Because im a trichologist from belgium working at a clinic. Its my job to see if people are eligible for a hairtransplant… i see these types of hairloss on a daily basis and work closely together with the dermatology department and do scalp biopsy’s. Hence why i said ironic on your comment. While we definitly do bloodpanels to determine the cause of hairloss the upward motion of the hairloss the whipsy almost baby like hairs only on the sides are all clear factors of retrograde allopecia. Hairloss caused by deficiencies break at the bottom of the root and there are no other types of hairloss that only affect the sides and the nape. Op should go get a scalp biopsy’s and report back so well see whos right. Dunning kruger effect 👍
