Rated 1 out of 5 by from Very unhappy I was very unsatisfied. I ordered a red and got a copper. Didnt know that it wouldnt turn out to be red until i rinsed my hair and of course by then its too late. You cant wash it out.

Rated 5 out of 5 by from Excellent when used right! When bleaching don’t let it get to hot it develops fast. Monitor the heat from your head. I’m not a professional just a helpful hint.

My hair is currently a black rinse. I have very thick dark hair looking to go a Cooper red but not too bright. Can't decide between 30 or 40.

Asked by: Tee Tee R
Always try the weaker volume first, unless it's box black dye. Do it gradually and try some olaplex. Remember slow and gradually

This developer should be good to mix in with the red dye. The higher number developer, the lighter it will lift

How to use the developer 

Asked by: Karolina
You can use it with lightener ("bleach") or with permanent hair colors, just follow the directions of what product you're using. You don't use developer by itself, it's meant to be mixed.

Which numbered oreor crème developer lightens brightest with Loreal high performance quick blue?

Asked by: conniepa
The higher the number, the higher the lift! The darker your hair is the higher the lever developer you will need.

I have dyed my hair natural black for years. I have not dyed it in at least 6 months and have grey regrowth of 3-4 inches

Will this #40 developer when used with a white blonde dye be able to lift the old black dye
Asked by: Marcella Byrne
I would opt for bleach rather than a blonde dye. Use 40 vol. developer and a bleach powder. I suggest Wella's. Your hair may turn a brassy/orange color, but you can use a toner to correct this. Wella makes a great toner also. Keep the bleach about a half of an inch away from the gray and wear a shower cap to retain heat for maximum lift. Let your hair rest for at least a week before using any dyes. There are some great tutorials on youtube that would help! Also, ION makes a great Olaplex copy cat that can help prevent any damage from the bleach. It's called Absolute Perfection and you can just mix it in with your bleach.
