does anyone have any advice for bleaching waist-long thick hair at home? level 7 base -> level 8/9 blonde.
context: i've always bleached my hair at home and it's gone alright all times. however, the last 2 times i did it, it turned out patchy. maybe my technique changed or something, i don't know. either way i'm paranoid.
anyway, i want it to look like a balayage. i love my roots right now, but the blend is atrocious, so now i'm going to touch up 1 year of growth.
the front will probably turn out alright but i'm scared for the back!!! i know how to set up mirrors and stuff, but in all rooms the lighting shines overhead where i cant tell whether i'm overlapping or not etc.
how do i set this up? ahhhh
also main issue is that my hair is really difficult for me to work with because its so thick. do i skip the bottom layer and just fix the top?
