“PRP was started in the States back maybe you know 15 years ago PRP into the scalp at least in our clinic we were using it as a wound healing treatment in conjunction with hair transplantation and we because I'm remember I'm a born and raised general surgeon we know that anytime you want to cut the skin you want to heal it and so hey by the way low-level laser therapy does that too but PRP was one of the first indications was for wound healing for chronic ulcers and and to accelerate healing in diabetics and so forth”
