My hairs been highlighted since I was in 8th grade...about 9 years ago...the color is usually permanent...and you do have to keep up with it id you choose a light color...but your roots will blend in much better that if you just dyed it! I love them, all my friends do them...it's just how I've always been. Here it's $70!! Let me find a picture of mine...
I don't know if you can see them, I need to have them touched up! Please excuse my nose...i really hope it's not that big...anyway, this should give you a general idea...my hair is light brown...i did ALOT of blonde highlights!
