If you feel your head hair, it typically feels a lot softer and is easier to manage (comb, brush, fix) than a lot of other hair on your body - specifically I'm thinking about beard hair and pubic hair, which typically are a lot coarser than the hair on your head.

Why are these hairs thicker?

What causes them to grow differently than the hair on our head?

  • I have previously looked at that post @WYSIWYG, but I don't understand what makes the hair coarse on the body but fine on the head. – SolarLunix Jun 26 '15 at 18:17
  • Is it so?? I don't think that is true. – WYSIWYG Jun 26 '15 at 18:19
  • Well, pull out a piece of hair from your head, and pull out a pubic or beard hair and compare them, the beard and pubic hair are thicker. Also, if you look at hair closely under a microscope, scientists can tell if it is a "head hair" or a "body hair" @WYSIWYG – SolarLunix Jun 26 '15 at 18:21
  • Yes, of course body hair is different from head hair based on texture and thickness but I just said that the former may not be necessarily "coarser". It also varies from person to person. – WYSIWYG Jun 26 '15 at 18:35
  • What kind of answer are you looking for? Hair coverings are affected by follicle structure,and eyelashes and eyebrows and so on are also different. An evolutionary reason why these hairs would be different is one thing, and a complete description of all the weird follicles on your body is another. – Resonating Jun 26 '15 at 20:45
  • A little of both, but more the description of the follicle. Although why it got there in evolution would be interesting to know, too. @Resonating – SolarLunix Jun 26 '15 at 20:49
