How Is it Possible That Genes Will Triumph Over Propecia?

I know it requires DHT, genes and age for MPB to start. Propecia reduces DHT a major cause of MPB. Surely it doesn’t lower all DHT but enough to keep hair years and years for most men. You always say that genes will eventually win over Propecia. How is that possible? Propecia supresses DHT removing what’s needed for MPB genes to work! Since that’s the case shouldn’t Propecia forever? Or is it because of the remaining DHT that Propecia doesn’t supress works slowly with genetics until one day makes MPB progress despite being on Propecia? So in that case how come they haven’t found a drug for 100% DHT suppression yet? That would do the trick!

Finasteride (Propecia) blocks about 70% of serum DHT. By comparison, dutasteride (Avodart) blocks about 90% of serum DHT…. but nothing is 100%. Also, we know that it takes more than just blocking DHT to stop hair loss. Our adrenal glands do produce androgens as well as the testicles and can contribute to hair loss. This may be a hard concept to some, so here’s a simplified attempt at answering your question with an example. You can take all the anti-aging pills you want, but you will still age and die one day. Final score — Genes 1, Pills 0.
