I bought the three-in-one brand and used it on my longest wig, and my Miku twintails. The first one, that is made from a ratty, coarse fiber, didn't get much prettier. I thought maybe it was because I didn't use enough, but when I used more, it seemed to get just more ratty looking. I hope the spray will at least help me untangle it after wearing. The tails on the other hand are a beautiful fiber, and they got even more easily manageable, and there are less flyaway hairs. Thank you for letting us know about this!
