Camila Mendes Swears By This Popular Treatment for Frizz-Free Hair

Camila Mendes is an open book when it comes to her beauty staples. She's revealed her favorite mascara for feathery lashes, her go-to peel for a brighter complexion, and even her preferred deodorant. But somehow, there's still more for the Riverdale star to share, including her hairstylist-approved hack for a frizz-free mane.

While you might be expecting something unusual—like mayonnaise, LED lights, or camel milk—Mendes' trick isn't all that extreme. She simply applies Olaplex No. 6 Bond Smoother Reparative Styling Creme after her shower to get perfectly smooth air-dried waves. (The actress also swears by this $10 hair product.)

"My colorist, Matt Rez, recommended this to me about a year ago as a more long-term way to tame my frizz," Mendes told The Strategist. "It really seals my hair in a beautiful way. It also absorbs nicely—I don't feel like my hair has too much product in it or looks too styled or unnatural."

The actress sums up the effects of the leave-in treatment pretty efficiently: It hydrates hair to eliminate frizz. But of course, there's more ~science~ happening behind the scenes. The lightweight cream contains Olaplex's patented bond system, which repairs and protects damaged hair at a molecular level.

The formula, which arrives in recyclable packaging, also skips unnecessary add-ins, like sulfates and parabens. That means it's safe to use on all hair types, including fine strands and curly locks. Plus, the formula can also be used on color-treated tresses. In fact, it's often used on over-processed hair to strengthen it from within.

Even better? Its frizz-eliminating effects last for up to 72 hours after application. So even though Mendes is impressed by the flawless look of her wavy hair right after it air-dries, the lasting smoothing effect is the product's true claim to fame. (Don't forget to use a microfiber towel for even smoother strands.)

Mendes' stylist isn't the only one who loves the Olaplex treatment. It actually has more than 80,000 "hearts" on Sephora from shoppers that consider it a "miracle in a bottle." Not only do they say that the treatment leaves hair feeling undeniably soft, but it even reduces blow-dry time.

I don't know about you, but this cream is going right into my (virtual) shopping cart. Now it's time to check out Mendes' other recommendations, like her affordable $3 eyebrow brush and absolute favorite sunscreen.
