Are these miniaturized hairs??? Had PRP and started noticing thin new hairs. (Photo)

Prp will not increase hair fall. Prp is effective, but I have a very specific protocol, every 3-4 weeks for 6 months with prp therapy.  I also add in progesterone to speed the healing process.  After that the injections are tailored down.  You should also be on viviscal and other growth promoting ingredients. See an expert for a formal evaluation. Best, Dr. Emer

In my  opinion, the fact that your hair did get thicker from PRP treatments implies it probably was working. The new hair loss needs to be evaluated by your hair loss expert. I would suggest two biopsies and dermoscopy.. One biopsy from the top of your head and one from the posterior scalp. Hair biopsies need to be reviewed by a pathologist with hair experience. The specimens need to be sent for specialized processing. You can then work on a treatment plan with your hair loss expert based upon a firm diagnosis.

PrP can certainly trigger shedding in some patients. However the key thing to determine here is whether you have any component of androgenetic alopecia. I would need to see your scalp up close to determine that. That would be a common cause of short and long hairs of all different calibers. Your question is a good one - it’s essential to figure out if you have miniaturized hairs. This is best done by looking at the scalp rather than a few shed hairs.
