What should you know about top laser hair removal?

Laser light is absorbed by pigment in the hair and converted into heat around the follicle. Hair commonly grows in cycles, so several appointments are needed to address follicles during a responsive phase. Results vary with hair colour, hair thickness, skin tone, hormones and the body region treated. The aim is usually long-term reduction, although some regrowth can occur and maintenance may be needed.

Alexandrite, diode and Nd:YAG systems use different wavelengths and may suit different combinations of skin tone and hair characteristics. Ask which technology is being used and why it fits you. Laser treatment is different from electrolysis, waxing and shaving, and it does not treat every cause of excess hair.

Arrange a consultation before treatment. Discuss medicines, tanning, pigment changes, keloid scarring, active skin irritation and conditions such as hirsutism or hidradenitis suppurativa. Follow the clinic's advice about shaving and sun exposure; avoid waxing or plucking if instructed because the follicle needs to be present for the laser to target it. Protective eyewear should be used during treatment. Cooling, brief stinging and temporary redness can occur.

If shaving causes bumps, read about Razor Bumps or Ingrown Hairs. A clinician can also explain whether treatment may help hair-related irritation or whether another diagnosis needs attention.

Contact the treating clinic if redness, swelling, blistering, crusting, marked pain or a change in skin colour is worsening or not settling as expected. Seek urgent medical help for facial swelling, widespread hives, breathing difficulty or faintness. Do not treat over an active infection, open wound or severe flare without clinical advice.

Ask which laser wavelength is planned, how your skin tone and hair colour affect the settings, who will perform the procedure, how many visits may be needed, what aftercare is advised, and what alternatives are suitable if the hair is light or hormonally driven.
