Summary
The top community recommendation for banishing brassiness in highlighted or color-treated hair, using both blue and violet pigments for a dual toning effect. More effective than standard purple shampoos.
Consistently praised as a holy grail by Reddit's hair communities for everyday softness and hydration. Users who stray always come back to it.

Cons

Our take
Purple shampoos are hit or miss, but Matrix Brass Off with its blue and violet pigment combo is the one Reddit actually recommends — it works where others disappoint.
This is the shampoo people keep returning to after trying everything else — that loyalty tells you everything you need to know.
