usually u will shed some hair in the first few months,, this is a good sign that the med is reacting.. these hairs wil grow back... rogaine will stop ur hair loss, if for example u used it everyday for 2 year and didnt notice any regrowth but did notice u havnt lost any thats a result! some people expect much more from these products and quit resulting in the loss of hairs rogaine was keeping strong.. but saying that everyone in different and reacts differently to meds,, keep researching!
