Follicular Unit Extraction (FUE) The hair replacement field changed dramatically with the development of FUE. With this procedure, individual follicles are harvested from the back of the head – the area in which hair tends to remain the thickest and healthiest even when losing hair elsewhere. The follicles that are extracted are then individually transplanted into the area of the head targeted for hair replacement. A single follicle may contain a number of individual hairs attached to it.
The procedure involves a careful diagnosis of the current need for hair replacement using the Savin scale (see Figure below). The areas in need of transplant are identified along with the number of follicles that will be needed to obtained the desired coverage. A technician then harvests the areas from the safe area (immune from DHT) in the back of the head and transplants them into the target area on the crown, top of the head or eyebrows.
While there are a number of different FUE devices (e.g. NetGraft, Artus, SmartGraft), Capily Institute recommends the SmartGraft device and procedure as it produces follicles with higher viability for the transplant. Why is this the case? The SmartGraft device allows all follicles to be collected, counted, stored in a sterile temperature-controlled and hydrated environment. As each follicle is individually extracted it is sent through a tube where it is cleaned and kept in a climate-controlled environment to maintain hydration and viability while waiting to be transplanted. As it can take a few hours for the individual follicles to be harvested, depending on the extensiveness of the transplant procedure, other devices may allow the follicles to dry out, reducing their viability.
After the desired amount of hair has been harvested, the transplant recipient area is then locally anesthetized. This is the area that you and the Hair Transplant Expert Team had marked together at the very beginning. One hair follicle at a time is transplanted using the device. It first creates holes for the donor follicles. A scalpel isn’t needed for this step. The hairs are then inserted into these holes. The system ensures the hairs will be placed at the right depth and the correct natural angle. Your transplantation procedure will take around five to six hours. You will go home thereafter and may return to normal social life after 2 days.
Platelet Rich Plasma Injections (PRP) Our blood contains two different elements – red blood cells and plasma. The plasma contains white blood cells and platelets. Platelets are rich in growth factors. PRP has been used for decades to increase healing injured tendons, ligaments and muscles, for example in joints with arthritis and more recently to help increase collagen production in facial skin rejuvenation. PRP is a three-step process by which a small amount of a patient’s blood is drawn (Step 1) and put in a centrifuge. Spinning the blood allows it to be separated, obtaining the platelet rich plasma (PRP) (Step2). The PRP is then placed in a syringe and injected into the area of thinning hair (Step 3) at the level of the hair follicle. Combining the PRP with thrombin or calcium chloride results in the production of growth factors (cytokines). By performing multiple injections about one half an inch apart in the target area, the PRP stimulates growth of existing hair follicles and generation of new growth. Each hair follicle can have multiple hairs growing from it. The PRP increases blood supply to the hair follicle and increases the thickness of the hair shaft as a result.
The standard protocol is for this less than one-hour procedure to be performed once a month for three months initially and then once every four to six months to continue the growth cycle. Information from realself shows that 73% of patients believe that it is worth it. Research from India indicates that average increase in hair growth experienced was approximately 30%.
