For most hair types
Inside every layer of the hair
Science that goes deep. Beauty that lasts.
- 1Cuticle · Outer layerNano-particles penetrate through the cuticle scales.
- 2Cortex · Middle layerThey reach deep into the cortex, strengthening and nourishing the hair structure.
- 3Medulla · Inner layerThey penetrate to the core, repairing and reorganising from within.
Regular treatment molecules are larger, so they stay on the surface and fade faster. Nano-sized collagen, amino acids and proteins reach the cortex for repair from the inside out.
The treatment, step by step
Wash. Blow dry. Seal.
- 01
Wash
Cleanses deeply and opens the cuticle, removing oils, silicones and buildup so the hair is ready to absorb.
- 02
Blow dry
Heat activates the nano-particles in the solution and opens the hair structure, so they reach deep into the cortex.
- 03
Flat iron
High heat (180–230°C) seals the cuticle and locks the treatment in for long-lasting results.
Lasts 4–6 months
Results that fade gently, never harshly.
