About 2 and a half months ago, I went to my hair dresser and she dyed my hair from a dyed blonde to a terracotta colour wasn't suppose tohave this happen. Went back and fixed it but the lady ended up doing it dark brown almost black.. which is fine as it has faded a lot. My natural colour is light blonde in the front and goes gradually darker towards the back to a light brown with some red.

I have roots showing at the front they are light blonde roots and dark brown/red for the rest of the hair. At the back of my head, can't really see my roots, they are a bit lighter but not that noticeble. I am trying to figure out how do I dye my hair back to it's natural colour so I don't have roots all over? Is this possible? As most salons will just cover your hair in one colour.

This is all demi-permanent colour.

Any suggestions?
