Hi, my hair colour is a natural dark brown and I have always used box dyes inorder to colour natural sun streak etc. About a month ago I got my first professional hair dye, a full brown rinse and blonde patches. I really like it but I have a formal event and think I would like to go back to full dark brown. I have heard that to change from blonde to brown you have to dye it redish first or it will go green? What can I do, would it be OK to buy a dark brown to put through?
Thanks heaps in advance to anyone who can answer
