Key Points: How to prepare for laser hair removal
- Stop waxing, plucking, threading (and epilators) for at least 4 weeks before your first session.
- Shave the area 12-24 hours before your appointment so the laser can target the follicle properly.
- Avoid sun exposure and sunbeds for around 4 weeks, and skip fake tan for at least 2 weeks.
- Arrive with clean, product-free skin (no deodorant, oils, perfume, makeup or heavy moisturiser on the area).
- Pause harsh exfoliation and strong actives (like retinoids and acids) for several days beforehand, if appropriate.
- Tell your therapist about medications, skincare, recent tanning, and any skin sensitivity so settings can be tailored safely.

Starting laser hair removal is exciting, especially if you’ve spent years shaving, waxing, or battling regrowth at the worst possible moment. A little prep makes a big difference to your comfort, your results, and how happy your skin feels afterwards.
At B-Unique, our approach is always the same: keep it safe, keep it personalised, and make sure you know exactly what to do (and what to avoid) before you arrive. If you’re new to it all, this guide will walk you through the essentials.

Why preparation matters
Laser hair removal works by targeting pigment (colour) in the hair and heating the follicle. That means your hair growth cycle, your skin condition, and even things like tanning or certain skincare products can affect the treatment.
The goal is simple: we want the laser to focus on the follicle, not on surface hair or sensitised skin. That’s how you get the best results with the least irritation.
1) Avoid waxing, plucking, threading (and epilators)
Laser needs the hair root (follicle) in place. Waxing, plucking, threading and epilators pull the hair out from the root, which leaves nothing for the laser to target.
What to do: Stop any hair removal that pulls from the root for at least 4 weeks before your first session. If you need to remove hair in the meantime, shaving is the one to stick with.
If you’re not quite ready to commit to a course of laser sessions, or you just prefer a temporary option, take a look at our waxing treatments. (Just remember you’ll want to pause waxing again if you switch to laser.)
2) Shave 12-24 hours before your appointment
This one surprises people: the ideal hair length for laser is basically “invisible”. You want the surface smooth, so the energy goes into the follicle rather than burning hair above the skin.
What to do: Shave the treatment area around 12-24 hours before your appointment. If you shave immediately before, some skins feel a bit reactive. If you leave it too long, visible hair can make the session more uncomfortable.
Avoid: Hair removal creams right before treatment, unless your therapist has advised they’re suitable for you.
3) Stay out of the sun and avoid fake tan
Tanned skin (from the sun, sunbeds or fake tan) can increase the risk of irritation and pigmentation. Because laser targets pigment, extra colour in the skin can interfere with accuracy and comfort.
What to do:
- Avoid sun exposure and sunbeds for around 4 weeks before treatment.
- Avoid fake tan, tinted lotions and gradual tans for at least 2 weeks beforehand.
- If you have to be outdoors, keep the area covered and use a high SPF.
If you’ve recently been away, used self-tan, or your skin is darker than usual, tell your therapist. Sometimes the smartest move is simply waiting until your skin is ready.
4) Arrive with clean, product-free skin
On the day of your appointment, keep the treatment area clean and free from product. Things like deodorant, perfume, oils and heavy moisturisers can create a barrier or react with heat.
What to do: Shower beforehand if you can, then avoid applying products to the area. If you’re treating the face, come without makeup (or arrive a few minutes early to cleanse properly).
5) Go easy on exfoliation and strong actives beforehand
Over-exfoliated or sensitised skin is much more likely to feel uncomfortable during laser, and more likely to react afterwards.
In the week before:
- Skip harsh scrubs on the area.
- If you use strong skincare actives (retinoids, AHAs, BHAs, benzoyl peroxide), consider pausing them for several days beforehand, if appropriate.
If you’re using prescription skincare or acne medication, bring it up during your consultation so we can advise safely and properly.
6) Wear loose, comfy clothing
After treatment, your skin can feel warm or a little sensitive (similar to mild sun warmth). Tight clothing can rub and make things feel worse than they need to.
What to do: Wear loose clothing and soft fabrics, especially for areas like legs, bikini, underarms or back.
7) Be honest in your consultation (it helps us keep you safe)
Laser isn’t one-size-fits-all. Your settings should be based on your skin tone, hair type, sensitivity, and health history.
Tell your therapist about:
- Any medications or supplements (especially anything that might make you photosensitive)
- Skin conditions, allergies, eczema, psoriasis, or recurring irritation
- Recent sun exposure or fake tan
- How your skin reacts to shaving, waxing, or previous hair removal
This is how we tailor the treatment properly and avoid unnecessary reactions.
8) Think course, not one-off
Hair grows in cycles, and laser is most effective when the hair is in its active growth stage. That’s why most people need a course of sessions to get the best reduction.
What to expect: Many clients need multiple sessions, spaced at the right intervals. Consistency matters. It’s the difference between “some improvement” and “why didn’t I do this sooner?”
9) If laser is not suitable, there are alternatives
Laser and IPL are brilliant for many people, but they do not suit every hair type (for example, very light, white or grey hair may not respond well). If that’s you, don’t worry, you still have options.
For stubborn, lighter hairs or small areas, electrolysis hair removal can be a great alternative and is often the next best step when laser is not the right fit.
The bottom line
Your first appointment is the start of a longer-term change, and the prep is what sets you up to get the best out of each session. Keep the follicle intact, keep your skin calm, avoid tanning, shave at the right time, and be upfront in your consultation.

Laser hair removal preparation FAQs
How long before laser hair removal should I stop waxing or plucking?
Ideally, stop waxing, plucking, threading and epilators for at least 4 weeks before your first session. Laser needs the follicle in place to work effectively.
Do I need to shave before laser hair removal?
Yes. Shave the area 12-24 hours before your appointment. This helps the laser target the follicle without burning hair on the surface of the skin.
Can I use fake tan before my appointment?
It’s best to avoid fake tan, tinted lotions and gradual tanning products for at least 2 weeks before treatment. Added pigment can increase the risk of irritation and affect accuracy.
How long should I avoid sun exposure before laser hair removal?
Aim to avoid sun exposure and sunbeds for around 4 weeks beforehand. If you cannot avoid being outdoors, keep the area covered and use a high SPF.
What should I avoid putting on my skin on the day of treatment?
Arrive with clean, product-free skin. Avoid deodorant, perfume, oils, makeup, and heavy moisturiser on the treatment area unless your therapist has told you otherwise.
Can I have laser hair removal if I’m taking medication?
Sometimes yes, sometimes no. Certain medications can increase sensitivity to light or irritation risk. Always tell your therapist what you’re taking so we can advise safely.
What if my hair is very fair, white or grey?
Very light hairs may not respond well to laser or IPL because there’s not enough pigment to target. In those cases, electrolysis hair removal may be more suitable.
