I have battled with red tones for years. I have used the brass free collection & it didn't work. I have used ash toned dyes, & it didn't work. The only thing from a boxed dye that remotely worked for me was a neutral or natural color.

I stopped using these darn boxed dyes, because they just don't work how you want them too, & plus, they were destroying my hair.

One thing you can try is a green manic panic gloss. I plan on trying this to get rid of my ugly red tones.

Other than that...I wish I had better advice for you. I want my golden light brown hair back & it's next to impossible with all the gunk (boxed dye) on my hair. I refuse to bleach again....I had to chop my hair to a bob length over a year ago because my hair was so damaged. Now it's a darker reddish brown, with almost an inch of virgin hair that's graying. It makes it pretty complicated to get where I want to be.....ugh!!
