Everyone has whorls (at least two - one in the back upper part of the head, one at the front - but sometimes more than two; for instance, the center back whorl but two whorls in the front rather than just one).
Look at any new baby's head and you'll see them.
They are also way more visible on shorter hair because the hair biologically intends to grow long; therefore the "waved" pattern (deep or subtle) started within the whorl is meant to grow around and away from the center and then down the head. Cut short rather than going to its own natural length, hair will be "stunted" in position - in the act, in other words, of waving toward the back, toward the side, etc. It's MEANT to go upward and then curve down around the head. But we cut it so that we're left with the beginning couple of inches or less of hair, where the growth is in that up part before curving around and down. Shorter hair sticking up is a pretty common thing. So is shorter hair seeming to stick up in various directions. (That's why hair gel is so popular!)
The main reason for a cowlick or more than one cowlick (whorl) in the front is that human hair grows long when devices are not used to stop that (i.e. scissors, razors), and if there were nothing flicking the hair back or to the side, the long hair would literally fall over the face and stay there.
I have collarbone-length hair and am growing it very long. (Sometimes I get sick of it and cut it; right now I'm in a growing-back period.) It is very fine and "slippery" feeling and straight. I love the way it feels, I sometimes obsessively rake my fingers through it again and again. But as far as looks go, it's definitely nothing to write home about, either for good or for ill. I've been coloring it dark with herbs but a few months ago started growing that out too. My natural color is that not-blonde, not-brown, not-uncommon color. I don't really style it but I keep it clean and brushed and shiny.
But my sister, who is no-way, no-how on the spectrum - in fact, she's a social butterfly, never had any delays or comorbids, gets along with NTs, thinks like NTs, IS NT - has hair that's very, very like mine, the single exception being the color. Hers is a shade darker than mine.
My oldest son, who is probably an Aspie, has normal short dude hair that sticks up until it's about 1.5" long (I think). My middle son is Kanner autistic (moderate) and his hair is VERY thick, nothing at all like mine, and sticks up until probably a little over 2", at which time it starts lying down again. My middle son with ADHD and some autistic-like tendencies but no ASD DX has hair exactly like mine, and I mean absolutely, positively exactly like mine, it's eerie, it's like I transplanted my hair onto his head. The color, texture, patterns and thickness are all exact.
