The slicked-back bun has become one of the chicest hairstyles of late, and Sofia Richie has the look nailed down like no one else. The 25-year-old media personality revealed on TikTok earlier this month exactly how she achieves her “sleek, lazy girl bun,” but she also dished out a number of additional haircare tips along the way.

We took note that one of the products Richie uses in her routine has a number of other hair benefits besides just hydration—and in fact, it’s one that she credits with helping her hair to grow.

“I would say in the beginning of COVID, my hair length was like, stuck here,” Richie stated in her Sept. 2 TikTok as she pointed to her shoulders. “From like all the bleaching, all the dyeing, my hair length was just stuck here. And over COVID, I was like, I’m really gonna try instead of using like a gel, I’m gonna try like a hair mask. So, I tried the hair mask... [and] I’m convinced it’s the only reason why my hair like grew lusciously over COVID.”

Richie’s preferred hair mask, the Christophe Robin Regenerating Mask ($69) is safe for color-treated hair and detangles while it conditions. It’s designed to smooth the hair and eliminate frizz, so you get plenty of benefits for the somewhat high price point.
