Does anyone have thick hair strips where their head creases?

[Piccolo]

I have like... 2 small trenches in my skull on each side of my crown, I can feel them all the time and I sleep on my sides so they're always having pressure put on them and being formed more. I don't know if that's just the shape of a person's skull or what. The problem is my hair grows out MUCH thicker from these strips... I'm not sure why, but I would guess the minoxidil or the finasteride helps those areas more than the others because they are closer to the blood than the rest of my dome. It really sucks though because the contrast is so large that even when I clip them carefully with scissors as low as I can get they are still totally visible. It's getting worse looking and it's ruining what was an ok looking buzz cut.

Anyone else have this problem?

I dont have exactly what you are talking about but I noticed I have a "ridge" across the center top of my head. Sort of like a long indent, and its kind of the opposite, hair is thinner along this ridge (might just look this way) but it makes it look like I have thin strip across the top of my head.
