- Size: 50 ml
- Price per ml: $1.50/ml (original $0.26/ml)
The why
A leave-in peptide treatment with SH-Oligopeptide-78 and Hydrolyzed Wheat Protein, designed for chemically or heat-damaged hair. Best for brittle, bleached lengths needing strength rather than daily hydration. Overuse can leave fine hair dry, stiff, tangled, or limp.
One minus
Protein-overload complaints: stiff, brittle, dry hair
