About a month ago, I went to see my amazing hair colorist Jay with a recent photo of Rachel Bilson clutched in my hand. "I want that," I said, gesturing to Bilson's hair, which was dark at the roots and then gradually lightened all the way to the tips into a honey-ish brown. Jay, who specializes in a hair color process called Balayage, went to town and I walked out of the salon with the perfect summer hair color for a low-maintenance gal -- long darkish roots which eventually lightened to a sun-kissed shade at the ends. The more my hair grew out, the better the style would look -- what woman wouldn't love that?
