Q: Hi. I am 52 years old and wish to know if Propecia will work for people my age. I have started losing some hair a couple of years ago and it’s thinning out. Thank you very much for your help. — K.E., Boca Raton, FL
A: Propecia (Finasteride 1 mg) can hold on to hair at any age, but works best to re-grow hair in those who are younger.
The reason is that finasteride works to reverse miniaturization (the thinning and shortening of hairs due to DHT). Younger patients, with early hair loss, generally have more hair in the early stages of miniaturization where the changes are readily reversible.
Older patients are more likely have more advanced miniaturization or areas that are totally bald and will thus not regrow with medical therapy.

- What is your Opinion of the Companies that Advertise Hair Loss Solutions like Hims and Keeps?
- Can Rogaine Cause Miniaturization?
- Are Topical DHT Blockers as Effective as Oral Finasteride?
