A Victoria's Secret Model Colorist Reveals the Secret to Sexy Brunette Hair

"Barbara Fialho has been rocking the natural brunette look for many years during her modeling career, but this year I wanted to do something different and striking. I wanted the color to make a statement, therefore I decided to balayage her and blond her up. Barbara works and travels a lot, [so] sometimes her hair can get really dry from all the styling and also the water changes in different countries. Therefore I try not to process her hair even more with color and highlights."
