Random Riddle: Uncombable Hair

I am not a human, nor am I an animal.
I have eyes, but cannot see,
and I have hair that you cannot comb.
My brown skin has several layers, but this seems a paradox,
because one is smooth, and the other is hard.
My skin protects my soft white flesh;
and within my flesh is my opaque blood.
