How to Prevent Ingrown Hairs After Laser Hair Removal
Ingrown hairs after laser hair removal are common but preventable. Learn what causes them, the mistakes to avoid, and a simple aftercare routine to keep skin smooth between sessions.
You have just had a laser hair removal session and your skin looks great. Then a week later, small red bumps start appearing. Ingrown hairs after laser hair removal are more common than you think.
Ingrown hairs after laser hair removal are one of the most common concerns our clients raise at Pink Laser Clinics. The good news is they are almost entirely preventable with the right aftercare routine.
In this guide, we will explain why ingrown hairs happen after laser, the three biggest mistakes people make, and a simple daily routine that keeps skin smooth and bump-free between sessions.
Why Do Ingrown Hairs After Laser Hair Removal Happen?
Laser hair removal works by targeting the hair follicle with concentrated light energy. The follicle is damaged, and over the following one to three weeks, the treated hair sheds and falls out naturally. This shedding process is completely normal.
However, during this window, a few things can go wrong. Dead skin cells can build up over the follicle opening, trapping the shedding hair beneath the surface. New hairs growing in between treatment sessions may also curl back into the skin instead of growing outward, especially in areas prone to friction like the bikini line, underarms, and legs.
The result is the classic ingrown hair: a red, sometimes inflamed bump where the hair is stuck beneath the skin surface. It is not caused by the laser itself. It is caused by what happens to the skin afterwards: a blocked follicle.
The 3 Biggest Aftercare Mistakes
Mistake 1: Skipping exfoliation entirely
This is by far the most common mistake. Many people think that because the hair is falling out on its own, they do not need to do anything. But without regular exfoliation, dead skin accumulates and blocks the follicle opening. The shedding hair has nowhere to go, so it curls back under the skin.
Starting gentle exfoliation about seven days after your laser session helps keep the skin surface clear so hairs can shed freely.
Mistake 2: Using harsh physical scrubs
On the flip side, some people go too aggressive. Rough body scrubs, loofahs, and abrasive exfoliating mitts can irritate skin that is already sensitised from laser treatment. This creates micro-tears in the skin, which can actually increase inflammation and make ingrown hairs worse.
What you need is chemical exfoliation, not physical. Salicylic acid gets inside the follicle where the hair is trapped, and gentler acids like lactic acid and urea keep the surface clear, all without any scrubbing or friction.
Mistake 3: Shaving too soon after treatment
Shaving within the first seven days post-laser is a recipe for ingrown hairs. The skin is still recovering, and shaving cuts the hair at an angle just below the surface, making it more likely to grow back inward. Wait at least a full week before shaving the treated area, and always shave in the direction of hair growth when you do.
A Simple Post-Laser Aftercare Routine
Here is the aftercare routine we recommend to our laser hair removal clients at Pink Laser Clinics. It is simple, takes about two minutes a day, and makes a significant difference in preventing ingrown hairs.
Days 1 to 7: Recovery Phase
- Keep the treated area clean and dry.
- Apply a soothing, fragrance-free moisturiser or recovery gel. We recommend Body Soft for lightweight hydration that will not clog pores.
- Avoid hot baths, saunas, swimming pools, and direct sun exposure.
- Do not shave, wax, or pick at the treated area.
- Wear loose, breathable clothing over the treatment area to minimise friction.
Day 7 Onward: Prevention Phase
This is where most ingrown hairs are prevented. Once your skin has settled, introduce a chemical exfoliant into your daily routine.
- Every evening, after cleansing, apply Body Clear to the areas prone to ingrown hairs, such as the bikini line, underarms and legs. Its salicylic acid is oil-soluble, so it gets inside the follicle and clears the dead skin and trapped hair where ingrowns actually start.
- Follow with a hydrating body moisturiser to lock in moisture and support the skin barrier.
- Once the area is settled and staying clear, move to Body Smooth as your everyday finisher to keep skin silky between sessions and beyond.
The routine chain in one line: Body Clear to treat and prevent, Body Smooth as the everyday finisher, Body Soft for hydration. Body Clear was developed at Pink Laser Clinics for exactly this kind of blocked-follicle concern, and Body Smooth, our award-winning multi-acid serum, keeps the result holding with the gentlest daily touch.
What About Ingrown Hairs That Are Not From Laser?
You do not need to be a laser client to benefit from this routine. Ingrown hairs are extremely common after shaving and waxing too. The same principle applies: dead skin traps the regrowing hair, and chemical exfoliation into the follicle prevents the buildup.
If you regularly shave your legs, bikini area, or underarms, a nightly salicylic body serum will significantly reduce the bumps, redness, and irritation that come with regrowth. It also helps with related concerns like keratosis pilaris (those small rough bumps on the backs of arms and thighs), strawberry skin on legs, and general rough or uneven skin texture.
When to See a Professional
Most ingrown hairs resolve on their own with consistent exfoliation and proper aftercare. However, if you notice any of the following, it is worth speaking with your clinician:
- Ingrown hairs that are painful, swollen, or filled with pus (this may indicate infection).
- Dark marks or scarring left behind after ingrown hairs heal.
- Persistent ingrown hairs that do not respond to at-home exfoliation after several weeks.
- Ingrown hairs in areas you have not yet treated with laser but would like to address permanently.
If you are experiencing recurring ingrown hairs from shaving or waxing, laser hair removal may be the long-term solution. By reducing hair growth at the follicle, laser dramatically reduces the likelihood of ingrown hairs occurring in the first place.
Key Takeaways
- Ingrown hairs after laser are caused by dead skin trapping shedding hairs, not by the laser itself.
- Avoid physical scrubs on post-laser skin. Use chemical exfoliation instead: salicylic acid for the follicle, AHAs like lactic acid for the surface.
- Wait at least seven days before shaving a treated area.
- From day seven onward, use Body Clear nightly to keep follicles clear, then maintain with Body Smooth.
- This routine works for ingrown hairs from shaving and waxing too, not just laser.
