What to expect from laser hair removal for hirsutism

Hirsutism is unwanted coarse hair growth in areas where it may be influenced by androgen hormones. Laser energy targets pigment in the hair shaft and heats the follicle, so hairs in an active growth phase respond best. Hair may shed after treatment rather than disappear immediately, and regrowth can become finer or less noticeable over time. Hormonal drivers can continue to stimulate new growth, so laser treatment may reduce hair without addressing the underlying cause.

At the consultation, disclose medicines, recent tanning, pigment changes, scarring history, and any hormonal symptoms. The clinician should match the device and settings to your skin tone and hair characteristics, with eye protection during treatment. Avoid tanning and follow the clinic's instructions about waxing, plucking, shaving, and topical products. Mild warmth, redness, or swelling around follicles can occur for a short time. Use gentle skin care and broad-spectrum sun protection, and do not pick treated areas.

Contact the treating clinic promptly for blistering, marked swelling, increasing pain, pus, spreading redness, or a persistent change in skin colour. Seek medical assessment for rapidly increasing facial hair, voice change, severe acne, or irregular periods, because these features can point to a hormonal condition that needs separate evaluation.
