What should you know about hirsutism and laser hair removal?

Hirsutism is excess coarse, dark hair in androgen-sensitive areas. Laser targets pigment in the hair follicle to reduce future growth, but it does not diagnose or correct a hormonal driver. New hair can continue to appear if the underlying condition remains active, and response varies with hair colour, skin tone, treatment area, and the selected device.

Alexandrite, diode, and Nd:YAG lasers use different wavelengths and may suit different skin and hair combinations. A trained clinician should choose settings after examining your skin, hair, medicines, and tanning history.

Have hirsutism assessed when hair growth is new, rapid, widespread, or accompanied by acne or menstrual changes. Before laser treatment, disclose recent tanning, pigment-altering medicines, active skin disease, and a history of dark marks after irritation. Follow instructions about shaving, sun avoidance, skincare, and treatment intervals. Do not pluck or wax when the plan depends on the follicle being present.

Pause treatment and contact the provider for blistering, severe pain, spreading redness, pus, or persistent pigment change. Seek medical assessment for rapidly increasing facial hair, deepening voice, severe acne, irregular periods, or other sudden hormonal symptoms. Ingrown hairs, razor bumps, and recurrent inflamed lumps may need treatment alongside hair reduction.

Ask which laser fits your skin and hair, who will perform the treatment, how a test area will be assessed, and what aftercare reduces burns or pigment change. Clarify whether you need hormonal evaluation, how maintenance will be handled, and what symptoms should stop further sessions.
