The most common form of hair loss in men is termed androgenic alopecia, affecting 30-40% of men by the age of 50 (1). The pattern typically affects the temples, top of the head, and the frontal hairline. While this is considered a minor condition, hair loss can impact self-image and cause anxiety and depression in some men. Heredity plays a huge role in male pattern hair loss.
Hair growth occurs in a cycle and broken into 3 different phases: growth, regression, and resting. These phases are regulated by internal and external factors throughout ones life. Baldness occurs when the resting phase of the hair follicle gets longer and the growth phase of the hair follicle gets shorter. Before a growth phase is initiated, stem cells surrounding the hair follicle become active. When hair follicle cells regress, or return to their less developed state, cells surrounding the follicle are seen dying. And during the resting phase, hair follicle cells are basically in a state of inactivity (2).
Platelet-rich plasma has shown remarkable beneficial effects to treating hair loss in men without any major adverse reactions. The patient’s blood is used to extract their own platelets and then the platelets are injected into the area of baldness. The basic idea behind PRP injections is to deliver a high concentration of growth factors to the scalp, with the hope of stimulating hair growth and improving the function of the hair follicle (3). Under microscopic evaluation, the hair follicles increase in numbers, more blood flows to the follicle, and there is increased cellular activity (4).
In a review of literature looking at twelve studies conducted from 2011-2017, and using a total of 295 subjects, most of the studies reviewed showed effectiveness of PRP in increasing hair density and diameter (5). Another study, using 20 people, revealed a mean increase of 33.6 hairs in the target area and a mean increase in total hair density of 45.9 hairs per cm2,5. Using PRP therapy for male pattern baldness has been proven to be effective. Many products like Rogaine must be used continually throughout one’s life, and when treatment stops, the hair falls out again. With just a few treatments of PRP, you’ll see more lasting results without any major side effects.
