Can i color over blond highlights?

Sara

A few months ago my hairdresser dyed my hair my natural color to cover my greys and also put foils in my hair. Now after washing it more and more they have become increasingly more blond and I really don't like them but can't afford to get it dyed professionally right now. If I attempt to dye it myself with a box store dye would this work or completely mess my hair up? If it would be ok to do my own what color would be best to use? Thanks!
