I'm sorry, but I also can't tell from your description what you are referring to. You seem to be describing actual ridges in your
headHead and face reconstruction
Head injury
Head lice
Indications of head injury
Radial head injury. They are probably
normalNormal saline flush, only you didn't notice them until you cut your hair short. But that's all I can guess at. I think that if the two dermatologists you saw didn't know, then it's probably not anything serious. If you're still worried, you should get another opinion.
Best.
