Stopped Propecia for 4 months. Huge hair loss. Resumed Propecia. Hair loss stopped. Will hairs lost regrow?

Question

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

Yes, you will need to maintain using Propecia to keep your results, but it's difficult to determine if this will regrow the hair you lost.  I suggest seeing a hair loss expert now to go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

My experience has been that hair loss will slow and generally some degree of regrowth will occur in situations like this where finasteride is restarted. However most men don't regain back "quite" the same density. It's usually pretty close though especially after just 4 months. Keep close follow up with your physician.

Thank you for your question. You may regain some of the lost follicles since the fallout was so recent. You may want to find a provider who can perform PRP injections in the scalp. This will likely give you a greater recovery of recently lost follicles. Usually takes a series of 3 to 5 sets of monthly injections.I hope this was helpful - Dr. Moore.
