Shaving Before Laser and the Patch Test: How to Prepare
Inspired by Rio, perfected in Ealing. A little preparation makes laser more comfortable and more effective. Here is exactly what to do.
Shave the treatment area about 24 hours before your laser appointment, and do not wax, epilate or thread in the weeks before or during your course. The laser needs the hair root in the follicle to work, while hair above the skin can heat the surface. Your consultation and patch test come before your first full session.
Why shave and not wax?
Waxing, epilating and threading pull the hair out from the root, leaving nothing for the laser to target. Shaving removes only the surface hair, so the root stays in place.
When to shave
Around 24 hours before is ideal, so any slight irritation has settled. Use a clean razor and avoid heavily perfumed products afterwards.
What else to avoid
- Sun, sunbeds and fake tan in the weeks before treatment.
- Deodorant, creams or make-up on the area on the day.
- Waxing, epilating, threading or bleaching during your course.
The consultation and patch test
We talk through your goals, medical history, medication and skin, then test a small area. You will be advised when to return for your first session. Read how skin tone and hair colour affect laser.
After your session
Mild redness is normal and usually settles quickly. Follow our laser aftercare guide. Book your consultation at Leon Beauty on Fresha.
Frequently asked questions
Should I shave before laser hair removal?
Yes, about 24 hours before your appointment, unless your therapist advises otherwise.
Can I wax between laser sessions?
No. Waxing removes the root the laser needs. Shave between sessions instead.
What happens at a laser patch test?
A small area is treated to confirm your skin responds well to the chosen settings.
Can I wear deodorant to an underarm laser appointment?
It is best to arrive with clean skin, free of deodorant and creams.
