Underarm epilation has a devoted following. Pull the hair from the root and you can go weeks without a touch-up — no stubble by Tuesday, no reshaving before a weekend trip. The trade-off is real: your underarms are one of the most sensitive spots on your body, thin-skinned, constantly moving, and tucked into a warm fold that traps friction. Done carelessly, epilation here causes pain, irritation, and stubborn ingrown hairs. Done well, it can be a genuinely low-maintenance routine.
This guide walks you through exactly how to do it well — and flags honestly where a sharp safety razor is the more skin-kind choice.
What You Actually Need Before You Start
Hair length. Your epilator needs something to grip. Aim for 2–3 mm (roughly a week to ten days of regrowth after shaving). Too short and the tweezers skip past; too long and the tug is sharper.
A quality epilator. Look for one with at least 40 tweezer discs and a wet/dry rating so you can use it in the shower, where warm water genuinely softens the process. Braun, Panasonic, and Philips Lumea are the names that dominate dermatologist round-ups.
Exfoliant. A gentle physical or chemical exfoliant (lactic acid works well for underarms) used the day before removes dead skin that traps regrowing hairs. This is the single biggest prevention step for ingrown hairs, which the American Academy of Dermatology links directly to blocked follicles.
Alcohol-free soothing gel. Aloe vera or a fragrance-free calming moisturiser for after. Deodorant goes on only once redness has fully settled — at least 24 hours later.
Step-by-Step: How to Epilate Underarms
Step 1 — Shower first
A 10-minute warm shower opens hair follicles and removes deodorant residue. If your epilator is wet/dry-rated, epilating in the shower is genuinely less painful because warm water keeps skin pliable. Pat dry if using a corded model.
Step 2 — Raise your arm and pull skin taut
Reach your arm overhead and rest your hand on the back of your head. This stretches the armpit skin and reduces the folding that causes the epilator to catch awkwardly. Taut skin is faster, more thorough, and less uncomfortable.
Step 3 — Start on the lowest speed
Most epilators have two settings. Begin on slow — it is less aggressive on sensitive skin and lets you find the right angle before committing to a full pass. Beginners especially: resist the urge to rush.
Step 4 — Hold the device at 90 degrees, move slowly against hair growth
Unlike leg epilation, underarm hair grows in multiple directions. Run the epilator in short, steady strokes in one direction first, then cross-hatch in a second direction to catch hairs that faced the wrong way on the first pass. Hold the device perpendicular to your skin, not at a shallow angle, and let the tweezer wheel do the work — do not press down.
Step 5 — Soothe immediately
Rinse with cool water to close follicles, then apply aloe vera gel or a fragrance-free calming moisturiser. Expect mild redness and small raised bumps (follicular reaction) for up to 24 hours — this is normal. Skip deodorant, tight clothing, and the gym until redness clears.
Step 6 — Exfoliate twice a week between sessions
This is where people go wrong. Post-epilation care is as important as the epilation itself. A gentle exfoliation twice a week prevents dead skin from trapping regrowing hairs and keeps that dreaded sandpaper texture at bay.
Managing Pain: Honest Expectations
Underarm epilation hurts more the first few times. The skin adapts — most regular epilators report discomfort drops significantly after three or four sessions as hair comes in finer and follicles become accustomed. A few strategies that genuinely help:
- Warm shower beforehand — the most consistently cited reducer of discomfort across user communities and brand guides alike
- Timing around your cycle — pain sensitivity increases in the days before your period; epilate in the week after for a noticeably easier experience
- Numbing? Skip it — topical numbing creams are overkill for underarms and can mask irritation signals you actually want to notice
When the Epilator Is Not the Right Tool
Epilation is not a universal upgrade over shaving. There are specific situations where a quality safety razor is the cleaner, kinder choice:
Active skin irritation or a razor bump flare-up. Pulling hairs from inflamed follicles worsens irritation and risks infection. Switch to a gentle shave until the skin is calm.
Post-waxing or post-laser skin. Give sensitised skin at least two weeks to fully recover before introducing an epilator.
In a hurry. Epilation done rushed is epilation done badly — missed hairs, skin caught in the wheel, unnecessary soreness. A smooth pass with a Freya starter kit takes two minutes and leaves you genuinely smooth without the commitment of a full epilation session.
Fine, sparse regrowth between epilations. Many women find a quick, light shave on day 10 or 11 is faster and gentler than firing up the epilator for a handful of hairs. A safety razor with a single, fresh blade is precise enough to do this without disrupting the longer root-pull cycle. See how we approach the full body in our shaving by body area guide.
The two methods are not rivals — they complement each other. Epilate for the long smooth stretches; reach for a quality razor for quick maintenance, last-minute smoothing, or whenever your skin needs a break.
Ingrown Hairs After Epilation: Why They Happen and How to Stop Them
Ingrown hairs form when the regrowing hair tip is blocked by dead skin and curls back into the follicle. The AAD identifies this as the key mechanism: the follicle gets clogged, the hair has nowhere to go, and it grows sideways into the dermis. Epilation does not cause more ingrown hairs than shaving per se, but it does pull the hair from a deeper point — so if your exfoliation routine is poor, the regrowth has further to travel and more chance of getting trapped.
Prevention in three steps:
- Exfoliate 24 hours before each session (never immediately before — you want calm skin going in)
- Exfoliate gently twice a week between sessions
- Moisturise daily — dry skin = slower cell turnover = more blockage
If you do get an ingrown, do not pick. A warm compress twice daily helps the hair surface naturally. Persistent or infected ingrowns should be assessed by a healthcare professional.
Quick-Reference Summary
| Stage | What to do |
|---|---|
| Day before | Gentle exfoliation |
| Day of | Warm shower, pat dry, epilate slowly on taut skin |
| Immediately after | Cool rinse, aloe vera gel |
| 24 hrs later | Deodorant back on, back to normal |
| Ongoing | Exfoliate 2x/week, moisturise daily |
| Next session | Every 3–4 weeks once established |
Underarm epilation rewards patience and preparation. Get those two things right, pair it with a good razor for the in-between days, and you will have the smoothest, lowest-drama underarm routine you have had.
Frequently Asked Questions
How long does hair need to be before epilating underarms?
Around 2–3 mm — about a week to ten days of regrowth after shaving. That is enough length for the tweezer discs to grip cleanly without the extra pain that comes from longer hair caught in the mechanism.
Does epilating underarms hurt a lot?
It is more uncomfortable than shaving, especially the first few times. The two biggest pain-reducers are epilating in a warm shower (which softens the skin and loosens follicles) and timing your session for the week after your period, when pain sensitivity is lower. Discomfort decreases noticeably after three or four regular sessions.
How often should you epilate underarms?
Every three to four weeks once you are established. In the first couple of months, hairs will not all be on the same growth cycle, so you may need to go over the area every two weeks until the regrowth synchronises.
Can epilating underarms cause ingrown hairs?
It can, but consistent exfoliation almost eliminates the risk. Ingrown hairs form when dead skin blocks the follicle opening and the regrowing hair curls back under. Exfoliating gently the day before each session and twice a week in between keeps follicles clear.
Is it better to shave or epilate underarms?
It depends on your skin and your schedule. Epilation gives longer smoothness (two to four weeks) but needs preparation and some tolerance for discomfort. A quality safety razor is faster, gentler on sensitive or irritated skin, and ideal for quick touch-ups between epilating sessions — most women use both depending on the day.
