Alexandrite and Nd:YAG laser hair removal

Alexandrite is strongly absorbed by pigment, while Nd:YAG interacts less with pigment at the skin surface and reaches deeper. This difference helps the clinician tailor treatment, but careful technique remains essential with either device.

Laser hair reduction works by heating pigment in suitable hairs and impairing the follicle's ability to produce hair. Dark, coarse hair generally provides a clearer target than pale or fine hair. Because hairs cycle through different growth phases, visible reduction develops across a planned course rather than from one exposure.

Hair growth driven by an underlying condition can continue even when treated follicles respond. For example, hirsutism may warrant medical assessment alongside cosmetic care. Reducing coarse hair can also lessen a trigger for ingrown hairs or razor bumps, although it does not treat every cause of inflamed skin.

Before treatment, report medicines, active infection, a tendency to scar, previous laser reactions and recent sun or artificial tanning. Follow instructions on shaving and avoid plucking or waxing when told, since the follicle needs a pigmented hair target. Arrive with clean skin and no unapproved fragranced or irritating products on the area.

Use cool compresses only as directed, cleanse gently and protect exposed sites from sunlight afterward. Avoid friction, vigorous exercise, hot bathing and picking until the initial heat and sensitivity settle, following the clinic's individual advice.

Small bumps and redness around follicles may occur soon after a session. Seek prompt advice for increasing pain, blisters, broken skin, marked swelling, pus, spreading redness or new patches of altered skin colour. Urgent care is appropriate if swelling affects breathing or swallowing, or if you feel acutely unwell.

Ask how your current skin tone, tan status, hair colour and hair thickness influence device choice. Confirm who performs the procedure, whether patch testing is advisable, which changes are realistic, and how maintenance is handled. If hair growth is new, rapid or accompanied by other body changes, ask whether a medical evaluation is appropriate.
