Accuracy of Scalp Biopsy for Hair Loss?

How accurate are scalp biopsies in diagnosing hair loss?

Scalp biopsies are not accurate for the diagnosis of hair loss. The best way to diagnose hair loss in men, is with miniaturization mapping and pattern determination for the hair loss.

You can also have the gene detected (see HairDX), but that will only tell you have you are carrying the gene… not if you have active hair loss.
