My roots are just over an inch long now and very blonde. I’ve been using ‘sunkiss jelly’ to gradually lighten my hair and I think it’s working :) it’s now a very very light copper so blends in really well with my roots. I’ve also been making my own bluey / green toner which is helping to neutralise the orange. It’s a couple shades off from being blonde which is very frustrating but I have to be patient! Hopefully by september it will be light enough to go over with an ash blonde hairdye.
