Permanent hair reduction using laser is commonly called what?

• A. Laser Hair Removal
• B. Chromophore
• C. Optical Cavity
• D. Delivery System

Answer: (A)

Permanent hair reduction using laser is commonly called laser hair removal. The name describes the procedure that uses a focused laser to target pigmented hair follicles and damage them enough to slow or stop future growth. This works through selective photothermolysis: the hair’s pigment (melanin) absorbs the laser light, heats the follicle, and damages it while leaving most surrounding skin unharmed. Because hair grows in cycles, several treatment sessions are typically needed to catch hairs in the growth phase for effective reduction. The other terms refer to components or concepts rather than the procedure’s name—chromophore is the light‑absorbing molecule (like melanin), optical cavity is part of the laser’s resonator, and delivery system describes how energy is directed to the skin.
