Splitting Hairs: Evaluating the Origin of Human Nakedness

Hair loss is humorously blamed on ancient selection preferences, with discussions on genetics and societal norms. Treatments like finasteride are mentioned as modern solutions.

Hair loss is influenced by genetics and sensitivity to hormones like DHT. Treatments like Minoxidil and finasteride are commonly used, and baldness persists as it doesn't affect reproductive success.

Male-pattern baldness might increase UVB exposure on the scalp, potentially affecting vitamin D and skeletal health. The hypothesis is debated, with some seeing it as a minor benefit in specific contexts.

Body hair is more resilient than scalp hair due to different gene expressions and DHT sensitivity. Treatments like minoxidil and finasteride are used for hair loss, but they have varying effects on body and scalp hair.

The conversation discusses the hypothesis that a lack of the enzyme 3-alpha hydroxysteroid dehydrogenase (3α-HSD) on the scalp may contribute to hair loss by allowing DHT to accumulate. Despite interest in this theory, no recent research has been conducted, and current treatments like finasteride and minoxidil remain the most supported options.

Hair regrowth treatments are effective in mice but not yet available for humans. The discussion humorously highlights frustration over this disparity and mentions a project to genetically modify elephants to resemble mammoths.
