Which statement describes a key benefit of laser hair reduction?

• A. It can treat hundreds of hair follicles simultaneously
• B. It is always permanent after one treatment
• C. It works best on gray hair
• D. It is slower than electrolysis

Answer: (A)

Laser hair reduction uses concentrated light energy that targets pigment in hair follicles. Because the light can cover a wide area, hundreds of follicles can be treated in a single session, making the procedure quick for larger areas. This ability to treat many follicles at once is the main advantage, especially when compared with methods that address hairs one by one. Remember that results usually require multiple sessions and aren’t guaranteed after just one treatment, and the effectiveness depends on hair color and pigment—gray hairs respond poorly because they lack pigment.
