I did DS hair today....mine will be next...roots were about 2 inches of grey......mixed up powder bleach with 30 volume peroxide, cover hair, roots last....after 20 mins rinsed off...towel dried hair....mixed up toner....used Majirel ash blonde 8.1 and a dash of Redken gloss toner , dont know shade as label came off,.. and 20 vol peroxide...applied....scalp was stinging a little but he persevered....and now it look great....nice even tones...now he has hair mask on to restore the condition...I have done my own hair previously so sort of know what to do..!!
