Does anyone know how to fix my doll's frizzy split ends?

Hi, this is my first question, so I am kind of excited. XD Ok, I was wondering if anyone knows how to fix my doll's [this is how she looks like a href="http://www.google.com/products/catalog?q=Darice+Fashion+Doll+11.5%22+Blonde+Hair&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&cid=7322615705991245533&sa=X&ei=YU-0Tai-IdGhtwe5krjqDg&ved=0CDsQ8wIwAg#" rel="nofollow"http://www.google.com/products/catalog?q…/a ) if you can't click it then look up Darice Fashion Doll 11.5" Blonde Hair] really frizzy split ends. If you could tell me what type of hair she has too that'd be nice. I really don't want the ends to be frizzy anymore, so I can dress her up in the clothes that I will make her.
