Review (4/5): They stay on!
These work well. I can't tell if they dry my hair better than a regular towel, but I can wrap my hair up with one of these and it STAYS PUT, which I definitely can't do with a regular towel. I'm not sure if I'm putting them on right, the instructions could have been a little more clear, but I suppose if it is holding my hair up and staying on, then I don't really have much to complain about!
