Hello. Thank you in advance for your help/feedback on this. I'm 45 years old. I've been taking Propecia for 20 years. Also using Minoxidil twice a day. I stopped taking Propecia for 4 months in June and had huge hairloss. I re-started taking Propecia in October and the hair loss has stopped. But the harm is done . Will all (or part of) the hairs that fell for 4 months will grow back now that I'm back on Propecia? And if so how long will it take to grow back? Or are they gone for good? Thank you
