How Platelet-Rich Plasma Can Assist with Androgenetic Alopecia?

​

The word alopecia is derived from the Greek term for fox, "alōpēx," which refers to a fox that has lost its fur due to mange (MAYNJ). In simple terms, it signifies hair loss, and when this occurs as a result of elevated male hormones (androgens) and genetic factors, it is referred to as Androgenetic Alopecia (AA).

​

Current medical treatments for AA are often unsatisfactory due to patient noncompliance and the side effects associated with medications. A promising approach in regenerative medicine involves utilizing the patient's own blood to produce Platelet-Rich Plasma (PRP), which has shown effectiveness in promoting hair regrowth.

​

How does PRP function?

​

Following the extraction of the patient’s blood, it is collected in a specialized tube designed to prevent clotting. A centrifuge is then utilized to separate the components of whole blood according to their specific gravity. Consequently, the platelets rise to the top of the tube, while the red blood cells settle at the bottom. By aspirating the platelets from the upper section of the tube, we obtain a platelet concentration that is 3-5 times greater than that found in normal blood, hence the term Platelet-Rich Plasma.

When administered at a precise location and depth within the scalp (subdermal depo bolus injection) by a qualified cosmetic practitioner, the contents of each platelet can activate existing hair follicles, promote the formation of new hair follicles, and enhance the size of hair shafts.

What are the recommended intervals for treatment?

​

The initial three monthly sessions should be succeeded by a fourth session after six months, followed by maintenance treatment every 12 to 18 months.
