When is laser hair removal recommended for hypertrichosis?

Hypertrichosis means hair growth that is excessive for a person's age, sex or body area. It can occur on the face, arms, legs, back or other regions. Laser energy targets pigment in the hair follicle, so darker hair often responds more readily than very light, grey or white hair. The treatment reduces regrowth rather than treating every possible cause of excess hair.

Arrange an assessment before booking sessions, especially if the hair appeared suddenly, is spreading, or began after a medicine change. Tell the clinician about tanning, medicines, keloid scarring, cold sores and previous reactions to light-based treatment. Avoid plucking or waxing for the interval advised, because the follicle needs to be present for the laser target. Follow the clinic's shaving, sun protection and aftercare instructions.

Seek medical review promptly for sudden, rapidly increasing hair growth, new severe acne, voice deepening, scalp hair loss or other hormonal changes. These features may need assessment before cosmetic hair reduction. Contact the treating clinic for blistering, marked swelling, worsening pain, or skin colour changes after treatment.

Ask whether the hair pattern suggests an underlying condition, whether the laser suits your hair and skin, how many appointments may be needed, and how pigment changes or irritation will be prevented.
