What should you know about Nd:YAG laser treatment for hair removal?

The laser delivers pulses to hair-bearing skin. Energy is absorbed by pigment around the follicle and converted to heat, which can disrupt the follicle’s ability to produce a hair. Only follicles in a suitable growth phase respond at a given visit, so a treatment plan usually involves repeat sessions rather than one appointment.

Nd:YAG light is often selected when a longer wavelength is useful for darker skin tones, but settings still need to be tailored. Hair colour, thickness, body area, tanning, and hormonal factors affect the response. You may notice warmth, a rubber-band-like snap, redness, or small bumps around follicles for a short time.

At consultation, disclose tanning, skin treatments, medicines, cold sores, scarring history, and any change in hair growth. Avoid plucking or waxing before a session if the clinic asks you to preserve the follicle target; shaving may be recommended. Keep the area free from irritants and arrive with clean skin.

After treatment, use cool compresses if advised, avoid friction and heat until the skin calms, and protect exposed areas from sunlight. Do not pick at crusts or bumps. The Nd:YAG platform is described in Nd:YAG Laser, while Laser Hair Removal covers the broader treatment approach.

Call the clinic about intense or increasing pain, blistering, marked swelling, or areas that become dark, pale, or increasingly tender. Urgent assessment is appropriate for spreading redness with fever, pus, facial swelling, or breathing symptoms after a treatment.

Ask whether your hair and skin characteristics are suitable, what to stop before treatment, how many visits may be considered, and which changes require a review.
