Just sitting in the hairdressers about to pay an exorbitant amount for a semi permanent hair colour. I have never tried to do it myself, is it easy? Any recommended brands? For info I have long dark wavy hair ... Quite dry at the ends, and fine, but there's lots of it. I have a few grey hairs near my ears which need covering up. I also like to go a shade or so darker... From dark-mid brown to a Zooey deschanel in new girl style colour. Any recommendations or advice?
