Going from dark/medium brown to blonde

I have naturally light brown hair that was dyed quite dark brown at the top and bleached at the ends. Since February last year I've been getting highlights (mostly full head) if you want a nice depth highlights is the way to go in my opinion! My hair was a really nice shade in between brown and blonde too - a goldeny blonde/ brown! I am fully blonde now so yes it did take nearly a year but I think it was worth it - If you try and do it in one go your hair usually turns orange so it's better to do it in stages!
