Aesthetic comparison
Laser, waxing or electrolysis: which one is actually right for you?
Three methods, three technologies, three budgets. This clinical guide from Réhabital compares SharpLight laser, hot waxing and electrolysis by real-world efficacy, 3-year cost, pain and skin type.
Quick answer
Short answer: SharpLight laser is the best result-per-hour option for most people with dark hair and light-to-medium skin (6–8 sessions for ~80% permanent reduction). Waxing is still useful for occasional touch-ups or very light hair. Electrolysis is the only truly permanent method for white, grey or blond hair, but it is slow and expensive on larger areas.

The clinical perspective
The SharpLight laser technology used at Réhabital targets the melanin in the hair: light is absorbed by the dark pigment then converted to heat that destroys the follicle without damaging surrounding skin. That is why the best candidates have a clear contrast between skin and hair. Our platform is validated up to Fitzpatrick V, making it safe for Mediterranean, Middle Eastern, Latin and South Asian skin.
Waxing works mechanically: it pulls the hair from the root, which then grows back in 3–5 weeks. The result is immediate but transient. It is a great choice for a one-off event, for people with very light hair (which laser cannot target), or during pregnancy when laser is avoided as a precaution.
Electrolysis inserts a fine needle into each follicle to electrically neutralise it. It is the only technique recognised by Health Canada as strict "permanent hair removal" and the only one that works on white, grey or blond hair. The drawback: treating a full leg would take dozens of hours, making it suitable only for small targeted areas (chin, lip, isolated hormonal hairs).
Our clinical recommendation at Réhabital is often hybrid: SharpLight laser for large dark-hair areas (legs, back, bikini, underarms) and electrolysis to finish the few remaining light hairs. This combination gives the best 3-year value while reaching the most definitive result possible.
