I've been really happy with the ANAZE Colure Silver Grey Toning Shampoo. It does a great job of reducing yellow and brassy tones without making my hair look dull or overloaded. The shampoo lathers nicely, has a pleasant scent, and leaves my hair feeling clean instead of dry—which can be a problem with some toning shampoos. After a few washes, my silver/grey color looked brighter and more refreshed. A little goes a long way, so the bottle lasts quite a while. I'd definitely recommend it to anyone wanting to maintain cool-toned blonde, silver, or grey hair.
