Schwarzkopf (Ph 4.5) Color Freeze Silver Micellar Shampoo 250ml

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.
