So I just heard that if you are getting extensions, the clip kind, not the sew in, you need to get the human hair ones if you want to curl the hair. Is that true? Human hair is so much more expensive, I am doing a real budget wedding where whole thing is costing less than 1,000. My hair is fairly thin just past shoulder length, I would love to have curls about 6 to 8 inches below shoulder length. What do you guys think?
