Laser Hair Removal

Laser-based treatment that targets hair follicles to reduce hair growth over a course of sessions.

This is supported by established clinical evidence.

Laser hair removal uses light energy to target melanin (pigment) in hair follicles, damaging the follicle enough to slow or reduce future hair growth. It is one of the most established and widely offered cosmetic laser treatments.

How it works

The laser targets pigment in the hair follicle specifically, which is why hair colour and skin tone both affect how well it works. Darker, coarser hair against lighter skin generally responds most predictably, while very light, fine or grey hair can be harder to treat effectively, since there is less pigment for the laser to target. See Laser Hair Removal treatment information from Laser Clinics Australia for more on the specific protocol used.

Why a course of sessions is needed

Hair grows in cycles, and laser is most effective on hair in an active growth phase. Because not all hairs are in that phase at the same time, a series of sessions spaced several weeks apart is needed to treat hair as it cycles through, rather than a single visit.

Why recent sun exposure matters

Tanned skin contains more surface melanin, which increases the risk of burns and pigmentation changes during treatment, since the laser can be absorbed by the surrounding skin as well as the follicle. In a consistently high-UV climate like Cairns, this is checked at each appointment, not just the first consultation, since a tan can change between sessions. Treatment consultations are available at Laser Clinics Cairns Central.

Potential benefits

+Can meaningfully reduce hair growth over a course of sessions
+Reduces the need for regular shaving or waxing over time
+Suitable for larger areas of the body as well as smaller, more detailed areas

Limitations

·Requires multiple sessions, since hair grows in cycles that respond differently to laser at different stages
·Not equally effective on all hair and skin colour combinations
·Results are hair reduction, not guaranteed permanent removal for every individual

Possible side effects

·Temporary redness or slight swelling around treated follicles
·Rare risk of burns or pigmentation changes, particularly on tanned skin
·Temporary sensitivity in the treated area

What to expect / downtime

Minimal for most people, though some redness in the treated area for a short period afterwards is common.

Suitability

Suitability depends on hair colour, skin tone, and recent sun exposure or tanning. Recently tanned skin generally needs to fade before treatment can proceed safely.
