Hair color: How to go blonde from brown hair. Kim V0, master colorist to Hollywood’s most elite, took Katherine Heigl back to the Golden Era of Hollywood, creating at her request “a buttery, creamy golden blonde reminiscent of old Hollywood Glamour. ” Here’s how he achieved her look— which she loved!— at his eponymous salon at the Montage Beverly Hills this past week using Kim Vo Luxury Haircare.

Kim explains, “We used an on scalp oil bleach to achieve the desired level of rich, golden blonde and then gently weaved in apricot and honey highlights using balyage. We finished it with Kim Vo Brilliant Luster Glaze to seal the cuticle and preserve the integrity of the hair, creating a healthy and luminous shine. Katherine loves this glamorous old Hollywood golden blonde…she simply radiates!”
