Is 20 volume peroxide right to go with Wella color charm (Very dark brown) hair colour?
My natural hair colour is dark brown almost black according to the whella colour chart the Wella very dark brown 211/2N is the closest match to my natural hair colour.
The majority of the new hair is still dark with lots of grey dispursed throughout that needs to be covered. I have about 3 inches of new growth to cover.
I want to make sure is it ok and safe to use 20 volume developer/cream peroxide with the wella color charm hair colour to cover my roots? Is this the right volume to use as I do not need to lighten my hair could I get away with a 10 volume?
20 volume peroxide is correct. 30 volume is used to make hair much lighter as well as 40. but 10 volume … i have no idea what that’s for, i’ve never seen anything in a beauty shop that uses 10 volume. but yes, use 20. good luck!
