Those with naturally deeper strands, know that your time dabbling with rainbow dye is limited. "When clients have dark hair, I tell them, 'At some point, your hair will be too damaged to continue,'" Friedman explained. It's not the color that is harming your mane — it's the bleach. To lift the dark hues, you need to strip it of melanin (the molecules that cause pigment), which reside in the cortex of each strand.
"The action of bleach is essentially whittling each strand," clarified Friedman. This leads to loss of elasticity and breakage. She swears by Olaplex, a two-step strand-fortifying treatment. The Bond Multiplier is the first part of the formula, and strengthens your mane’s disulfide bonds, which are broken during chemical treatments. Friedman mixed this into the dye before applying it to the model's mane. She then used the Olaplex Bond Perfector after adding the dye, but before shampooing.
