Wildly popular HBO show Game of Thrones returns this Sunday, and the anticipation is real. While you could do this living-room-friendly GoT-themed workout, one way to truly show your fandom is by giving your hair a white-hot, Khaleesi-style look.

In our latest Locker Room Look Book, New York Pilates co-founder Heather Andersen (who serves up pure Daenerys Targaryen vibes with her silvery-blonde, mermaid-length strands) is sharing all her bleached-hair know-how—and as a color-treated convert for nearly six years, she’s got seriously smart tips to get around the chemically processed struggle.

Yep, it is possible to have waist-length, Khaleesi-white strands—without the breakage.

Yep, it is possible to have waist-length, Khaleesi-white strands—without the breakage. To do so, Andersen opts for a single process, which means a bleach application without a toner. Toner’s designed to remove yellow hues, she explains. But it also means subjecting your scalp to an extra round of chemicals—so the Pilates queen turns to other methods to nix brassiness instead.

Plus, the former dancer shares how often she actually washes her hair (as an always-moving fitness pro, the answer might surprise you), and her genius trick for disguising greasy roots. Throw on a crystal crown, and you’re ready for the Iron Throne.
