The Olsen Twins Just Made The Toothbrush Cool

The Olsen twins have been on the road promoting their new Nirvana fragrances, and along the way, the usually quiet twins have been dropping little news items, particularly about their beauty routine. We've learned that Mary-Kate feels like she just learned to brush her hair, while Ashley possesses ninja-like stylist skills. And, now it appears that the secret to their infamous brushed-up brows is an old makeup-artist trick. The tool to the perfect brow is — wait for it, kittens — a flat toothbrush.

Byrdie got the insider 411 on the twins' top makeup tips for looking Olsen-esque and effortlessly edgy. Ashley dished that a flat toothbrush plus some Anastasia Clear Brow Gel is all you need to steal their brow mojo. As far as we're concerned, and since the girls have been rocking this look for years, this is the OG of eyebrow advice .

Check out the article for the rest of their makeup secrets (the artfully smoky eye tip is kind of genius), and maybe you, too, can steal some of that Olsen mojo. We just have one question: How is it that Mary-Kate was in on that eyebrow-brushing trick before learning how to brush her hair? Clearly, your brows frame your face, but your hair, you know, frames your entire head. Priorities, people. (Byrdie)
