Yes I am Nellie, and added to that my hair grows extremely quickly at the best of times, but these last few weeks my hair and nails have grown like mad. Glad you're pleased with your new hairdresser, it's always a worry going somewhere new.
Another brunette here with fast growing hair. I touch up my own roots though at about 6 weeks. I'm only really bad around the temple and hairline. My parting isn't too bad. How much longer that'll last though is another thing.
I don't think I could bear to have my colour fine properly every cut. I might have to go with that option at some point though.
