What is PRP?

Platelets are cells in blood that are responsible for clotting and the release of growth factors to help the healing process. Platelet rich plasma (PRP) is a concentrate of your own blood that contains high numbers of platelets which is 4-7 times the normal concentration of platelets in blood. It can injected into a certain area to exploit the platelets function and enhance wound healing and to help rejuvenate skin. Because it is a part of your own blood, it is free from transmissible diseases, and cannot cause hypersensitivity or allergic reactions.

What Does The Treatment Involve?

During the treatment, 10 – 20 mls of blood is extracted from the patient. This blood is placed in the centrifuge for 5 – 8 minutes. When centrifugation is complete your Plasma will be separated into three layers. The platelet rich plasma layer is extracted and injected into the deep dermis or fat layer of the skin. Platelets gradually increase collagen which can increase skin thickness and overall health of the skin. Three treatments one month apart is advisable followed by a maintenance of at least once a year preferably every six months. The process takes 45 minutes to an hour.

PRP for hair loss

How Does PRP Help With Thinning Hair?

PRP uses tiny injections of your own platelets and plasma isolated from a small sample of blood to ‘tell’ your body to repair whatever tissue you put it into, and rejuvenate it at a cellular level. When used for hair loss, it stops the hair from miniaturising (getting smaller and thinner), and helps to ‘wake up’ existing hair follicles, reversing hair thinning. If the hair follicle has already completely died then you won’t be able to stimulate it to grow hair, so PRP usually works best in people who have started noticing their hair thinning in the last 2-3 years.
