green hair disaster! Help!

The only color that will cut green casts in hair is red, or going dark enough that the green is colored over.

Unfortunately, some brands of red hair dye contain copper and other metal salts to make the red more vibrant. When you use another peroxide and ammonia based dye or lightener over top, it causes the meals to react and the chemical reaction leaves a permanent green hue.

The only alternative to adding deposit-only red (to mask the green hue) and ending up darker is to lighten the be-jeepers out of it. It will still be green. But, it will be lighter, so you can cover over it with any light brown or dark blonde.

(Just remember, after bleaching, the hair soaks up more color than the box top indicates, so go 1-2 shades paler than the box to get what you really want).

Hello!
I think what happened was they (the salon) used color with not enough saturation to cover the orange so it washed out and left behind the dominate pigment.

I would bleach off the old color to a  level 7/8 and although it will be gold you could put a deposit only color over that.

It has to be deposit only or it will not work. Before the color is applied the hair has to be 100% clean. A level 7 or lower will cover.   I would use Wella color for the end result.

My daughter had dirty blonde hair with natural blonde highlights. she was 11 and had never colored her hair. She is an actress and played Annie, so we dyed her hair red. It was beautiful! When the show was over and the roots began to show, we decided to try and go back with the normal dirty blonde look for low maintenance and just get some highlights. After three attempts at the salon, the color would not change back. we ended up with orangy brassy hair. She did a double ash #8, a double ash #6 and some other things during the 3 times we visited. This was all spaced out about every 8 weeks or more. Last thing we did, we ended up with medium brown color with green tint throughout. We never got to the "highlighting" because we never got the color we were trying to get. She is 12 now and embarrassed to go to school. We need to cut this green! We tried baking soda and shampoo mixed as a paste, and we are going to get the brunette shampoo today. Any ideas on what to do without ruining her hair quality?
