Will prp keep my hair?

[Ziggyz123]

This has probably been talked about before, but will prp injections keep my hair and thicken it? I visited a doctor in nj who was/is doing them and he said as long as you keep doing them it will keep the hair you have and thicken minaturized hairs as well as existing hair. I didn't do it with him because he was really pushing it and he also didn't do prp in conjunction with a cell or anything like that.
