Works well to cool brassy colors and bleach disasters
My hair was bleach ravaged from wanting to transition from box dye jet black to a softer tone. Turned bright orange after trying to lighten it to the point that not even the salon could tame it. I’m finally back in the softer brunette palette but still have a few inches of bright orange to keep cooled until I can finally cut it all off (PS DONT EVER BOX DYE ANY COLOR LET ALONE BLACK). The product is amazing at cooling off the tone for at least a couple weeks and lasts much longer the longer you have it in (I have been guilty of doing an hour when it was very orange and it worked like a charm).
