The Science

Three phases. One precisely calibrated ritual.

BioHueZ is built on three intertwined chemistries — saturation, sensitivity, repair — developed and refined across forty-five years of laboratory work.

01Deep-Saturation
Greater
pigment penetration vs. standard kits

A dual-alkaline approach to low-porosity hair.

Compact cuticles resist single-stage alkaline lift. Our two-phase system opens the cuticle gently, delivers pigment precisely, then re-seals the fiber — restoring closer to native structure than conventional permanent dyes.

02Sensitivity
3,000+
sensitivity tests across 12 skin profiles

PPD-free, 98.6% irritation-free.

Three thousand sensitivity batch trials shaped the current chromogen system. Fifteen botanical actives — chamomile, aloe, centella — calm the scalp during processing rather than fight it.

03Repair
Less
PROTEIN LOSS AFTER 4 WASHES

Silk amino acids, in the same step.

Color and repair, historically separate, are now a single phase. Silk amino acids bond into the cortex during processing, measurably reducing post-color protein loss.
