Cap or Foil highlight my hairstyle?

I have long medium to dark brown hair, quite thick and I am going to the hairdressers this Sunday. I don't know whether to have the cap (all over highlights and cheaper) or the foils (top half of hair for same price as cap)?? I don't like the idea of the cap, as I don't imagine it will have much effect but will only half a head of foils look right? If anybody could get me any pictures of a half foiled head that would be great (preferably on darker hair like mine). If not, what would you have done? Foils or cap? (just for your info, a full head of foils would cost me an extra 拢30).Cap or Foil highlight my hairstyle?
Especially with the length/ thickness of your hair you want to foil highlight it. Cap is not even meant for longer hair, it can break off alot of it in the process. I think you would be impressed at what is called 'half' head of highlights done by foil is still a dramatic effect, plus it allows for larger pieces and better placement!Cap or Foil highlight my hairstyle?
i would get the cap because with thick hair only half will feel like nothing and only getting half done can look odd
