There are different forms of areata - universalis, totalis, circumscript, reticulated, ophiasis and diffuse. Diffuse is defined as: " ... a form of incomplete hair loss affecting the whole scalp without distinct patches. This type can be difficult to diagnose and may require a biopsy. To help in the diagnosis of any type of alopecia areata, the dermatologist always looks for exclamation point hairs - broken off short hair that taper (get narrower) toward the scalp." I was diagnosed with this by one doctor (without biopsy), but I have my doubts. Treatment is topical steriods and Rogaine.
