Platelet-rich plasma (PRP) injections used with stem cell therapy as an add-on treatment have been used as a recent, non-invasive alternative to traditional hair plant procedures.

The way that PRP with stem cell therapy works for hair loss in men and women is that it uses PRP and stem cells from a separate part of the patient's body to restore dead hair follicles in their scalp.

Medical researchers believe that PRP with stem cell therapy works for hair loss because of the proteins inside the platelet-rich plasma and the growth factor of stem cells. So, by injecting PRP and stem cells into the scalp, they have the potential to regenerate the hair follicles and promote hair growth.

Also, the PRP and stem cells would be extracted from the patient's body, meaning there is little to no risk of the cells being rejected in the scalp.
