Made to revive and restore blonde hair, this mask from Christophe Robin is an ultra-nourishing treatment formulated to restore hair's natural shade or refresh color-treated and highlighted hair between treatments. It glazes strands in a unique blend of iridescent pigments and Florentina Iris to help neutralize brassiness and yellow tones, revitalizing the brightness of blonde hair. After shampooing, apply to towel-dried hair from root to tip and allow to sit for 5-20 minutes depending on the desired intensity. Rinse thoroughly. Washes out after 3-5 shampoos. Does not cover greys. Upon first use, leave the mask on for 5 minutes to evaluate color intensity. Beauty Return Policy: We are unable to process returns for opened and used beauty products.
