PROS: Lasers deactivate the hair bulbs, so eventually hair stops growing. However, some women need yearly touch-ups.
CONS: It’s expensive, and it can be done only in a professional’s office. “It requires about eight treatments, spaced a few weeks apart, and it doesn’t work on white, blond, or fine hair, because the laser targets pigment in the follicles,” says Fusco. It’s mildly uncomfortable (like snaps of a rubber band), and when not done properly, there’s a risk of thermal burn.
BEST FOR: Any hair on the face (upper lip, cheeks, chin, neck), except very close to the eyes.
