19 Apr Flatiron Your Hair
Ever notice how straight hair looks almost incandescent when it catches the light? That extra-glossy effect isn’t an illusion, says dermatologist Jeannette Graf. “Flat-ironing helps ruffled hair cuticles lie flat, which creates more surface area to reflect light,” she explains. Just be sure not to fry your strands: Only iron bone-dry hair, use a gliding motion, and choose ceramic plates to protect against excessive heat.
