"Won't my hair grow back thicker?" "Isn't laser only for pale skin?" "My friend said one session was enough." I hear these every week. There's a lot of confusing information about laser hair removal online, so here are the most common myths, and the honest truth behind each one.
Most of what you've heard is half true
Laser hair removal gives a long-lasting reduction in hair, not instant or guaranteed permanent removal. It takes a course of sessions, works on all skin tones with the right laser, and needs dark hair to target. Your free consultation and patch test is where we find out what's realistic for you.

Myth 1: "Laser makes hair grow back thicker"
Shaving and laser both make hair coarser
This idea usually comes from shaving, where the blunt tip of the regrowing hair can feel stubbly.
Regrowth is usually finer and sparser
Laser targets the hair follicle, so treated hairs tend to grow back finer, lighter and slower, and many don't grow back at all.
In very rare cases, fine hairs near a treated area can be stimulated rather than reduced, usually on the face or neck. It's uncommon, and it's one of the reasons I assess your hair type carefully and choose the right settings for you.
Myth 2: "Laser only works on pale skin"
Darker skin can't be treated safely
Older lasers and many IPL machines struggled to tell the difference between skin and hair pigment.
The right laser treats all skin tones
A long-pulse Nd:YAG laser bypasses most of the pigment in the skin's surface, so it can be used on light, olive, brown and Black skin.
Every client has a patch test first, so we can see how your skin responds. You can read more in my guide to laser hair removal for dark skin and how a solid-state Nd:YAG laser works.
Myth 3: "One session is enough"
One appointment clears the area
You will notice a difference after your first session, but it's only the start.
It takes a course of sessions
Hair grows in cycles, and laser only treats hairs in their active growth stage. Most people need 6 to 10 sessions, spaced 4 to 8 weeks apart.
Hormones, the area treated and your hair type all affect how many sessions you'll need. Here's what to expect after your first session.
Myth 4: "Laser removes hair permanently, forever"
You'll never see a single hair again
Some adverts promise permanent removal, which sets unrealistic expectations.
A long-term reduction
Most clients see a significant, long-lasting reduction. Hormonal changes can trigger new growth over time, so occasional top-up sessions are normal.
I explain this in more detail in Is laser hair removal permanent?
Myth 5: "Laser hair removal is really painful"
It's worse than waxing
Pain is personal, but most clients are pleasantly surprised.
A quick snap or warm flick
Most people describe it as a rubber band snapping on the skin. Built-in cooling helps, and each pulse lasts a fraction of a second.
Sensitive areas like the bikini line and upper lip can feel stronger, and it usually gets easier as the hair thins. Read my honest guide to whether laser hurts.
Myth 6: "Laser works on any hair colour"
Grey or blonde hair can be lasered too
It's a common assumption, and it's where some clients end up disappointed.
Laser needs pigment to work
The laser targets the melanin in your hair. Grey, white, very light blonde and some red hair don't have enough pigment to respond.
I'll always tell you honestly at your consultation if your hair colour isn't suitable, rather than selling you a course that won't work.
Myth 7: "You can't have laser in summer"
Laser is a winter-only treatment
Autumn and winter are popular, because skin is less exposed to the sun.
You can, with care
You can be treated all year round, as long as you avoid tanning and sunbeds, and protect the area with SPF 50 for two weeks before and after each session.

Myth 8: "You can wax or pluck between sessions"
Any hair removal is fine
It's tempting to keep waxing between appointments, especially before a holiday.
Shave only
Waxing, plucking and epilating pull the hair out from the root, which leaves nothing for the laser to target. Shaving is safe, and is what you should do before each session.
Find everything you need to do before and after each appointment in my pre and post care guide.
Results vary from person to person. Your skin, hair colour, hormones and the area treated all play a part, which is why every treatment starts with a free consultation and patch test.
Frequently asked questions
Does laser hair removal make hair grow back thicker?
No. Treated hairs usually grow back finer, lighter and sparser, and many don't grow back at all. In very rare cases, fine hairs near a treated area can be stimulated, usually on the face or neck.
Can laser hair removal be done on dark skin?
Yes. A long-pulse Nd:YAG laser is suitable for all skin tones, including brown and Black skin. A patch test is always carried out first.
How many laser sessions will I need?
Most people need a course of 6 to 10 sessions, spaced 4 to 8 weeks apart, because laser only treats hairs in their active growth stage.
Does laser work on grey or blonde hair?
Laser needs pigment in the hair to work, so grey, white and very light blonde hair don't respond well. This will be checked at your consultation.
Can I wax between laser sessions?
No. Waxing, plucking and epilating remove the hair root that the laser needs to target. Shaving is the only hair removal you should use between sessions.
