How can I get my hair color like this with a box dye?

looks like you need some caramel golden tones... maybe buy a ash blonde/golden blonde and do a strand test to figure out how long to leave it on for the get the right colour I'd say 2 thirds of the time it says on the box maybe less depending on how light/dark your hair is.. then do it in even strands through the hair either in foils or a cap although a cap may make the strands too thin, Have a look on youtube how to do foils and get a friend to do it for you as the back is quite hard to do yourself.
