Hair

A few days ago, we had the article about a correlation between hairiness and the speed of wound healing. Well, this one, from PopSci, talks about the hair part.

    How is head hair different from body hair?  
There's a reason you can't grow your armpit hair to your belly button.

You know if we could, someone would turn it into a fashion statement.

Hair can be curly, straight, thick, thin, brown, black, blonde, or auburn. It can be long or short, frizzy or lush.

The musical   did it better.

We have two types of hair, says dermatologist Elizabeth Houshmand. Vellus hairs, or “peach fuzz,” cover virtually our entire body but aren’t easy to see. Our head, chest, armpit, and pubic hair consists of terminal hairs. These are thicker and darker.

The author forgot nose and ear hair in the latter category.

But not all terminal hairs are alike. For example, the hair on our head can grow far longer than that on the rest of our body. To understand why, we have to dive deep into our skin.

Phrases like that really get under my skin.

The article goes into a brief bit of scientific detail, then:

But bald men can still retain thick body hair. Radusky, who has worked on clinical trials for hair loss conditions, explains this is due to the conversion of testosterone as we get older. An enzyme called 5-alpha reductase changes the hormone into dihydrotestosterone.

And so we see how another problem is caused by testosterone.

The article's pretty short (unlike my hair) and, I would hope, uncontroversial, so I don't have anything else to say. I'm sure people have something to say to me, though, like "Get a haircut   and get a real job."

To which I can only reply: No.
