Blonde Devotion

W’s beauty director shares her hair color secret.

I’m a bad blonde. By that, I don’t mean my blonde is bad (it’s terrific, thanks to my brilliant colorist Gina Gilbert), I mean that my blonde can sometimes act up and turn brassy when the color starts to fade. So, a few weeks after touch-ups, I use this treatment several times a week instead of my regular shampoo. Not only is the brass quelled, but the buttery elements of my color seem to shine more too. Win/win.
