I hve only recently gone brunette after 10 years of getting blonde highlights. Hairdresser did a great job but she only put a semi in so the blonde is starting to come through already. I can't afford to keep going to the hairdressers especially at £40 a pop so have bought a Perfect 10 dye kit, but I've noticed it says permanent.
I'm happy staying brunette for the foreseeable future so would this be ok to use?
