Are my scalp biopsy results conclusive of AGA? Should I ask for a transverse procedure to differentiate b/w AGA and TE recovery?

To differentiate between TE and AGA it's helpful to do two or three biopsies. These biopsies should be horizontally sectioned at three levels. Anagen/ telogen ratios as well as telogen /vellus hair ratios are helpful. I believe it's important to have your biopsy sent to a dermatopathologist who has experience with hair disorders.PRP hair MD.com

I suggest seeing a hair loss expert now to go over your condition, test results and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

No your biopsy does not prove AGA but if you are male and have hair loss, this biopsy result would suggest AGA. Yes, horizontal sections are superior for early AGA diagnosis.
