Also if you wear your hair perfectly straight, a human hair wig would be ok. Otherwise, some kind of heat would have to be used to style it. The same is true to a certain extent with human-synthetic blends. A curling iron set on LOW or WARM may be used on any synthetic fiber. Even though the blend contains human hair, one must defer to the synthetic when using heat methods for styling.
Hot rollers are ok too.
Although the the hair used in making human hair wigs is grown on a human head, it isn't like the hair growing out of your own head. After harvesting, it is chemically processed to remove the cuticle in order to minimize tangling, which can be a real nuisance with virgin hair. In addition, most of the hair is bleached out and dyed back for uniformity of color, then the hair is mixed and blended into whatever colors the company requires. So the hair has already gone through a triple chemical processing before it becomes a wig. For this reason, only shampoos, conditioners, sprays, and other styling products formulated especially for processed hair should be used.
