You’re getting laser hair removal – here’s what you need to know

Published on 24 April 2024 - Last updated on 19 December 2025 by Beth Ryan

You’ve bitten the bullet, and gone for laser hair removal. (Those rumours you’ve heard about it banishing all your unwanted hair for years were too much to ignore.) But if that first appointment’s edging closer and you’re now starting to wonder what you’ve signed up for, here’s what to expect.

  • 1 Pre-appointment: shave and stay in the shade

    Sure – it's not quite a party, but shaving and staying out of the sun is one of the best ways you can prepare. The laser hair targets pigment, not hair, so it's fine if you want to shave. (The laser also burns any surface hair it meets on the way.) If you've got a tan, even if it's out of the bottle, it can confuse things. So swap your St. Tropez glow for factor 50 in the run-up to your appointment. Life's all about compromise, after all.

  • 2 At least 24 hours before: expect a patch test

    If you're anything like us, the word 'test' recalls espresso-fuelled revising sessions and sweating our way through exams. Happily, this test is just a quick check-up on a small area – it usually takes a couple of minutes – to make sure laser's for you.

    Your therapist will use settings tailored to your skin and hair type, starting at a lower level and gradually increasing till they achieve a good 'clinical endpoint' (that means it's a realistic test). With a touch of aloe vera, the skin usually recovers quickly.

  • 3 During: they'll protect your eyes and skin

    These lasers aren’t like the ones from Star Wars but the bright light can still hurt your eyes. You'll be given some special sunglasses, so you'll look like a rock star. Kind of. As for your skin, the therapist will give the treatment area a good smear of cold gel before the laser fires up. This keeps your skin feeling serene while the warm beam does its business.

  • 4 ...And as for the pain factor, it's not so bad

    We saved the best bit till last. It ranks low on the pain scale. Well, it feels a bit like someone bouncing a bristly hairbrush on it your skin – odd, sure; bearable – definitely. Even better, it'll all be over in about 20 minutes. Remember, it'll take between six to eight sessions for all the hair to be zapped, so don't be disappointed if it's not all gone after session one.

FAQs

How should you prepare for your laser hair removal appointment?

Shave the area and avoid the sun before your appointment. The laser targets pigment, so shaving is fine, but any tan—including fake tan—can interfere with the results. Swap darkening lotions for factor 50 and keep the skin as close to its natural shade as possible.

Do you need a patch test before laser hair removal?

Yes, you need a patch test at least 24 hours before your first session. This quick two-minute check ensures the laser is suitable for your skin and hair type. The therapist adjusts the settings and applies aloe vera for a fast recovery.

What can you expect during a laser hair removal session?

Your therapist will protect your eyes with special sunglasses and apply a cold gel to your skin. The laser feels warm, but the gel helps keep the area comfortable while the treatment is completed.

How painful is laser hair removal?

The discomfort is minimal and ranks low on the pain scale. It feels like someone bouncing a bristly hairbrush against your skin, which most people find bearable. Each session lasts about 20 minutes.

How many laser hair removal sessions do you need to remove all hair?

Most people need between six to eight sessions to fully remove unwanted hair. Don’t expect all hair to be gone after the first session, as results build over time with each treatment.

Can you book laser hair removal appointments online?

Yes, you can book beauty appointments online at favourite salons through Treatwell. The process is simple, hassle-free, and you can arrange everything on the go.
