Types of Laser Hair Removal

Alexandrite lasers use a shorter wavelength and are often selected for lighter skin and dark hair after assessment. Diode lasers use a different wavelength and can be adjusted for a wider range of skin tones. Nd:YAG lasers use a longer wavelength that penetrates more deeply and is commonly considered when the skin contains more pigment. None of these labels alone determines suitability: hair colour, thickness, treatment site, tanning, medicines and cooling also matter. Laser energy works best when hair pigment absorbs the light; very light, grey or red hair may respond less predictably.

A qualified practitioner should examine the area, ask about tanning and medicines, and perform a cautious test when appropriate. Avoid plucking or waxing before a session because the follicle needs to be present; follow the clinic’s shaving instructions instead. Protect treated skin from strong sun and tell the practitioner about recent tanning, active irritation, scars or a history of pigment changes. Laser treatment may also be discussed for unwanted hair linked with hirsutism, or for recurrent razor bumps and ingrown hairs, but the underlying condition may need separate care.

Contact the clinic if redness, swelling, blistering, crusting or pain is worsening rather than settling. Seek prompt medical advice for spreading redness, pus, fever or severe swelling. Delay treatment and request an assessment if the area has an active rash, infection or recent significant sun exposure. Sudden excess hair growth, especially with other hormonal changes, warrants medical evaluation rather than cosmetic treatment alone.

Ask which wavelength and settings suit your skin and hair, who will perform the treatment, how cooling is used, and what changes in pigment or hair growth are possible. Ask whether a medical cause of excess hair should be checked and how you should prepare between sessions.
