How Can MPB Catch Up If You Take Dutasteride, Which Blocks Up to 90% of DHT?

Doc,

You have stated in previous answers that no matter what treatment a male is on, Male pattern baldness will eventually catch up. I do not see how this is possible since drugs such as Dutasteride can block up to 90% DHT when taken on 0.5mg form. Lets say it is approved in five years time for MPB by the FDA and taken along with minoxidil twice a day, how would MPB be able to catch up since the main factor; DHT is blocked?

Are then any studies that actually back up your opinion/theory?

If this is the case then surely every male suffereing from MPB including myself is throwing their money down the drain?

I suspect MPB is not singularly dependent on the concentration of DHT alone. Small amounts of DHT (the 10-20% that still is produced, even with taking dutasteride) can still trigger hair loss. Case in point, there are a few of my patients who have chosen to take dutasteride, but they still lose hair. I do not believe taking medications such as finasteride or dutasteride is “throwing their money down the drain,” because I have seen clear evidence on many of my patients that it does work! All medications have limitations — yes, including dutasteride and finasteride. For example, you can take the most potent anti-oxidant anti-aging medication, but you will still grow old and look your age.
