A recent study shows that the use of hair PRP as a therapeutic tool helps promote hair growth.  The capillary density being increased by 165 hairs per square centimeter after 12 weeks. Thanks in particular to the action of fibroblasts and beta catenin.

The benefits of platelet-rich plasma

PRP is a product of its own organism, so it is 100% biocompatible. There is no risk of allergy or rejection. In order to obtain platelet-rich plasma, the blood is taken from the patient. The blood is then centrifuged to separate the different blood components and recover the PRP.

The platelet-rich plasma when used in hair care is injected directly into the scalp to stimulate regrowth. PRP is also used for the preservation of grafts during follicular transplantation. Thus, after the removal of the hair follicles, they are kept in a bath of PRP awaiting their transplantation in the cleared areas. This technique improves survival. It strengthens capillary density and stimulates the growth of follicular units during a micro hair transplant.
