Why is alexandrite laser used in laser hair removal?

The alexandrite laser emits a specific wavelength of light. Melanin in a growing hair absorbs that light, and the energy becomes heat that can affect the follicle and reduce its ability to produce a hair. Hair grows in cycles, so only some follicles are in a suitable growth phase during any one appointment. This is why a course of sessions is normally planned rather than relying on a single visit.

The contrast between hair pigment and surrounding skin matters. Darker, coarse hair often absorbs more energy than very light hair, while recently tanned skin may absorb more light and require postponement or different settings. A trained practitioner should assess skin tone, hair colour, treatment area, medicines, and tanning history before choosing parameters.

Follow the clinic's instructions about sun exposure and skin products. Shaving may be requested so energy reaches the follicle without singeing hair above the skin. Do not wax or pluck the hair shortly beforehand if the plan relies on a hair shaft in the follicle. Tell the practitioner about recent tanning, active skin irritation, medicines that increase light sensitivity, and any history of unusual scarring. Eye protection is required during treatment.

Mild redness or temporary swelling around follicles can occur after treatment. Contact the provider for blistering, severe pain, spreading redness, pus, marked colour change, or a reaction that is worsening rather than settling. Seek urgent help for facial swelling or breathing difficulty. Ask for an assessment before another session if the treated skin remains broken, infected, or unusually sensitive.

Ask whether alexandrite wavelength suits your skin and hair, how tanning changes the plan, what preparation is required, which aftercare products are appropriate, and what reaction should prompt a review.
