The color: Pastel Rainbow
Description: Nicole Richie, Kylie Jenner, and Hilary Duff have all been experimenting with unnatural hues and according to Hazan, candy-colored shades like powder blue, smoky lavender, sunshine yellow, cotton candy pink, and seafoam are here to stay.
Who it works for: These shades are best suited for someone who works in a creative field.
Technique: First, your colorist has to bleach your hair out to a very pale blond. Then, you can add one or a few different shades to create your own look. Rainbow strands are high maintenance (needs touch-ups about every six to eight weeks) and very damaging, so your colorist has to be careful about overprocessing.
