What should you know about electric laser hair removal?

A laser delivers light into the hair shaft and follicle. The follicle absorbs that energy as heat, which can interrupt its ability to produce a hair. Hair grows in cycles, so only follicles in a suitable growth phase respond at each appointment. Several visits are commonly planned, and maintenance may be discussed because hormonal changes and new growth can affect results.

Dark, coarse hair usually gives the device more pigment to target than very light hair. Different systems suit different skin and hair combinations. Alexandrite, diode, and Nd:YAG lasers have different wavelengths and safety considerations; a trained clinician should choose the technology and settings after examining your skin, hair, and treatment area.

Tell the clinic about recent tanning, medicines, a history of abnormal scarring, active skin disease, and previous reactions to light-based treatment. Avoid plucking or waxing before treatment because the follicle needs to be present for the laser to target it. Follow the clinic's instructions about shaving, sun exposure, and skin products.

During treatment, you may feel warmth or snapping. Temporary redness or swelling around follicles can occur. Keep the area protected from strong sun, avoid irritating products until the skin settles, and contact the provider if the reaction is worsening rather than calming.

Seek prompt medical advice for blistering, marked pain, spreading redness, pus, fever, or a change in skin colour that does not settle. An assessment is also sensible when unwanted hair appears suddenly, is accompanied by irregular periods or other hormonal symptoms, or when repeated treatment produces no meaningful change.

Ask which laser matches your skin tone and hair colour, who will perform the treatment, how the area should be prepared, what reactions are expected, and what aftercare is needed.
