This specialized hair care product is formulated to neutralize unwanted yellow or brassy tones in blonde, gray, white, or highlighted hair. It deposits violet pigments to counteract the warm hues that can develop over time due to oxidation, environmental factors, or previous color treatments. A common application involves using it after shampooing, leaving it on for a few minutes, and then rinsing thoroughly.
Its significance lies in its ability to maintain the desired cool tone of lighter hair colors, preventing them from appearing dull or discolored. Regular use can enhance the vibrancy and overall appearance of treated hair, offering a simple solution to address the challenges of color maintenance. Historically, solutions to counteract brassiness involved temporary hair rinses; contemporary formulations offer a more conditioning and prolonged effect.
