Whether you're a bottle blonde or embracing the gray hair trend, a purple shampoo like L'Oréal Professionnel Serie Expert Silver Shampoo is a must-have. This color toning formula contains violet micro-pigments that eliminate brass to help restore cool tones to your salon color. Swap this with your regular shampoo once or twice a week for noticeably brighter, softer, and shinier strands.
