How to Switch Rainbow Hair Colors Without Totally Destroying Your Strands

For the vibrant shades in the model's locks, Friedman stuck to semi-permanent dye. She used a blend of Manic Panic (including Mystic Heather, Infra Red, and Pretty Flamingo) and Pravana (Too Cute Coral and black additive to deepen the colors).

While we were surprised that Friedman didn't use permanent color to create this look, she explained that it wasn't necessary. "Because the cuticle of the hair is so lifted [from the bleach], this semi-permanent color is staining the cortex." To give the shades a more natural appearance, Friedman massaged the dye into the model’s mane in sections, alternating hues as she worked.
