What’s the First Sign That Finasteride Is Losing Its Effectiveness?

I’m almost 26 years old and been using Fin 1.25mg for exactly 4 years for early hair loss. Since starting fin my hair loss ceased completely, I still look the same like 4 years ago! For the past few years I also saw way less hair shedding.

For the past 2 months I see a much bigger increase in hair shedding including weak hairs. My hair length is always the same (medium long) and I been using the same hair products gel & mousse all the time. When fin loses effects is increased hair shedding the first sign? So far my hair still looks the same but I’m definitely very worried.

I have said this over and over here on BaldingBlog: There is no way to completely stop hair loss (your genetics win out in the end).

Finasteride (Propecia) will help, but everyone is different in how they respond and how their genetic predisposition will work out. There is no sign that indicates finasteride is not working, but it is more about how your genetics is winning. It might just be semantics, but I want to be sure everyone is clear. If you see the loss start up again, finasteride is still working, but your genetics are winning out. It doesn’t just stop working.

I can’t explain your recent increase in hair loss, but if you’re concerned you should pay a visit to your prescribing doctor for a follow-up exam. If your doctor made bulk measurements before you started the medication, he could tell if your hair loss has picked up again. Get some good measurements of your hair loss so that in the future, you can tell what is really going on.
