Do animals sweat? Most don’t, but some do. Dogs sweat mainly between the pads on the bottom of their paws. One notable exception is the American hairless terrier, which has sweat glands all over its body, illustrating the fact that fur tends to inhibit sweating because if the sweat can’t evaporate it doesn’t help in the cooling process.
The top of a bald scalp sweats more than the top of a hairy scalp. Perhaps where lymphatic drainage is greatest on the human body, more hair grows. I remember that in my early 20's I grew more chest hair after I started practicing the bench press at the gym.
Maybe a bench press for the scalp would be helpful.
With respect to the Hamilton study, I recall reading that 20 year old castrates injected with testosterone started going bald at the normal rate while 60 year old castrates injected with testosterone progressed to almost completely bald in a few months. Genetics could be strongly implicated in male pattern baldness.
Can long lost hair "regrow"? ...maybe in some rare cases...
This 73-year-old white male has been bald since the age of 28. He developed nonA-nonB-induced liver cirrhosis and had been treated with spironolactone for the last 6 years. For the last 3 months, his hair had started to regrow over the scalp. This might be related to the antiandrogenic effect of spironolactone.
Spironolactone is a diuretic...
