There is really no way to know the answer to that question without knowing your genetic inclination. If you are inclined to male pattern balds through genetics, then you will continue to loss hair once you discontinue Propecia. Hair loss is a cumulative effect of DHT scarring the androgen receptor on the hair follicle. So, while propecia will slow that process down on cycle, it will continue to occur after cycle naturally after you stop taking propecia.
