How to get my hair light enough for a cyan-ish color?
I’ve been using 20v/30v developer & Clairol BW2 powder to try & lighten my hair. I’m aiming for a cyan sort of color, but with this last attempt my hair didn’t lift enough and, after dyeing, turned more into a green (this is 100% my fault because I didn’t tone it) with Danger Jones - Oblivion. Any suggestions on how to get it lighter to be more vibrant (and maybe a tinge less green)? I like the color of the roots & especially the color of the strands near my neck. Any advice/product tips will help!!
(Also I tried doing a raccoon tail strip so that’s why the left side has some dark “patches” I promise it was intentional.) (The rest was just a bad application job.)
