Bleach again or skip to toner?
I have been bleaching my hair for awhile but have naturally dark brown hair. I bleached my hair 2 days ago (only my roots and the regrowth) using powder bleach and a 20 developer ratio 1:1. My hair still has some dark yellow spots (i used purple shampoo after my bleach). I sectioned my hair off into 4 sections so two on each side and bleached my top half first and then my bottom half which is why i think underneath is so yellow bc I didnt let it sit long enough(my hair was so hot, i didnt want it to break off) also I always put a trash bag on over my hair once im done bleaching it until its time to rinse. ill add pictures in. Should I rebleach with my 20 developer using ratio 1:2 or developer 10 1:1 or skip to toner. Ill add all photos. Thanks!
