I will never get used to how beautiful Drew Barrymore is or that I get to do her hair color.
To achieve similar results, all you need is Redken Flashlift. Frame face with babylights using 20 vol and 1/4oz Olaplex. To keep the hair looking natural, I never put base around the hairline. In between foils, paint with ShadesEq 06n+06nb to darken clients hair. While processing, balayage the ends, rinse and reboot over highlights! I then cleargloss all over with Olaplex for 20 mins and done.
