I'd say be very careful about your pink bits, they may go green if you bleach up again. Best bet would be visit a decent hairdresser who's got professional qualifications and get a consultation. Failling that mix your bleach up and do a test on a bit of the pink stuff. For keeping the blonde colour use the John Freida range. Not cheap but it stops the blonde from going brassy. Trust me vodka and hairdressing don't mix. The last time my wife cut my hair after a few bevvys she forgot to put the guard on the clippers. It does grow again though, why not shave it all off, looks very sexy on a woman! Good luck
