>>8691837Try to find items from sellers with a good range of reviews unless you want to take a chance. I bought two wigs from a place that seemed shady and they ended up being really roomy and better than the 'official' ones but I bought from Taobao so I'm not sure if you are going to buy from Arda, etc.
There's heat-resistant fibers, kanekalon, regular 'silky straight' kanekalon, and the coarse kind used for ethnic hairstyles like yaki or jumbo braid. If in doubt ask but they usually have a description on the shop/item.
Off hand Epic cosplay wigs are good for styling but I have no idea how heat resistant they are. Arda are also good but the long ones tangle worse than two black girls fighting with weave and there's a few others (such as Japanese sellers.)
I personally use Arda and Taobao because I have a big head.
