I have been using this product for the past three weeks and I am not only seeing far less hair in the drain and in my comb, I am actually seeing 'baby hair' regrowth. I have tried SEVERAL other products, with little - or no success. The product label states that 3-4 months is required to see real results. This makes sense to me, since hair growth - and certainly re-growth, takes time. Since I am seeing results this early, I am very optimistic. When I purchased the product, I really only hoped that it would slow down or stop the hair loss, but now I feel like I may actually recover some of the lost hair. I will post another review in 4 months time to let you know what the longer term results are.
