Do you apply to damp or dry hair?

I do dry. Add two ounces creme 20 volume peroxide developer to each bottle. It's a one for one proposition. I leave on for 45 minutes cause I want deeper color and to keep from turning to a gold blonde sooner. I want to keep it ash blonde longer. You can mix colors too, using this method. I do. Just keep to 1 ounce developer for one ounce color. Hope this helps.

With this take me from light red to blonde?

It should. My hair is a mix of light brown and gray. I use 9AA-BV 30 D flaxen blonde with 20 white creme developer with great results.

Need medium cool (not brassy) brown last used 7NN but still turns orange any suggestions?

To get rid of orange/red tones I actually use Schwarzkopf 0-22 in with whatever color I’m using.. I don’t use the whole tube, just a little bit with the color I’m using. With brown it gives a very beautiful ashy tone, which is what I love. I get it off of amazon too! Hope this helps because it’s the only thing I’ve found that gets rid of orange/red tones whether it’s with blonde or brown hair color.

What does D in the clairol hair color shade codes stands for? Thanks!

The D in the color name is another indication of the shade being an ash tone. If you have any other questions regarding the shade names please give us a call at 1-800-221-4900.
