In most salons it depends on how much the will have to use and how long your hair is. But there are other salons that will charge you a flat rate. You can do this yourself ya know? You can go to any beauty store such as Sally Mae. Much cheaper to do it yourself! By the way, I know of others that used powdered Koolaid packets to give their hair these bright colors as well.
