How can PRP prevent hair loss when it cannot stop DHT from attacking follicles?

In my opinion, this is an excellent question. PRP does not counteract DHT directly. The various growth factors in PRP work to increase the diameter of the hair, increase the growth cycle , regrow dormant hair and speed hair growth. It works to counter the effects of DHT. However, as you can see, if you use a DHT blocker such as finasteride or dutasteride the effect of PRP increases. It does not have an androgenic opposition. How this helps. Good luck. 

PRP can help regrow hair and thicken it. I suggest you see an expert for an evaluation of the cause of your hair loss.  Best, Dr. Emer.
