I wanna have highlight for my dark brown hair with out damanging it at all help and i want it temporary....?

my hair has no highlight unlike my avatar!I wanna have highlight for my dark brown hair with out damanging it at all help and i want it temporary....?
highlighting and perming hair is already damaging hair. but if you want tips...i always use hot oil a few times before highlighting my hair, so it wont have split ends and damage my hair. if you want it temporary, you might want to dye it back to your normal hair color afterwards or get extensions. hope this helps!
