Laser hair removal remains one of the most effective ways to achieve long-term reduction of unwanted hair. At Injectual London, we use the Candela GentleMax Pro Plus — a world-leading dual-wavelength laser system that delivers powerful, precise, and comfortable treatments for all skin types. But how long do the results really last?
This guide explains the longevity of laser hair removal, the factors that influence results, and what to expect from a full course of treatment. We’ll also explore electrolysis — a permanent hair removal option suitable for finer or lighter hairs that lasers may not target effectively.
How Long Do Results Typically Last?
After completing a full course of laser hair removal — typically 6 to 8 sessions spaced 4 to 6 weeks apart — most clients enjoy up to 90% permanent reduction in hair growth in the treated areas.
However, while destroyed follicles will not regrow, your body can develop new follicles over time, particularly in hormonally sensitive zones such as the face, neck, and bikini line.
In general:
-
Results can last 6 to 12 months or longer without maintenance.
-
With annual top-up sessions, many clients maintain long-term hair reduction for years.
Key Factors That Influence Longevity
Several factors determine how long your laser hair removal results will last:
-
Hormonal changes – Pregnancy, menopause, or conditions such as PCOS can stimulate new hair growth.
-
Treatment area – Legs and arms typically retain results longer than areas affected by hormones, like the chin or jawline.
-
Hair and skin type – Clients with dark, coarse hair and lighter skin usually experience the best outcomes.
-
Treatment consistency – Following the recommended schedule ensures hair is treated in the correct growth phase.
Are Maintenance Sessions Necessary?
Yes — maintenance sessions are essential for long-term, sustained reduction. While some clients remain hair-free for extended periods, most benefit from 1 to 2 top-up sessions per year, especially in areas prone to regrowth.
If maintenance is skipped, regrowth may occur — but it is usually:
-
Finer in texture
-
Lighter in colour
-
Slower to grow
Most clients never return to their original level of density, particularly when treated with a medical-grade system like Candela GentleMax Pro Plus.

At Injectual London, we offer both advanced laser hair removal using the Candela GentleMax Pro Plus and precision electrolysis for complete, permanent hair removal — including areas or hair types less responsive to laser treatment.
