The Olsen twins are known for many art + culture contributions: their trademark saying from Full House, their epic teen movies, their award-winning fashion lines and, oh yeah — their killer sense of style. But while their clothing may be mostly curated by them, they’ve turned to celebrity hairstylist Mark Townsend for some hair help for years. And, lucky for us, he’s gone ahead and shared the one easy hair hack he always uses on the iconic twins.

While sharing some of his pro tips with People Magazine, Mark says, “You know what separates an Olsen on the red carpet from a woman leaving the gym? It’s all about the details.” So to achieve that perfectly tousled look MK and Ashley are known for, Mark finishes the style by spraying a toothbrush (he claims a natural bristle brush is key) with hairspray and then using that to gently comb + tame all those flyaways and broken hairs around the part and face.

This actually isn’t the first time Mark has made this pro-tip known. During award show season he did the same with Bella Hadid before she walked down the red carpet. He says none of his celeb clients leave his chair without his not-so-secret finishing touch. And now it looks like we won’t be leaving the house without it either.
