Does PRP work for traction alopecia

I started to lose an unusual amount of hair about a year and a half ago.  I realized that it was likely due to simultaneously hardcore intermittent fasting (Telogen Effluvium) and traction alopecia caused by a regretful man bun.  Most of my hair is back now, and I’m not balding, but I lost density behind my hairline, and it shows sometimes, especially under overhead light.  Does PRP save some follicles and regain some density? 

By its nature, traction alopecia is usually an irreversible type of balding. I doubt that PRP will bring back those hairs. If it is extensive, then hair transplants work nicely. The telogen effluvium, on the other hand, is a temporary process and will reverse on its own. After re-reading your post a second time, I question if you ever had traction alopecia.
