Dying brown hightlighted hair back to its natural colour?
I have mid-brown hair which has been highlighted with a few shades of blonde. i would now like to go back to my natural colour and was planning to do this with a diy kit at home.can i follow the instructions of the box or do i need to prepare my hair for this first - would not want the highlights to show through the redyed colour or for those sections to fade quickly.any advice would be great!
