Perhaps I sound like a broken record at this point, but maintaining my blond is important to me. Over the last few years I’ve shifted my college highlights to something a bit more sombré (subtle ombré) in a dirty blond tone.

But recently I decided to kick things up a notch.

I booked an appointment to see Aura Friedman, the colorist for platinum strands at Sally Hershberger. Friedman is responsible for the lightened heads of Soo Joo Park, Sky Ferreira, and a ton of other cool-looking ladies, as evidenced by her Instagram. And hey, if Taylor Swift can go white-blond, so can I.

She assured me that I was in good hands and got to painting. As I sat with plastic wrap on my head and my trusty iPhone in my hand, we discussed how to maintain my soon-to-be lighter color. “It’s so hard,” I told her, “My color usually fades quickly and gets brassy after the first month.” Luckily, this wasn’t a problem that was specific to me. It turns out that a ton of Friedman’s clients struggle with the same blond reality.

Shampoo Less Frequently

“First and foremost, you want to avoid shampooing too often," Friedman says. "I recommend my blonds wash once a week. The less you wash it, the better it is for your hair and for your color. When you do wash, try to use cooler water—this helps to keep the cuticle closed and will allow the color to last longer.
