Review title is no idea if it is working, roller ball would be better [SEP] I have rather light hair, although with some bristly whiskers. I can't really tell if this is working, will reply when I have used it more than 2 months. I am using this on my chin and neck and a wide rollerball would be better to apply than the spray format, even with the problem of a rollerball needing to be angled etc.
