There is some confusion here about the diagnosis of hair loss. it’s important to understand we don’t diagnose AGA by looking solely behind the ears like this. Of course, one needs to know what’s happening on all the scalp but this is not how one renders a diagnosis of hair loss. Diagnoses of AGA starts by examining the front, crown and comparing trichoscopy and clinical findings to the sides and back. Then one examines eyebrows and lashes and body hair and nails. As far as these pictures go, it does not appear that loss of ostia is a major mechanism of the loss. There is a reduction in density and caliber of hair together with some inflammatory changes. You will want to see an experienced practitioner for proper evaluation. This here is not how one confidently renders a diagnosis. The diagnosis of hair loss requires one to know absolutely everything about the patient and his or her story and to examine every square inch of the scalp. There are really no substitutes. In this case, androgenetic alopecia, telogen effluvium and seborrheic dermatitis need to be properly evaluated and other issues like psoriasis, other forms of dermatitis and traction alopecia need to be given consideration. Please see an expert.
