I use the 2% liquid for women. April 2015 will be 2 years. I don't have facial hair from it.
You use it twice a day, every day for life.
It works by accelerating the hair growth cycle, from shedding to growth. The new hairs grow in fine and thicken over time.
If you put it on healthy hair (like a receding hairline or a thin area vs a wide part), that hair will shed. Not all of it, but a noticeable amount.
It takes at least 4 months to kick in.
I buy the Target version when Rogaine for Women is out of stock. It works just fine.
I have nothing bad to say about it. It gave me my hair back!
Get your flu shot...because I didn't.
