Mckenna Grace Debuts Red Hair at Miami F1 Event

mckenna grace debuted red hair on Saturday at the Celebrity Friends for F1 Miami Grand Prix Qualifying Race, turning a public appearance into a clear signal for her next screen role. The 19-year-old showed the new color in all white, with the look landing just as attention builds around her part as Daphne Blake in Netflix’s Scooby-Doo series.

On May 2, she arrived at Raising Cane owner Todd Graves’ F1 party in Miami wearing a white halterneck tank top, a matching long skirt, and white heels. She kept the styling tight: a watch, a simple silver chain necklace, rings, metallic earrings, and blush pink cheeks with a matching lip shade.

The outfit did the quiet work; the hair did the rest. Grace paired the red hairstyle with a clean white palette, which made the color change the most legible part of the appearance at the event in Miami.

She later captioned the post, “Shake and bake,” and the reaction followed fast. Comments included, “You look Scooby doo-per cute.”, “So adorable”, and “Capital cuteness.” The post had drawn 907.7K likes as of writing, a strong count for a single appearance post centered on a costume-adjacent reveal.

Netflix's Scooby-Doo Cast

The red hair tracks directly with the build-up to her role as Daphne Blake in Netflix’s upcoming live-action Scooby-Doo series, which explores the origins of Mystery Inc. That gives the Miami appearance a practical promotional edge: the look is not just a style change, but a piece of character rollout before the series arrives.

The cast around her includes Tanner Hagen, Abby Ryder Fortson, Maxwell Jenkins, and Paul Walter Hauser. With the ensemble now named and the character look already circulating, Grace’s social post serves as early public shorthand for the series’ tone before any trailer or release push reaches viewers.

For a 19-year-old actor, the move is efficient branding. The white-on-red contrast, the May 2 timing, and the Scooby-Doo link all point in the same direction: the red hair is doing more than filling an event photo, because it is now tied to the specific role audiences will associate with it next.
