I would go to Sallys or some other type of supply house. They usually have well trained people that can help you choose the right products. If you want to go the grocery store route, get a brown one or 2 shades lighter than you think you want to be. do the all over brown first. wash, and dry. then do the highlights on dry hair. do babythin ones though or you will have roots next week!
