[kirstyLoc]

Hi, I'm having my hair done at a salon I used to work at as a Saturday girl they mainly deal with older clients so want to make sure I'm going to get the result I want! My hair is currently in ombré style and want a full head colour of a creamy ginger colour! I've purchased Loreal Inoa 7.43 copper golden blonde from the warehouse. and want to make sure I get an even colour all over! What is the best way to do this?
