Stopped Propecia, Saw Catch Up Hair Loss

Dear doc,

I am a 22 year old male with thinning hair and a family history of baldness. Last summer I started taking propecia, but was too lazy to renew my perscription after three months. Since then I seem to have experienced the “catch up” hairloss I hear so much about and now, five months later, Im thinking of going back on it and staying for the long haul.

My question is though, should I expect any diminished results from restarting the treatment? Does propecia somehow lose its efficacy if you stop and restart it? Is it worth going back on?

Thank you for your time.

I hear about catch up hair loss over and over again. So many men start and then stop Propecia and experience hair loss upon stopping the drug, which just shows that it was working. Just go back on it and stay on it this time. It will not lose its efficacy, but you may be more ‘down the road’ on the balding process for stopping it.
