I dyed my hair dark brown today from a dirty blonde and parts of my hair turned blue. How do I fix it?
I would get another dark brown.
Definitely a different brand of dye.
Test on a small part of blue hair first.
3 parts lemon juice to one part conditioner. Mix together, slather on hair, let sit for an hour, towel dry, blow dry, then shampoo and condition as usual.
