My scalp is very wrinkly, almost like a shar pei dog. What is this and how can I fix it?
This is called cutis verticis gyrata (CVG). The cause is unknown and there’s no known cure (though cosmetic surgery might be an option).
Basically, the condition is when a great deal of skin, far more than is needed to cover the skull, is generated by the body. I have seen a few mild cases of this condition and have written briefly about it a couple years ago. Look at Google for more examples.
