New hairdresser. Had a colour on today which usually takes 30 mins (to develop, not including time it takes to put it on) unless i go under heat then it takes 20 minutes. Today she left me 1 hour 15 minutes and did two other clients in-between. I know it doesn't take 1 hour 15 minutes for my roots to set. Agh! Was in there 3 hours in total!
