Well I did it. It went a bit lighter than I (or the hairdresser) expected. I got a half head of foils. It's pretty blonde around my face and top but the underneath is still auburn/brown. I don't mind it but I don't love it. I might need time to adjust I think! Next time I think I might get some put in that are a bit more caramel or honey. The problem with doing it this time is the hairdresser wasn't sure it would come out much different to my normal colour. Oh well, if I don't get used to it I guess I can either re-dye it or cut it all off.
