Q: Hi. I am 52 years old and wish to know if Propecia will work for 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. Occasionally we see patients in their 50s re-grow some hair with Propecia, but this is the exception rather than the rule.
