Recommendations for a great doctor in Houston?

[razzer]

I've been experiencing hair loss that seems to stem from an antibiotic. My story is outlined here - http://www.baldtruthtalk.com/showthread.php?t=13824

After visiting with a doctor who acknowledged antibiotics can (although rarely) cause hair loss he recommended I see a specialist but didn't endorse anyone specifically.

Can anyone here recommend a good doctor or dermatologist in Houston with a specialization in hair loss?

At this stage I'm looking for an investigative, humble doctor that can diagnose my condition, not someone who will simply eyeball my scalp and throw prescriptions at the problem or try and push a procedure.

Before I treat this problem I would like to find out what's causing it, if it is already improving, and/or how long it will take to improve if it will improve...

Thanks in advance to anyone who can help. It's tough man.
