Laser hair removal has rapidly become one of the most sought-after treatments for long-term hair reduction. From smoother skin to freedom from constant shaving or waxing, this advanced treatment promises a more convenient and cost-effective grooming solution. But one common question remains: how long do the results actually last?
If you're considering laser hair removal in London or have recently begun treatment, it's essential to understand what impacts the longevity of your results, how to maintain them, and what to expect from your sessions.
In this guide, we break down everything you need to know about laser hair removal longevity—specifically with a London-based perspective.
Understanding How Laser Hair Removal Works
Laser hair removal works by targeting the melanin (pigment) in the hair follicle with a concentrated beam of light. The light is absorbed by the pigment, which converts into heat and destroys the follicle’s ability to grow hair. It’s a safe and non-invasive procedure suitable for most areas of the body, including the face, legs, underarms, back, and bikini line.
However, the treatment is most effective when hair is in the active growth phase (anagen phase), which is why multiple sessions are necessary to catch each follicle at the right time.
How Long Do Results Last?
Short-Term Results (After Initial Sessions)
After your first few sessions, you may notice a significant reduction in hair growth. Many clients experience up to 20–30% hair reduction after the first session, with more noticeable results following each subsequent treatment. However, it's important to complete the recommended series of 6–8 sessions, typically spaced 4–6 weeks apart, for optimal outcomes.
Long-Term Results (Post Full Treatment)
Once you've completed the full course, most people enjoy long-lasting hair reduction for months, and in many cases, even years. However, laser hair removal is considered semi-permanent rather than 100% permanent. While it significantly reduces hair, some fine, lighter, or dormant hairs may eventually regrow.
In general, you can expect:
80–90% hair reduction in treated areas
Smooth skin with minimal regrowth for 6–12 months post-treatment
Occasional top-up treatments once or twice a year to maintain results
Factors That Influence How Long Results Last
While the treatment offers long-term benefits, several factors can impact how long your results will last:
1. Hair Type and Colour
Laser hair removal works best on dark, coarse hair, as the laser is attracted to pigment. Those with blonde, red, or grey hair may not experience the same level of effectiveness due to lower melanin content.
2. Skin Type
Modern clinics in London use advanced devices like diode and Nd:YAG lasers, which are safe for all skin tones. However, your skin type may slightly affect how many sessions you’ll need or how well the laser targets your hair.
3. Hormones
Hormonal fluctuations—common in puberty, pregnancy, or menopause—can affect hair growth patterns. Conditions like PCOS (Polycystic Ovary Syndrome) can lead to quicker regrowth, even after completing a full course.
4. Body Area Treated
Some areas, like the underarms and bikini line, tend to respond faster than hormonal zones such as the face or chin, where maintenance sessions may be needed more frequently.
5. Quality of the Clinic and Equipment
Choosing a reputable clinic that uses medical-grade lasers and employs qualified professionals can significantly affect the results. High-quality devices provide better outcomes and reduce the chance of skin irritation or ineffective treatment
Maintaining Your Results: Aftercare and Top-Ups
Once you’ve completed your initial sessions, it’s essential to follow a few key maintenance tips:
Schedule Annual Top-Ups
Even with great results, a yearly or biannual maintenance session can help keep your skin hair-free. These quick refreshers ensure that any dormant hair follicles are addressed before they grow back thicker.
Follow Proper Aftercare
Avoid sun exposure for at least two weeks post-treatment
Do not wax or pluck between sessions—shaving is fine
Apply soothing creams like aloe vera and avoid hot baths immediately after treatment
Stay Consistent
Skipping sessions or delaying treatments can reduce the effectiveness of your results. Stick to the schedule advised by your laser technician to stay on track.

It’s a one-time fix.
While you will see a major difference after a few sessions, long-term results require a full course and occasional top-ups.

You can treat any hair type.
Results vary based on hair colour and skin type. A professional consultation helps set the right expectations.
