Different types of laser hair removal

Alexandrite lasers use a shorter wavelength and are often considered for lighter skin with darker hair. Diode lasers work at an intermediate wavelength and may be selected for a broader range of skin tones. Nd:YAG lasers use a longer wavelength that can be useful when treating darker skin, because it reaches the follicle with less absorption in the surface pigment. These are general principles, not a personal prescription.

Laser energy is absorbed mainly by pigment in the hair shaft and converted to heat around the follicle. Hair colour, thickness, growth phase, recent tanning, medicines and the body area all affect the plan. Laser treatment reduces hair growth; it does not remove every hair forever.

At a consultation, disclose tanning, skin conditions, medicines and any history of unusual scarring or pigment changes. Ask which wavelength is proposed, why it suits your skin tone and hair, and whether a small test area is appropriate. Follow the clinic’s instructions about sun exposure and shaving. Avoid plucking or waxing before treatment if instructed, because the follicle needs to be present for the laser to target it.

Laser hair removal may also be discussed for recurring ingrown hairs or razor bumps, while conditions such as hirsutism or hidradenitis suppurativa need assessment beyond hair reduction. Read about [Alexandrite Laser](/technology/alexandrite-laser/), [Diode Laser](/technology/diode-laser/) and [Nd:YAG Laser](/technology/nd-yag-laser/) to compare the technologies.

Contact the treating clinic promptly if treated skin develops increasing pain, blistering, marked swelling, open areas, pus or rapidly spreading redness. Seek urgent medical help for facial swelling with breathing difficulty or a severe allergic reaction. Persistent darkening or lightening of the skin also deserves review. Ingrown hairs that are painful, draining or repeatedly returning may need separate care.

Which laser is suitable for my skin tone, hair colour and treatment area? What results are realistic for my hair pattern? How should I manage sun exposure, shaving and skin products before and after a session? What symptoms should make me pause treatment or contact you?
