Its only been over a week and already I can see them making an appearance along my parting. I recently had it highlighted hair but it was so damaging to my hair that I decided to go back to brunette. It was quite dark as the hairdresser used a medium brown however its faded and I've got used to it it now and love the colour. It looks shiny and feels so much healthier its just the dam grey that is poking though help!!! How often do you need to dye yours?
