good hairloss Doctor in philly area?

[returnoftheshedi]

Does anyone know someone? I've been losing my hair for over 7 years and want to give a doctor one last shot. I had been to several derms who couldnt offer me any advice (i have diffuse thinning) and before i give up and shave my head bald i'd like to talk to someone who knows a little about hairloss.

thanks!!!
