Thinking about laser hair removal? Our comprehensive guide covers everything you need to know — from how the treatment works, to how to achieve the best results, and the key differences between laser hair removal and IPL (intense pulsed light) therapy.
What is Laser Hair Removal and How Does It Work?
Laser hair removal is one of the most effective ways to reduce unwanted facial and body hair.
It works through a process called photothermolysis:
-
A precise wavelength of light is released into the hair follicle.
-
The light energy converts to heat, damaging or destroying the bulb.
-
Because the laser light travels in a single, targeted direction, it focuses on the hair follicle without damaging the surrounding skin.
For best results, hair must be treated during the anagen phase (the active growth stage). Hair naturally grows in four phases: anagen, catagen, telogen, and exogen. By targeting follicles in the right phase, regrowth is dramatically slowed or permanently stopped.
Types of Lasers for Hair Removal
Different skin tones and hair types require different wavelengths. The most common medical-grade lasers are:
-
Alexandrite (755nm) – Best for lighter skin tones, highly effective on fine hair.
-
Diode (808nm) – Works well on coarse, dark hair and is suitable for many skin tones.
-
Nd:YAG (1064nm) – Safest for darker skin tones, with reduced risk of pigmentation changes.
IPL (Intense Pulsed Light) is sometimes offered as an alternative, but it uses scattered light at shorter wavelengths. It’s generally less effective and requires more sessions compared to true medical lasers.
Why Choose a Safe, Qualified Provider?
While laser hair removal is widely available, it’s important to remember that lasers are powerful medical devices. If performed incorrectly, there’s a risk of burns, pigmentation issues, or scarring.
At La Rose Clinic, your safety is our priority:
-
We are regulated by the Care Quality Commission (CQC).
-
All practitioners are medically trained and qualified to at least NVQ Level 3 (many hold Level 4, BTEC in Laser, or are registered nurses).
-
Every practitioner completes 4–6 weeks of specialist training, including both theory and practical exams, before treating clients.
-
Our clinical protocols are developed by a team of dermatologists, doctors, and senior nurses to ensure the highest standards of care.
Are There Industry Rules for Laser Hair Removal?
Currently, there is no single national standard for training in laser hair removal in the UK. Some beauticians may only receive a few hours of training before offering treatments.
At La Rose Clinic, we go far beyond the minimum. Our practitioners follow strict medical-grade protocols, ensuring every treatment is safe, consistent, and effective.
How Many Treatments Will I Need?
Laser hair removal works by targeting hairs in the anagen (active growth) phase — but only about 10–20% of hairs are in this stage at one time.
This is why multiple treatments are needed:
-
We usually recommend a course of 8 sessions, spaced 4–6 weeks apart.
-
The exact number may vary depending on the treatment area, hair thickness, and skin type.
-
Some clients may need slightly fewer sessions, while others may benefit from additional top-ups for the best results.
Your practitioner will design a personalised treatment plan after your consultation.
