I think it;s fantastic. Third time i've had it done. Leaves hair straight and shiny, lasts for approx 9months and doesn't need any products or even brushing. My hair was very wavy at the root, not in very good condition and would go curly/frizzy in the rain or just damp air. My hair is shoulder length. I had it done at Rainbow Connection in Shrewsbury at a cost of �170.00. In case anyone is interested, my mom has also just had it done and she is completely grey and has a shoulder length bob style. She is also extremely pleased.
