Periodic Shedding from Finasteride?

i have been taking proscar for probably 7 or 8 years. a few years ago i had a pretty bad shed. freaked me out. however the hair did come back. again, i am having another shed and i\’m pretty stressed about it. is it normal to have sheds periodically even while on proscar?

It is important to realize the the genetic hair loss has its own course, independent of the effects of the drug. What you think is shedding from finasteride, is probably more genetic hair loss. Hair loss goes in waves and cycles of loss (shedding) most likely be due to your genetics, not the finasteride. You should discuss this with your prescribing doctor.
