If your hair feels weak, breaks easily, or has taken a beating from color and heat, the Diamond Strong collection is built to repair and reinforce it — sealing and rebuilding damage from the inside out so hair is more resilient, shiny, and frizz-free.
What it does for your hair: it strengthens with every use, fortifies the hair to prevent breakage, and restores resilience — all in a weightless formula that won’t coat or dull your color.
Key ingredients:
- Quinoa — a complete plant protein that strengthens and helps keep color 95% longer
- Hyaluronic Acid — deep, plumping hydration
- Cupuaçu Butter — rich nourishment for softness and resilience
- Camellia Seed & Manketti Kernel Oils — replenish, smooth, and add shine
The collection: Diamond Strong Shampoo and Conditioner to strengthen, repair, and restore as you cleanse and moisturize; Progressively Strong treatment to seal and repair damage with every application; and the lightweight Hair Repair Foam, formulated for weak, damaged, and fragile hair to bond and texturize with added volume and shine.
Best for: Weak, fragile, over-processed, or breakage-prone color-treated hair.
