In the field of hair restoration and regenerative medicine, Platelet – Rich Plasma (PRP) has gained significant popularity. Not all PRP is the same; there are three main types, each with distinct characteristics, preparation methods, and potential applications. Understanding these types can help both patients and medical professionals make informed decisions about the most suitable PRP treatment for hair loss and other conditions.
Pure PRP
Preparation
Pure PRP, also known as leukocyte – poor PRP, is prepared with the primary goal of isolating a high concentration of platelets while minimizing the presence of leukocytes (white blood cells). The process begins with drawing a small amount of the patient’s blood, typically from a vein in the arm. The blood is then centrifuged at a carefully controlled speed and duration. The first centrifugation step separates the blood into its major components: red blood cells at the bottom, a buffy coat containing white blood cells and platelets in the middle, and plasma at the top. In the case of pure PRP, the plasma and a portion of the platelet – rich buffy coat are carefully collected, while minimizing the inclusion of white blood cells.
Composition and Mechanism of Action
Pure PRP is rich in platelets, which contain a variety of growth factors. Growth factors like Platelet – Derived Growth Factor (PDGF), Transforming Growth Factor – beta (TGF – β), Vascular Endothelial Growth Factor (VEGF), and Insulin – like Growth Factor – 1 (IGF – 1) play crucial roles. PDGF stimulates the growth and division of cells such as fibroblasts and dermal papilla cells, which are essential for hair follicle health. VEGF promotes angiogenesis, ensuring an adequate blood supply to the hair follicles. By delivering these growth factors directly to the scalp, pure PRP can stimulate hair follicle growth, prolong the anagen (growth) phase of the hair cycle, and increase hair follicle size.
Advantages and Limitations
One of the main advantages of pure PRP is its reduced inflammatory potential. Since it contains fewer leukocytes, there is a lower risk of an inflammatory reaction at the injection site. This can lead to less post – treatment discomfort for patients. However, some studies suggest that the absence of leukocytes may limit the immune – modulating and antibacterial properties that could potentially enhance the healing process.
Leukocyte – Rich PRP
Preparation
Leukocyte – rich PRP, as the name implies, contains a higher concentration of leukocytes along with platelets. The preparation process is similar to that of pure PRP, but the collection method is adjusted to include more of the buffy coat, which is rich in white blood cells. This results in a final product that has a significant amount of both platelets and leukocytes.
Composition and Mechanism of Action
In addition to the growth factors found in pure PRP, leukocyte – rich PRP contains various cytokines and immune – modulating proteins from the leukocytes. These components enhance the body’s natural immune response at the treatment site. Leukocytes can help fight off potential infections and reduce chronic inflammation in the scalp. The combined action of growth factors and immune – modulating substances can create a more favorable environment for hair follicle regeneration.
Advantages and Limitations
The presence of leukocytes in leukocyte – rich PRP provides enhanced antibacterial and anti – inflammatory properties. This can be particularly beneficial in cases where there is an underlying scalp infection or chronic inflammation contributing to hair loss. However, the higher concentration of leukocytes may also increase the risk of aLeukocyte – Rich PRP.

However, the higher concentration of leukocytes may also increase the risk of an inflammatory reaction at the injection site, leading to more discomfort for the patient.
Leukocyte – Depleted PRP
Preparation
Leukocyte – depleted PRP is a variation that aims to remove as many leukocytes as possible from the PRP preparation. Specialized centrifugation techniques and filtration methods are used to separate platelets from leukocytes more effectively. This results in a product that is highly concentrated in platelets but has a minimal amount of leukocytes.
Composition and Mechanism of Action
Similar to pure PRP, leukocyte – depleted PRP relies on the growth factors within platelets to promote hair follicle growth. By removing leukocytes, the risk of an unwanted inflammatory response is further reduced. The growth factors can stimulate follicular cell proliferation, improve blood circulation to the scalp, and enhance the overall health of the hair follicles.
Advantages and Limitations
The main advantage of leukocyte – depleted PRP is its low inflammatory potential, which can lead to a more comfortable treatment experience for patients. However, the extensive processing required to deplete leukocytes may also potentially reduce the overall viability of the platelets or some of the beneficial growth factors.
Conclusion
The three types of PRP—pure PRP, leukocyte – rich PRP, and leukocyte – depleted PRP—each offer unique benefits and considerations. The choice of which type to use depends on various factors, including the patient’s specific condition, the cause of hair loss, and individual sensitivity to inflammation. By understanding the characteristics and applications of these different types of PRP, hair transplant specialists can customize treatment plans to achieve the best possible results for their patients.
