We Can't Get Over This Olympic Artistic Swimmer's "GRWM" Videos

"As an Olympic artistic swimmer, our hair, for aesthetic purposes, needs to be out of our face and should be neat and nondistracting for the judges," Ramirez tells PS. "My hair in the video is the most typical way we style it for competition." The secret to that mirror-like, glazed finish? A gel-like substance called "Knox" — all of the athletes use it. "Unless they chose a decorative cap or something similar instead," she says.

Ramirez uses the Synkrolovers Premade Knox from her coach Andrea Fuentes's brand. "It's made of Knox gelatin, like what you would use to make Jell-O."
