Can the hairdo 25" clip-in layered strait hair extensions be heat styled?

well what quality is the hair? if you get remy grade AAA hair (the best in my opinion) and you can straighten it and curl it or whatever you want. I got some of thoes at a href="http://www.hairextensionstore.biz" rel="nofollow"http://www.hairextensionstore.biz/a and they look really good. they have 24" and 26" i have the 24" and its the perfect length. I curl mine all the time and it looks great...
