The short answer
Laser hair removal gives long-term hair reduction, not guaranteed permanent removal; it usually takes six to eight sessions four to eight weeks apart, works best on dark hair, and needs a consultation and patch test first. Costs run from roughly £50–£150 per session for a small area. Suitability depends on your skin tone and hair colour, and a qualified practitioner must assess you. This page answers the most common questions briefly and links to the detailed guides.

Does laser hair removal work, and is it permanent?
Laser hair removal does work for most people with suitable skin and hair, but it delivers long-term hair reduction rather than guaranteed permanent removal of every hair. It works by heating the pigment in the hair follicle to slow or stop regrowth; treated hair often grows back finer and sparser, and many people enjoy long-lasting smoothness with occasional maintenance. It works best on dark hair and poorly on blonde, red, grey or white hair, which contain little pigment. See does it work? and is it permanent? for the full picture.
How many sessions will I need, and how much does it cost?
A typical course is six to eight sessions, spaced four to eight weeks apart, because the laser only affects hair in its active growth phase and repeat sessions catch more follicles over time. Some people need more, and occasional maintenance afterwards is common. Costs vary by area and clinic but run roughly £50–£150 per session for a small area such as the upper lip or underarms, with larger areas or full-body costing more.
Is it safe, and does it hurt?
When carried out by a trained practitioner using the right device for your skin, laser hair removal is generally considered safe, though side effects such as temporary redness, swelling or, less commonly, burns and pigment changes can occur. Most people describe the sensation as a quick snap, like an elastic band, rather than severe pain, and many machines include cooling for comfort. A consultation and patch test reduce the risks. The detail is in is it safe?, does it hurt? and side effects.
| Question | Short answer |
|---|---|
| Is it permanent? | Long-term reduction, not guaranteed permanent removal |
| How many sessions? | Usually 6–8, every 4–8 weeks |
| Does it hurt? | Usually a quick snap; cooling helps |
| Works on light hair? | No — too little pigment to target |
| Safe in pregnancy? | Usually deferred as a precaution |
Who is it suitable for, and what should I check first?
Suitability depends mainly on your skin tone and hair colour. Modern Nd:YAG lasers have made treatment safer for darker skin tones, but light hair of any kind responds poorly. Some situations — pregnancy, certain medications, recent sun exposure or active skin conditions — mean treatment is deferred or reconsidered. That is what the consultation and patch test are for. Before booking, take time over choosing a clinic and read the questions to ask.
How does it compare with other hair-removal methods?
People often weigh laser against waxing, shaving and electrolysis. Laser offers longer-lasting reduction than shaving or waxing for those with suitable skin and hair, because it acts on the follicle rather than just removing hair at or above the surface. Electrolysis, which treats each follicle individually with an electric current, is the only method described as permanent and works regardless of hair colour, but it is slower and less practical over large areas. Laser is faster across bigger areas but limited by hair colour. The right choice depends on your hair, skin, budget and patience.
- Laser vs waxing — longevity versus convenience.
- Laser vs electrolysis — speed versus permanence and colour-independence.
- Laser vs IPL — focused light versus broad-spectrum light.
On cost over the whole course, the total is what matters, not the per-session headline. Small areas such as the upper lip or underarms sit at the lower end, often £50–£150 per session, while legs, back or full-body packages cost considerably more across the course. Many clinics offer course packages that work out cheaper than paying per session, but be cautious about paying large sums up front before a patch test confirms your skin responds well. Our cost guide and is it worth it? pages set out the figures and the trade-offs.
For anything not covered here, follow the linked guides, and when you are ready, start with a consultation rather than committing to a full course. A clinic that assesses you properly, uses the right machine and is honest about results is the foundation of a good outcome.

Frequently asked questions
Is laser hair removal permanent?
It provides long-term hair reduction rather than guaranteed permanent removal of every hair. Treated hair often grows back finer and sparser, and occasional maintenance sessions are common.
How many sessions will I need?
Usually six to eight, spaced four to eight weeks apart, because the laser only affects hair in its active growth phase. Some people need more, and maintenance sessions may follow.
Does laser hair removal work on blonde or grey hair?
Not well. Laser targets the pigment in hair, so blonde, red, grey and white hair respond poorly because they contain little pigment. A consultation can confirm whether it is worth trying for you.
What do I need to do before my first session?
Have a consultation and a patch test with a qualified practitioner, avoid sun exposure, sunbeds and fake tan beforehand, and disclose any medications or skin conditions. These steps protect your skin and set realistic expectations.
