Why is a diode laser used in laser hair removal?

The handpiece delivers repeated pulses to the treatment area. Melanin in the hair shaft and follicle absorbs the light, while the surrounding skin is managed with treatment settings and cooling selected for the individual. The heated follicle may then produce a finer or slower-growing hair over time.

Hair grows in cycles, so one session cannot affect every follicle at the same stage. Results vary with hair colour, thickness, skin tone, body area, hormones, and the settings used. Light or grey hair contains less pigment and may respond differently.

Tell the clinician about recent tanning, medicines that increase light sensitivity, skin conditions, and a history of strong reactions or pigmentation changes. Follow the clinic’s instructions about shaving and sun exposure. Do not pluck or wax treated hairs if the clinician needs the follicle present for the laser to target.

During treatment, you may feel warmth or brief snapping sensations. Protective eyewear is used, and the operator adjusts the device to the area and your skin and hair characteristics.

Mild redness or swelling around follicles can occur after treatment. Contact the clinic if you develop blistering, worsening pain, marked swelling, spreading redness, or a persistent change in skin colour. Keep the area protected from strong sun while it settles and follow the aftercare advice provided.

Ask whether diode laser suits your skin and hair, how the area will be cooled, how many appointments may be needed, and which reactions require review.
