Hi, I agree with the other comments. I had the same problem as you and over the years have spent time and money in good hairdressers only to come home and put my head under the tap!! However earlier this year my daughter took me in hand and insisted I go to her hairdresser, because I needed someone with 'imagination'. I was terrified, but came out with a lovely new hairstyle (the Fern Britton one!) and have been going every 4 weeks since then. I colour my grey roots myself as I am not confident to have him do them, although my daughters hair always looks lovely. A small point but I always go on Tuesday morning as I am the only one there and I tried a Saturday and it was chaos. Get a recommendation, go a few times and don't expect them to be mind readers.
Happy hairdo.....
