I have been bald since I was 30. I am now 73. There was no hair to speak of (you call it a Class 6 Pattern according to your book). I finished my chemotherapy for prostate cancer and my hair grew back. Any comments?
The chemotherapy must have taken away your ability to make testosterone and it’s byproduct, DHT. That would account for a regrowth of your hair (as if your testicles were removed, in the chemical sense). It would be unusual to grow your hair back completely if you have been that bald for so many years (I’m assuming it has been at least 20 years), unless there was still hair present that was heavily suppressed by the testosterone you had circulating around. I would love to see before and after photos of your hair growth.
