High temps from blow-dryers and flatirons can damage hair, causing a whole host of issues—frizz, flyaways, split ends, dullness—in the long run. But you probably already knew that—just like you probably know a heat protectant serum or spray is one good way to prevent your styling tools from wrecking your hair. But the thing about heat protectants is they’re not the most gratifying beauty product to use and really…if you’re anything like me, they tend to wind up collecting dust in your bathroom, because really, who can be bothered with adding one more step in the morning? Olaplex No. 9 Bond Protector Nourishing Hair Serum is different—it’s one heat protectant you can actually look forward to using, because it helps make hair shinier while it works to protect against heat from styling tools—a win, win! Smooth it over damp, towel-dried hair, from the mid-lengths to the ends, then run what’s left on your fingers over roots. It gives hair a boost in the shine department, while helping keep it healthier overall.
