Salon hair-straightening treatments can leave your hair looking sleek but may also expose you to toxic formaldehyde
(and can cost a small fortune). For a safe alternative that doesn't require a visit to your stylist, we like Living Proof Straight
(which doesn't contain silicone that can weigh fine hair down). This spray, which can be used on wet or dry hair, contains a humidity-blocking molecule that prevents frizz on even the muggiest days. If your hair is coarse, apply John Frieda Frizz-Ease 3-Day Straight
to it while it's damp and then blow-dry and flatiron to seal in the product. It requires extra effort, but the results last until your next shampoo.
