Recovering from extreme dying
To recover from extreme dying you need to work in gradual stages. My goal was to go back to bleach blonde. In my ginger state I did not believe this could happen.
I died my hair a redish brown. I let this stay on my hair for about 3 months. I then died it a lighter brown kept that for a month and then bleached it.
The hair was slightly ginger again when I bleached it however persistent bleaching and not giving a crap kinda helped with this. After a year I was finally able to bleach it white/blonde again
