@First_Queens ok. I know this website http://daretohavehair.com/ has good hair. I haven't tried them yet but I've heard good reviews about them.
When I buy hair, I get Brazilian because it is the cheapest($65-$85 per bundle) and blends well with my hair. I usually get the body wave because its great holding curls w/ heat, can get really straight, and it can have a natural loose curl. If you want your bob straight all the time, get the straight. It holds a curl but not as long as the body wave. Malasian hair is just like Brazilian hair to me. It does the same things as Brazilian but most sites charge more.
