Weird Eyebrow Hairs

It's no secret that your hair starts doing strange things as you get older. By way of example, here are three hairs that I plucked out of my eyebrows several months ago.*


The hair in the middle is entirely typical. Almost all of my eyebrow hair looks like that: straight, thin, flexible, and brown.

The hair on the RIGHT is the type I'm seeing more and more: white, coarse, and much longer than usual. These hairs are like vicious spikes and they really yank when I pull them out.

The hair on the LEFT, however, is the weird one. I see one of these every six months or so. It's globular, stunted, and irregularly coloured. Since it's so thick and chunky I see it immediately when it grows, and all I need to do is prod it to make it come out.

I understand the concept of grey hair -- and I suppose that's what's happening to the hair on the right -- but fat little glob-hairs? I don't get it. I'm wondering if anybody else gets hairs like these.

* I didn't save these hairs for a year and then put them online today; this is an old picture from my old camera, which had obvious problems focusing on little nearby objects.
