These Are the 10 Hottest Hollywood Rainbow Hair Hues, According to Stylists

The Color: Platinum Pastel Violet

Celebrity Inspiration: Louisa Johnson

Description: Louisa has an ultraplatinum base with a sheer wash of violet on top. “The very pastel violet tone requires you to either have very light blond hair, or you must prelighten to a pale blond first. Then you can add the sheer tone over the blond,” noted Papanikolas. “You will also need to come back to the salon for regular toners, as these pale pastel tones tend to wash out and fade really quickly.” High maintenance but totally worth it!

Who it works for: This coloring looks best on medium complexions with cool undertones. It can also work really well on fair skin as long as you have warm undertones.
