Hmm I think your theory is a possibilty. It is a great mystery. I mean honestly at the end of the day, no one really knows how finasteride or minoxidil works and there is no long term studies on its effects. In essence we are the guinea pigs. But I personally have not had "hair thickening" as a result of the big 3. Ive had alot of gereral thinning (particularily on the sides of my head above my ears, its almost bald there!) YET my crown has definately filled in and maintained. My mid scalp and donor region is thicker than ever! And my hairline is holding. So im not complaining, because with hair thickening products my hair can look pretty good at times. So overall my experience on the BIG 3 is positive, not negative, but the mechinisms of how this stuff works is bizzare, it definately has some kind of overall thinning effect. Its a total roller coaster. Ive had some incredible lows, where i just thought it was all over and I thought of abandoning my treatments, but i stuck with it and suddenly turned the corner Whats your experience Doctorhouse?
