Half off hair highlights with genius colorist

Do you have one thing that you splurge on no matter what? Therapy, yoga, Mast Brothers chocolate? Mine is highlights from Borja Cau, a hair colorist in midtown Manhattan who has a way with blond the likes of which I’ve never seen elsewhere. (She does other colors too.) Where lesser talents rely on foil, she uses a technique called balayage, which involves freehand painting. She says it adds depth and looks more natural than foil; I just know she’s phenomenal — I haven’t had a single miss in more than a decade. From Nov. 25 through December 3, she’s offering 50 percent off for new clients. Even if you’re already committed to a colorist (please share below!), she’s worth cheating for. Here is her Facebook page, and some of Borja’s Citysearch reviews from similarly smitten clients.
