How can I find a dermatologist who knows a little more about hair loss?

[LosingHairIsNotFair]

My dermatologist is pretty clueless when it comes to finasteride, its side effects, and male pattern hair loss in general. I'm thinking of going to someone else. I would also like to get a scalp biopsy, because I've got some weird thinning going on on the sides and back of my head (I'm just hoping to God I don't have DUPA and it's Telogen Effluvium or something). Can any dermatologist give a scalp biopsy? She didn't even look at the sides of my head when she first prescribed it to me, she just looked at the vertex. If I were a doctor I would look all over to rule out any weird ****.
Would it be better to find a hair transplant surgeon to give me a biopsy?

I don't know anything about scalp biopsies.

Do some googling and look for dermatologists in your area who specialize in hair loss; there must be some. Call hospitals and ask if they have any dermatologists who list hair loss as a specialty.
