It's slow going; I've been using it for 3 months, and I can see some new hair growth, especially on my widow's peak, where it's easy to see, that has definitely filled in with some fine new hairgrowth, The top of my head still looks sparse, but I'm hoping the same hairgrowth is happening there and I just can't see it yet. I'm carrying on and hoping to really see results in the next 3 months.
