headHead and face reconstruction
Head injury
Head lice
Indications of head injury
Radial head injury. They are probably normal, only you didn't notice them until you
cutCuts and puncture wounds your
hairHair loss
Hair transplant
Male pattern baldness 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.
