This Purple Shampoo is the perfect way to brighten up blonde hair, cancel out unwanted "brassy tones" or "brassiness" (caused by unwanted yellow, gold, and orange tones in the hair). If your blonde fades brassy, or your natural white, silver or grey hair, has a tinge of yellow to it... this Cool Silver (purple shampoo) will bring your hair back to a beautiful bright, cool, hue. Recommended to be used once a week, but is gentle enough to use every time you cleanse. Color safe, Sulfate Free, Paraben Free, and Vegan Safe!
