Riverdale's Vanessa Morgan Stole This Genius Beauty Hack From Costar Madeleine Petsch

Toni Topaz is Riverdale's Pretty Poisons leader, a fierce River Vixen, and one half of what fans call "Choni" (her relationship with Cheryl Blossom . . . obviously). Vanessa Morgan, who plays Topaz in the hit CW show, told POPSUGAR that you can expect a moody new hair change from the character in the series's most mysterious season yet.

"I added purple to my hair," she said. "In the first few episodes, it's kind of subtle. If you go through the season, you're going to see more purple in [my hair] with the pink." She explained that her hair pros for the show created the look using a spray for season four's earlier episodes before deciding to use clip-in extensions.

Prior to this change, Morgan's character only had sections of pink in her caramel-colored curls.

Morgan added that Madeleine Petsch, who plays her love interest on screen, is a source of solid beauty advice IRL. She picked up a genius trick to groom her brows from Petsch: spraying Tri Tri Aerogel Hairspray ($22), a flexible-hold hair spray, onto an eyebrow brush before brushing through them.
