Hi, I'm 25 years old and am loosing hair rapidly, specialy towards the front of my head. I've been taking a lot of vitamins D,B,A,Iron, a good multiple, but I'm still loosing hair. I want to have tests done and get a definet dianoses. I want to have my hormones checked out, and also to get a biopsy done on my scalp, to rule out any kind of fungus. Do I need to contact a hair specialist or can I go to any doctor for the scalp biopsy?
