So I have dyed my hair many times before. But, I haven't dyed it for like 9 months now. My roots are completely in. My natural hair color is sandy blonde/dark blond. I want to dye it a light golden blond color which I did one time and it turned out really nice. I'm just nervous because I've had accidents before and would hate for it to turn out bad. Any advice? Do you think it'll be fine since I've left my hair alone for quite awhile now?
