After a colouration, current care technologies mainly seal the cuticle, leaving the matrix structure unattended which can lead to a lack of resilience, hair breakage and dramatic colour fade. When hair is adjusted to the optimal pH value of 4.5, the matrix around the cortex microfibriles is tightened and stabilised, keeping the colour pigments frozen deep inside the hair structure. In combination with Cell Perfector Technology, the hair surface is perfectly sealed, providing a long-lasting protection against external aggressions like water or blow-drying.

Diagnosis: Hair is colour-treated, highlighted or over-processed.
