‘Tis the season for tousled beach waves! Which is all well and good when you’re actually able to make it to the beach, but we all know how difficult it is to replicate the look from home.

Arbiters of boho chic style, Mary Kate and Ashley Olson, have managed to nail the look, and they have a secret — a $3 hairbrush. Their hairstylist, celebrity hair guru Mark Townsend, shared the tip with People Magazine, which involves taking a boar-bristled toothbrush spritzed with hairspray to help calm flyaway while maintaining the look.

“What separates an Olsen from a woman leaving the gym is the details,” Townsend told People.

Townsend — who also works with their sister Elizabeth, as well as Dakota Johnson and Rachel McAdams — notes that the boar bristles are essential because normal plastic bristle toothbrushes may melt from the hairspray’s chemicals.

The Olsen twins are continuing to make their mark in the fashion and beauty world with their recently opened shop, The Row, in New York City. Their first shop opened in Los Angeles last year, and features their clothing and home good designs.

Might just have to stop by, after buying a toothbrush first, of course.
