The short answer
The legs are a large area, so laser sessions take longer and cost more than small areas, but they respond well when hair is dark and coarse. Most people choose full or half legs and complete a course of six to eight sessions spaced four to eight weeks apart, achieving a lasting reduction in hair. Larger surface area means longer appointments; results build gradually and occasional maintenance is normal.
Legs are one of the most popular areas for laser hair removal — a big surface to keep shaving or waxing, and one where a good result makes a real difference to upkeep. Because they are large, the practicalities of cost and time differ from small areas like the upper lip. Here is what treating the legs actually involves.

Full legs or half legs?
Most clinics offer the legs as either full legs (thigh to ankle) or half legs (usually the lower leg, knee to ankle). Some people add the knees separately. Because the legs are one of the largest treatable areas, expect appointments to take noticeably longer than a small area and prices to be correspondingly higher — well above the £50–£150 small-area range. Many clinics offer the legs as part of discounted larger-area or full-body packages, so it is worth comparing using our cost-by-area guide.
The good news is that leg hair is often dark and coarse, which is exactly what the laser targets best — it heats the melanin pigment in the follicle. That tends to make the legs a satisfying area to treat for people whose hair and skin are suited to it, and a popular one for that reason. A patch test will confirm how your skin and hair respond before you commit to a full course, and lets the practitioner settle on safe, effective settings for the larger expanse of skin involved.
How long it takes and how results build
Because of the surface area, a full-leg session can take considerably longer than a small area such as the upper lip or underarms — allow a proper appointment slot. Across a course of typically six to eight sessions, spaced four to eight weeks apart, the hair thins progressively rather than disappearing all at once. The schedule matters because the laser only affects follicles in their active growth phase, so spacing the sessions out catches successive waves of hair as different follicles cycle into growth. Skipping or delaying sessions tends to blunt the result, so it is worth keeping to your clinic’s timetable across the whole course.
| Aspect | What to expect on legs |
|---|---|
| Area size | Large — longer sessions, higher cost |
| Hair type | Often dark and coarse — responds well |
| Course | 6–8 sessions, 4–8 weeks apart |
| Result | Long-term reduction, finer regrowth |
- Shave (do not wax or pluck) before sessions, as advised by your clinic.
- Keep treated legs out of the sun and avoid self-tan — see sun exposure.
- Expect some redness or bumps for a short time after each session.
- Follow aftercare and report any concerning reaction.
Is it worth it for the legs?
For people who currently shave or wax their legs constantly, a successful course can mean far less upkeep over the long term — the key trade-off is the upfront cost against years of reduced maintenance and fewer ingrown hairs. Because the legs are large, the headline price looks high, but spread against how often you currently shave or pay for waxing it can compare favourably over time. Weigh this with our is it worth it page, and set expectations using what results to expect. As with every area, this is long-term reduction rather than guaranteed permanent removal, and occasional maintenance is normal once the main course is complete.
If results stall on the legs, it is usually down to hair colour, settings or spacing rather than the area itself, which generally responds well — our page on why it might not be working covers the common reasons in detail. This page is general information, not medical advice; a qualified practitioner should assess your skin and hair at a consultation and patch test before any course, and individual results vary from person to person.

Frequently asked questions
How much does laser on the legs cost?
More than small areas because of the surface area. Many clinics price full or half legs individually or within larger packages, so compare written quotes and our cost-by-area guide.
How long does a leg session take?
Longer than small areas — full legs are a large surface, so allow a substantial appointment. Your clinic can give a time estimate at consultation.
How many sessions do legs need?
Usually six to eight, spaced four to eight weeks apart, though some people need more. Leg hair is often dark and coarse, which tends to respond well.
Will my leg hair be gone forever?
No treatment guarantees that. Expect long-term reduction with finer, sparser regrowth, plus occasional maintenance sessions to keep results.
