I Switched from 1/4 Proscar to Generic and My Hair Loss is Worse

First of all thank you for what you do with this site it is a tremendous resource. I am twenty and began to recede at the hairline about a year ago. I started taking one fourth of a proscar daily in April without a prescription and got a prescription for it in June after seeing a dermatologist. I have since been taking the generic version daily. The medication does not seem to be working as I have continued to lose much hair from my crown to the point where my scalp is visible in harsh lighting.

I have long hair but i have noticed in the last week that I am losing the very short (terminal?) hairs again after not noticing them for the past few months. Could this be due to the switch to the generic version? The proscar pills were individually sealed while the generic are together in a pill bottle could this air contact affect their potency? As it has been seven months and I have lost noticeably more hair should I discontinue the medication?

Thank you, my dermatologist is pretty clueless when it comes to hair loss, so I appreciate your knowledge.

Generic finasteride 5mg is the same drug as Propecia, which is just finasteride in 1mg strength, so there should be no difference in efficacy. I don’t think bottle vs individually sealed has any bearing on the potency.

Finasteride does not work that well for frontal hairline, so what you may be experiencing is just your normal course of hair loss that the drug cannot address. Harsh lighting will make the hair appear thinner. Do you have comparison photos to look at from before you started? You’ll need to discuss changes to your medication with your prescribing doctor.
