@MaxVerstappen My understanding is that DHT standalone helps with hair growth, but it also changes the skull shape to be more masculine (think someone with an elevated, pointy top skull bone) and also increases the pressure exerted on the skull itself. fibrosis, probably from pufa, is what makes the scalp look tight and rigid and the head adapts to be more egg-like because of this. The DHT appears to be a red herring in the matter.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4174066/ is interesting:
"According to the theory, pressure on the hair follicles created by the weight of the scalp is the cause of AGA. Total weight of the skin, subcutaneous connective tissue, and galea are operative. With sandwiched fat tissue and fibrous connections between the skin and galea, all of these components of the scalp form a combined structure that sits on the cranial bones much like a separate structure movable on the cranial bones due to the intervening loose areolar tissue. Hair follicles are compressed by the skin against the calvarial bones. This theory is uniquely capable of explaining all related phenomena and paradoxes."
and
"DHT increases to help the hair follicle forge ahead deeper to reach its normal terminal follicle size in the face of increased pressure due to decrease in cushioning tissues. As long as the pressure on the follicle is adequately buffered, a base androgen level is enough and required for healthy hair growth. [...]"
"Increased DHT promotes hair growth probably mainly by stimulating mitosis in the early anagen follicle. However, increased growth pressure due to advanced mitosis cannot overcome the compressing pressure on the hair follicle but speeds up and shortens the anagen phase."
But our DHT levels decrease as we age. I think DHT only becomes an issue in the presence of PUFA.
I've heard Haidut said his fren fucked off to the mountains in asia at a very high elevation, and the higher CO2/altitude made him fully regrow his hair, starting from being completely bald. I've also heard Vitamin E being really good at capturing NO radicals and helping with regrowth, so if you're a guy that jacks off a lot, it's probably good as well. Personally for me, Progesterone, Aspirin, Vitamin B1 and Carboxytherapy on the scalp have been really good and keeping my hair in tact. I don't think even Ray believed you could go back to a juvenile NW1 with a good diet, because you've already adapted to and been weathered by PUFA.
The only thing I haven't tried, but would like to try is an experimental chemical that blocks PGD2 synthesis, so that you can have a higher PGE2 ratio to PGD2. "Twink" death happening seemingly because pretty boys are lower in PGE2, and as PGD2 increases they hit the wall and start balding abruptly.
