Indola Colour Leave-In/Rinse-Off Treatment Mask is a caring treatment for use on colour-treated hair to nourish and reduce colour loss. Formulated with Silk Cocoon Proteins, it also combines Panthenol with Hydrolysed Keratin to replenish the hair structure and ensure up to 90% colour depth retention, even after 30 washes. Smart Pixel Technology restores virgin-like condition and brilliant colour vibrancy to the hair whilst in-built UV filters prevent colour fade caused by environmental aggressors.
