This specialized shampoo from Tecna is formulated to effectively neutralize unwanted yellow or brassy tones commonly found in blonde, bleached, or grey hair. It works by depositing subtle cool pigments to reveal a clearer, illuminated blonde or silver shade. Ideal for maintaining the vibrancy of salon color treatments or naturally cool tones, this product helps restore the desired chromatic balance, leaving the hair feeling clean and looking brighter. Use regularly as part of your hair care routine when yellowing is noticeable.
