My Doctor Told Me to Take Finasteride Only 3 Times a Week

After having a hair transplant this past September, my doctor prescribed me Proscar. He directed me to take 1/4 pill 3 days a week (Mondays, Wednesdays, and Fridays). My question is, will this dosage and frequency be enough to keep the hair I have and possibly grow new hair? I’m confused as to why my doctor did not direct me to take 1/4 pill EVERY day. Any comments on this are much appreciated.

I couldn’t tell you why your doctor directed your dosing as he did, as it makes no sense to me and he seems to be ignorant on the mechanism and pharmacology of finasteride. I can see valid reasons for taking a smaller dose in some cases, but I don’t see the point in taking the medication every other day (rather than daily). With a half life for the drug of 4-5 hours, there may be nothing to protect the hair follicle between doses.
