DD is in a show and needs to go from light brown brunette to blonde (she has long hair). She would prefer not to wear a wig, but equally would prefer not to dye it permanently as she'll have graduation photos etc later in the year.
Any ideas?? I assume a temporary dye wouldn't be strong enough to go from brunette to properly blonde, and that a spray in thing would leave long hair sticky and yuk. Dyeing it and then dyeing back to her natural colour would be a possibility, but would be £££ and not very good for her hair I guess (also not convinced she is THAT dedicated to the part)...
