For “Natural and Rooty Color”

MALCOLM CUTHBERT Baja Studio, 20 Thompson St.,No.1C; 347-981-8333 Creating an intentionally grown-out-looking dye job without it looking too (unintentionally) messy or grungy is not as simple as it may appear. Which is why actress Emma Greenwell is so devoted to Malcolm Cuthbert, who counts FKA Twigs among his clients. “He is an incredible communicator,” Greenwell says. “He gets me, and he gets my hair.” By which she means: He creates “a natural and rooty color” for her (for $365); it grows out so well that she only needs to visit his Soho salon every three to four months.
