How do i do highlight my hair without buying special products?

i want to highlight my hair a caramel color!!How do i do highlight my hair without buying special products?
To highlight it in a caramel color you will have to use a highlighting kit. There is no way to highlight your hair without one, apart from some questionable methods that would probably not end up in a nice caramel color. I prefer using the herbal essences highlighting kit in caramel, their brush is really easy to use and it always gives great results all around.
