So, I've always box dyed my hair blonde (probably light brown naturally) but last 6 months or so my usual box has made my hair brassy. Tried purple shampoo ect. Tried a shade lighter but no good either. So tonight I used a one with bleach in to try and "lift it' - brassiness has gone but it is sooooo light! I'm pushing 50 and worried it looks trashy. Going on holiday on Monday to add to drama. Is it as bad as I think? How can I fix it?!
