cure. These are the steps that make the difference.
Exfoliate regularly
Exfoliating 1-3 times a week removes dead skin cells and keeps the hair follicles clear. Don’t do it on the day of the shave itself: your skin is too sensitive then. Use an exfoliant that is safe for sensitive zones like the bikini line.
The Kjarr scrub & peel from YIONN is specially developed for skin after hair removal. It removes clogging around the hair follicle without damaging the skin, and you can tell.
Keep your skin supple after shaving
Dry skin keeps hairs trapped: if the skin is not supple, hairs find less room to break through. Hydrating after shaving is therefore not just for the feeling, but also ensures that the hair follicles remain open and accessible. A good aftercare does exactly that.
The Náinn aftershave balm is not a greasy hydrating cream, but a light aftercare that soothes the skin barrier immediately after shaving. It protects against irritation and keeps the hair follicles supple. Exactly what you need at that moment.
Maintain your skin daily
The Raka treatment lotion from YIONN maintains the skin daily, even on days you don’t shave. With salicylic acid, it works inside the hair follicle: it dissolves keratin build-up before it blocks the exit. This way, you keep hair follicles structurally clear and prevent ingrown hairs from returning.
Choose the right razor
A single blade razor cuts cleaner and leaves the hair at the right level. Above, you can already see why that matters for ingrown hairs.
Shave with the grain
Shaving against the grain gives a smoother result at the moment, but increases the chance of ingrown hairs afterward. Shaving with the grain is gentler on your follicles.
Wear breathable clothing after hair removal
Give your skin space. Tight elastic immediately after shaving pushes hairs back into the follicle. Cotton or loose clothing keeps the pressure away when your skin is most sensitive.
What to do if you already have them?
Ingrown hairs that are already present require a different approach than prevention. Take it easy.
First, give the inflammation a chance to calm down. Use a warm, moist cloth to soften the skin: this helps move the hair closer to the surface.
The Raka lotion from YIONN supports this process: daily use soothes the skin, reduces inflammation, and helps repair the skin. Even if there are already active ingrown hairs.
The best advice: leave it alone and give the skin time to resolve it itself. Can’t you really resist? Then read here first how to handle it safely without further damaging the skin.
Can ingrown hairs leave marks?
Yes, especially if you pick or keep shaving over an active inflammation. A deep or chronic inflammation can leave hyperpigmentation (a dark spot) or a small mark, even long after the hair is gone.
The best way to prevent marks: treat ingrown hairs early and gently. The less resistance you offer to the inflammation, the less chance of permanent damage.
5 persistent myths about ingrown hairs
From ‘if you shave harder they go away’ to ‘wet exfoliating is always good’: there are plenty of myths around. Which ones are true and which aren’t? Read it here.
And also know that not every red bump after shaving is an ingrown hair. Sometimes it’s shaving irritation, a sweat bump, or a reaction to the shaving cream.
You’ll get there with the right approach
Ingrown hairs are annoying, but they are also understandable. Your skin reacts to something it sees as a disturbance. With the right routine, you give it the space and support so it doesn’t have to.
A good exfoliant. Gentle aftercare. And some patience. That’s really all it takes.

Frequently Asked Questions
How long does it take for an ingrown hair to go away on its own?
In most cases, an ingrown hair resolves itself within one to three weeks, as soon as the hair is long enough to break through the skin. Regular exfoliation speeds up this process by removing the layer of dead skin cells above the hair follicle.
How do you distinguish an ingrown hair from a pimple?
With an ingrown hair, you often see a hair visibly curling under a thin layer of skin, or the area feels firmer and more sensitive than a regular pimple. A pimple has no hair and is caused by a clogged sebaceous gland, not by a bent-back hair tip.
Why do ingrown hairs keep coming back?
Ingrown hairs return because the causes — dead skin cells, sharp hair edges, and a disrupted skin barrier after shaving — are present again with every shave. Without a structural routine (exfoliating, soothing, daily care), the skin repeatedly builds up the conditions in which hairs grow inward.
Can you remove an ingrown hair yourself?
Yes, but only if the hair is visible just under the skin and the inflammation has already subsided. Soften the skin first with a warm cloth, use a sterilized needle to gently free the hair, and never pick at an active, red, or swollen spot — that increases the chance of marks.
Which hair removal method gives the fewest ingrown hairs?
Shaving with a single blade razor gives the fewest ingrown hairs. A single blade cuts the hair straight at the skin surface. Multi-blade razors first pull the hair up and then cut it below the skin, causing the hair to snap back and grow inward. Waxing and epilating actually increase the chance of ingrown hairs because the hair is pulled completely from the root and the new hair grows back without a sharp point.

YIONN Raka is truly a top product! A gentle solution for those annoying, painful ingrown hairs, especially when combined with the scrub.

I thought: you know what, I’ll just give it a try! OMG!!! I really should have done that sooner. I’m 37 now and for the first time, I dare to wear a bikini bottom with pride
. What a miracle cure! Not a single bit of irritation to be found. It’s still bizarre. And I really suffered from it.
Nikkie zijlstra
A product that does what it promises, easy to use. I now have almost all the products and won’t use anything else.
Alice
After 2 weeks, I already noticed a difference. Almost no bumps and itching anymore after shaving. I’m definitely going to try more products.
Patricia Tikar
I’ve often used things like this but they never helped me, even though others were always satisfied with them, and I felt the same about
this product too, but I ordered it anyway and it took a bit longer for me, but it definitely helped!
Maria Ilgun
Much less irritation and bumps. The shaving gel and Raka are truly my favorites; last time I bought shaving foam out of necessity and immediately got bumps
and irritation again…

Free from your shaving irritation within 3 weeks: or your money back
That is my promise to you!
From certified nurse to hair removal expert:
I’m Wendy, the founder of YIONN. I know better than anyone what it’s like to go through life with shaving discomforts.
After desperately trying all sorts of ways and remedies for red shaving bumps and ingrown hairs and spending a lot of money, I was
sick of it.
I decided to find a solution for my shaving irritation myself that actually worked, and I succeeded!
I developed Raka, a caring lotion based on rose water, camphor, and willow bark. By applying a thin layer to the problem area, it easily and quickly calms the skin after hair removal, prevents red bumps, and lets the hair grow out again—instead of in.
And with that, I could finally say goodbye to my insecurity and discomfort.
Hallelujah.
When it later turned out that Raka worked not only for me but also for many other women, I started creating several other products around it that can make hair removal a pleasant experience again.
And because I am so convinced of how it works and I don’t want to keep your money in the rare case that you aren’t satisfied, I came up with the unique YIONN 30-day money-back guarantee (a guarantee you normally never get on hygiene products).
