hi just abit of advice on a root stretch need to do the root colour but I don’t need/want to tone the ends until after the roots are done and washed off (Hair has been previously over processed and looks unpredictable) I’m think of using the wella instamatic clear dust to create the blend from a 7/81+8/1 illumina root will the instamatic help create the blend with out adding any tone to the over processed bleached ends
