Review (2/5): i really wouldn't bother
i should have known better, but this was really not a good idea. these caps never fit properly so that the whole hair shaft is not completely exposed, the pointy little hook is painful when it digs around on your scalp to find hair to pull out, and when it gets hold of a hank, some of the hairs might be laying in different directions under the cap so that pulling them through hole is arduous and frustrating and it hurts. If your hair is too short, it can easily slip back inside the cap once you've got it pulled out and, if your hair is too long, it is even harder to pull through the hole. In my opinion this is not a DIY job. Go to a professional.
