Are the photos I provided characteristic of Telogen effluvium/recovery? My "recovery" seems slow. (photos)

Last November (18 months ago) I experienced drastic shedding occur on my scalp at the vertex. My hairline remained unaffected. My scalp remained red/tender in the shedding zone. I saw a dermatologist last October (7 months ago). She said the hair would grow back on its own. More Context: I started a stressful job a couple of months prior to shedding began and experienced a two-week flu in the weeks prior to the shedding. I left the job last April following a surgery (13 months ago).
