Should i dye or highlight my hair?

I already have blonde highlights over my natural light brown hair.. but they're starting to come out %26amp; im thinking of getting more highlights to touch up or to have all of it dyed.. All of my friends said it would look good dyed but when my roots start showing i dont want it too look really fake and i dont want to have to keep dyeing it every few weeks.

So what would you reccomend..? and all of it would be done in a salon

Should i dye or highlight my hair?

If you don't want to dye your whole head of hair, I suggest getting a couple more highlights, so it looks more blonde.
