On Accutane 5 years ago and experienced hair loss the last month of medication. The thinning has not stopped. Advice? (photos)

I have gone to three dermatologists and a hair loss facility and no one can figure out why the hair loss is still going on. I was diagnosed with telegen effluvium originally and was told that it would last no longer than 6 months. 5 years later, I am very frustrated and confused as to why it is still happening. I have tried rogaine, spironolactone, nutrafol, laser caps, and PRP. Does anyone have an idea as to why this is still occurring? (For reference, I was 16 when I went on it and 21 now).
