Click to see the full answer.What happens if you put too much developer in hair dye?
If you put too much developer, you will be lightening the hair but not depositing enough hair dye and the color won't last.The mix for high lift colors is 1 part hair dye to 2 parts developer.The correct mix is 1 part developer to 2 part toners.
If you mix Paul Mitchell the color levels 1-10 and the Ultra Toners with Cream or Clear Developer in equal parts, you will get a1:1 ratio.
