Sabrina Carpenter stars in Redken’s new October 2025 ad, blending fantasy and humor to promote its A.B.C. Leave-In Treatment.

Sabrina Carpenter, Redken’s brand ambassador since December 2024, stars in a new October 2025 commercial that blends musical fantasy and humor to promote the brand’s A.B.C. Leave-In Treatment. In the ad, filmed in a hotel room, she struggles to reach the product amid collapsing luggage, then imagines a Broadway-style performance with dancing bellhops who chant “Leave it in!” to highlight its heat protection benefits. The surreal sequence features Carpenter in a feather-trimmed gown, followed by a giant conditioner-shaped man playing a saxophone, before she delivers the product’s key message: “The longer you leave it in, the better it feels.” The ad showcases her performance energy and Redken’s marketing campaign.
