If you’ve ever considered laser hair removal, one of the first questions you might ask is: how many sessions of hair removal do I need?
The answer depends on several factors—your skin type, hair colour, the area being treated, and your hair growth cycle. At In-DERM Skin Clinic, we use advanced medical-grade laser technology to deliver personalised hair removal plans that are effective, comfortable, and long-lasting.
In this guide, we’ll walk you through how laser hair removal works, why multiple sessions are needed, and what to expect from your treatment plan.
Why Multiple Sessions Are Necessary
Laser hair removal targets the pigment in the hair follicle during its active growth phase (also known as the anagen phase). However, not all hairs grow at the same time—some may be dormant, while others are just starting to grow.
To effectively disable all hair follicles in a given area, multiple sessions spaced over several weeks are required. This ensures each follicle is treated during its optimal growth window.
Most clients at In-DERM see the best results after 6 to 8 sessions, spaced about 4–6 weeks apart.
Typical Number of Hair Removal Sessions by Area
Different areas of the body respond differently to laser hair removal. Here’s a breakdown of how many sessions of hair removal are typically needed for each area:
| Treatment Area | Average Sessions | Session Duration |
| Upper Lip / Chin | 8+ sessions | 10–15 minutes |
| Underarms | 6–8 sessions | 10–15 minutes |
| Bikini Line / Brazilian | 6–8 sessions | 15–30 minutes |
| Legs (Full) | 6–8 sessions | 30–45 minutes |
| Arms | 6–8 sessions | 20–30 minutes |
| Chest / Back | 6–10 sessions | 30–45 minutes |
What Affects the Number of Sessions?
1. Hair Colour and Thickness
Darker, coarser hair responds more quickly to laser treatments because it contains more melanin (pigment), which attracts the laser’s energy.
2. Skin Tone
Modern laser systems, like the ones at our Chiswick clinic, are safe for most skin types. However, skin tone can affect the laser settings and how quickly results appear.
3. Hormonal Factors
Areas affected by hormones (e.g., chin, jawline, or bikini line) may need more sessions or ongoing maintenance to stay hair-free.
4. Area of Treatment
Larger areas such as the back or legs may require more time per session but don’t necessarily need more sessions than smaller areas.

Your journey begins with a detailed consultation and patch test to assess your skin type, hair density, and treatment goals.
Treatment Plan
Based on your consultation, we’ll create a custom laser hair removal plan, outlining how many sessions are recommended for your skin and hair type.

Visible Results
You may start to notice a reduction in hair growth after just 1–2 sessions, with the most dramatic results appearing after your full course of 6–8 treatments.
Is Laser Hair Removal Permanent?
While laser hair removal offers long-lasting results, it’s not considered 100% permanent. After completing your sessions, you can expect a significant reduction in hair growth—often up to 90% less hair in treated areas.
Some clients may need occasional top-up sessions (once or twice a year), particularly in areas with hormonal sensitivity.

Frequently Asked Questions
1. How many sessions of hair removal do I need for permanent results?
Most clients need 6–8 sessions for long-term hair reduction. Maintenance sessions may be required annually.
2. Why do I need to wait 4–6 weeks between sessions?
Waiting allows hair follicles to move into the active growth phase, making the next session more effective.
3. Can I shave between sessions?
Yes, shaving is safe and recommended. Avoid waxing or plucking, as these remove the hair from the follicle.
4. Is laser hair removal safe for all skin types?
Yes. Our advanced laser technology is calibrated to suit most skin tones safely. A patch test is done before your first treatment.
5. What happens if I miss a session?
Missing a session may delay your results. We recommend sticking to your personalised treatment plan as closely as possible for best outcomes.
