I hope this qualifies as injury and rehab, if not i gues it can be moved to another topic, but hair loss is sort of an injury and trying to get it back could be considered rehab, so here goes...
I've read articles in the past about the causes of male pattern baldness and how one can attempt to reverse it. DHT is the culprit in most scientific literature, so people use finisteride to reduce 5-alpha reductase, and thus reduce their DHT- the only problem with that is you can experience sexual side-effects that can be permanent. I've also read literature that blames inflammation for being the culprit, and that anti-inflammatory drugs can be used to combat male pattern baldness and receding hairlines. finally, and more interesting to me is the fact that estradiol or some isomer of it can be to blame. I haven't seen anything written about this lately. Has that theory been debunked?
Being a 40 year-old, having used P.E.D.s off and on for 20 years, and having both a receding hairline and a small bald spot on the vertex of my scalp, I'm very interested in keeping what I've got. I've used my own concoctions to help reverse it. I tried cayenne-infused olive oil topically, I've put comfrey root powder and ground-up zinc in my hair gel, as well as topical curcuminoids and ginger root among other things.
In conclusion, I feel it's likely that DHT and estradiol can both over-activate a receptor, in turn causing sebaceous glands to become inflamed, swell, and choke off the nerves and blood supply to a hair follicle causing it's death. A combination of an anti-aromatase, a DHT blocker, and a topical anti-inflammatory could work. Any stories others may have regarding concoctions they have made and used would be interesting to me.
