Redken's Cover Fusion Low Ammonia is another salon administered, low ammonia hair dye option. It is supposed to cover grey hairs and revitalize hair structure. That it does effectively as my dyed hair is shiny and smooth even before treatment and that really doesn't happen with many brands. However, I noticed dye stains on my scalp that takes a few washes to remove completely.
This time around I picked a violet-black, it's black with hints of violet in the sun. I would say this is a hair colouring option for you if you don't do treatments after dyeing.
