If laser didn't work at your last clinic — here's why it probably failed

Your appointment was too short to do the job properly

Does the clinic prioritise treatments being carried out thoroughly, professionally and to the very highest standards of safety and efficacy? Many salons and clinics offering laser hair removal prioritise squeezing in as many clients as possible.

If a treatment is rushed, not enough shots are used, areas may be missed, or you may be at higher risk of side effects. We also safely over-deliver on laser energy rather than do the bare minimum. There is a reason why so many of our clients recommend their friends and family to us.

Your hair colour may not have been assessed at all

An initial consultation should include an assessment of your hair to ensure it is suitable for treatment. Many clinics skip this entirely and book everyone — which isn't great, as laser won't be effective for everyone.

Laser works by heating the pigment (melanin) within each hair. There are two types: brownish-black eumelanin and reddish-yellow pheomelanin. Laser heats eumelanin effectively — but has no effect on pheomelanin at all. White hair contains no melanin whatsoever.

For clients with dark ginger hair, we recommend a patch test. If any change in hair growth is noted around 8 weeks after the patch test, a reasonable result may be achievable. If no change occurs, laser is not recommended.

Your hair type wasn't matched to the right treatment

Very fine hair lacks enough pigmentation to reach the temperature required to damage the follicle. The type of hair also matters enormously:

This is why we assess hair type carefully before treatment and only target thicker, darker terminal hair. Once vellus hairs have become terminal, they can then be treated — so it's not the end of the world if you have to wait.

The wrong laser wavelength was used for your skin and hair type

All lasers emit light at a specific wavelength that penetrates to different depths within the skin. Choosing the right one for your hair and skin type is essential for results.

At Mayfair Aesthetics, we use only the authentic, top-of-the-range Soprano system with all three wavelengths — because no single wavelength is optimal for every client.

It might not have been a real laser at all

Unfortunately, there are many counterfeit, knock-off lasers on the UK market being used in clinics every day. Low quality, low power — and simply not safe.

If a clinic is offering extremely low prices, ask yourself: have they invested in the very best authentic equipment, or have they bought a cheap ineffective knock-off? At Mayfair Aesthetics, we use only real, authentic, fully functioning, top-of-the-range Soprano lasers. No fakes, no knock-offs.

The staff weren't properly trained — or trained at all

Laser hair removal should only be carried out by a specialist trained to NVQ Level 4 or higher in laser and light treatments, as well as specific manufacturer training on the device they're using. Without these qualifications, operators are uninsured and in breach of Special Treatments Licence requirements.

We are regularly checked by the special treatments licence departments of our local councils and have been endorsed by Trusted Laser — an independent body overseeing standards across the laser industry.

The lasers weren't properly maintained

Some clinics skimp on servicing to save money. This results in low-power, underperforming lasers — and therefore consistently poor results for clients, even when everything else is done right.

At Mayfair Aesthetics, our lasers are checked and maintained regularly to ensure they operate at the correct power levels. If a breakdown occurs, our repair team can often be on site within a couple of hours — and we keep spare handpieces on hand to avoid any interruption to your treatment course.

Wrong preparation and wrong treatment spacing

Hormonal factors can make treatment more resistant

Hormones play a significant role in how hair responds to laser — and some conditions make treatment inherently more challenging. This doesn't mean laser won't work; it means expectations and maintenance plans need to be realistic.

We successfully treat many clients with PCOS and hormonal conditions. We're simply honest that more sessions are likely needed, and that regular top-up treatments may be a long-term reality for managing hair growth effectively.

A small number of people are naturally more resistant to treatment

Laser works very well for around 95% of people (excluding those with unsuitable hair colour or significant hormonal conditions). For the vast majority, a 60–90% hair reduction is achieved after a full course at Mayfair Aesthetics.

It's important to note that the bikini area, face and sometimes underarms are more resistant than areas like arms, legs, chest and back — so more sessions are typically required in these zones.

In very rare cases, laser may not achieve the expected reduction at all. We would always rather be honest about this upfront than take your money and disappoint you.
