“Hairaches” (sans ponytail, at the follicle) - what’s going on?

Everyone is familiar with the “hair in a ponytail/bun all day ache” and that “good pain”/relief you feel when rubbing/massaging your scalp afterwards. I’m talking about that same feeling, except it just kind of happens on its own? Hair down all day.

I’ve noticed it in certain circumstances: - if I leave my hair natural, it will happen when my hair gets oilier around 4-5 days after my last wash - if I blow dry/style it after washing it, I’ll feel it at my crown by the end of the day or the next - It will happen whether or not I use any products, but it’s more likely to happen quicker if I use a heavy product or a gritty dry shampoo.

My hair is medium texture, low-medium density; wavy/curly except around the top canopy/crown area. It tends to get heavier/oilier faster if I heat style vs air drying. A lot of my density is in the back from my crown down to the nape of my neck (I have a pretty aggressive widows peak so not a lot of density at the front) - the “ache” feeling is usually towards the back and the perimeter around the nape.

My best guess whenever I think about this is that I just have a head full of cowlicks I can’t see and my hair doesn’t like laying in a way it doesn’t get to choose / the weight pulls it down? I’ve brought it up with my stylist (mostly to ask if she noticed anything on my scalp I can’t see) but she said there was nothing notable. It’s also kind of a hard thing to ask google lol.

Anyway, wondering if anyone has some general knowledge/ideas about this? Thanks for your time :)
