Get the Formula for Sydney Sweeney's Blonde Bombshell Color

Celebrity colorist and Redken ambassador Tracey Cunningham (@traceycunningham1) is the magician behind the red carpet hues of many stars. This Oscars season was no different. Here, she shares her vision and formula for Sydney Sweeney, who plays Cassie on HBO's Euphoria

“On Oscar eve, Sydney and I spoke and she just wanted a little pick-me-up of blonde for the big day," she says.

"The pop of extra blonde completed her gorgeous look reminiscent of past movie starlets—she was giving me Marilyn Monroe vibes.”
