fotogrrl, just a few more things.
The product I use is for men - but they use it twice a day. My derm. recommended that I use it once a day so that I would get only the right amount.
The men's product is the foam and it is much easier to use than the women's product which is a liquid. It gets all over my hair by the way, but nothing bad happens.
You have to use it for months before you see a result.
