Hey, I have sorta medium brown long hair and I was thinking about getting highlights before school starts. I want to get like a lighter brown or some dark blonde, but I want to get them done professionally so they don't totally kill my hair. Is it true that if you highlight your hair by yourself then you'll have more damage than if you get it done professionally? Because my hair is thick and dry, but I really want some more color in it. So I want to get it done professionally. Can someone give me some tips on what color to highlight my hair?? And if it will damage my hair or not?
