When this potent plasma is injected into the scalp, it sets off a powerful biological process that revitalizes dormant hair follicles and rejuvenates the scalp environment. The secret to PRP's regenerative prowess lies in the contents of the platelets, specifically the alpha granules and dense granules, which are released upon activation at the injection site. Let's delve into the essential components within PRP that drive hair regeneration and the precise mechanisms through which they operate: 1. Core Components: The Growth Factors The primary active agents in PRP are growth factors, specialized signaling proteins that communicate with neighboring cells to trigger specific functions like cell proliferation, differentiation, and tissue repair. The high levels of these factors in PRP provide a significant boost to hair follicles. Growth Factor Primary Function for Hair Growth Platelet-Derived Growth Factor (PDGF) Stimulates cell division and proliferation, particularly in dermal papilla cells crucial for new hair shaft formation. It also promotes the growth of new blood vessels (angiogenesis). Vascular Endothelial Growth Factor (VEGF) Essential for angiogenesis, fostering the formation of new blood vessels to ensure hair follicles receive ample oxygen and nutrients for robust growth. Transforming Growth Factor-Beta (TGF-β) Regulates the hair cycle, aiding in tissue healing and transitioning follicles between growth and resting phases to maintain a healthy hair cycle. Epidermal Growth Factor (EGF) Promotes the growth of epithelial cells, including those in the hair follicle lining, and aids in repairing and strengthening scalp tissue. Insulin-Like Growth Factor-1 (IGF-1) A key regulator known to induce and prolong the growth phase of the hair cycle, resulting in longer, thicker hair strands. It supports cell survival and proliferation. Fibroblast Growth Factor (FGF) Stimulates cell growth and differentiation, crucial for wound healing and activating dermal papilla cells to kickstart hair growth. How the Growth Factors Collaborate The combined action of these growth factors is what makes PRP so effective. Upon injection, these concentrated factors saturate the scalp environment, signaling hair follicle stem cells in the bulge area to initiate the growth phase and delay transition and resting phases. This process essentially reverses the shrinking of hair follicles, a hallmark of common hair loss conditions like Androgenetic Alopecia (pattern baldness). 2. Supporting Proteins and Cells In addition to the core growth factors, PRP contains other essential components that enhance the regenerative process: Cytokines and Chemokines These smaller signaling molecules play a vital role in modulating inflammation in the scalp, creating a healthier environment for hair growth by calming chronic micro-inflammation around hair follicles, a known contributor to hair loss. What’s Inside PRP That Helps with Hair Growth? While PRP is initially a liquid, the presence of fibrinogen in the plasma forms a temporary three-dimensional scaffold post-injection. This scaffold acts as a natural delivery system, trapping growth factors and ensuring their gradual release for tissue repair and sustained hair follicle stimulation. White Blood Cells (Leukocytes) The presence of white blood cells in PRP varies based on preparation protocols & [PRP Hair Treatment in Dubai UAE](https:/https://www.glamorousdubai.ae/en/hair-transplant/prp-hair-treatment//). Some clinics filter them out, while others believe they help modulate inflammation and boost immunity, supporting scalp health and healing. Mechanism of Action on the Follicle In essence, high-concentration PRP acts on hair follicles through two primary pathways: Direct Stimulation of Follicle Stem Cells: Growth factors bind to receptors on dermal papilla cells and stem cells, stimulating proliferation and differentiation. This prompts dormant or miniaturized follicles to transition back to the growth phase, producing new hair strands. Vascularization and Nutrient Delivery: Elevated levels of VEGF and PDGF promote new capillary network formation, boosting blood flow to deliver oxygen, vitamins, and minerals directly to the hair follicle root for longer, thicker, and healthier hair growth. By harnessing these sophisticated, natural components, PRP therapy offers a highly effective, autologous method to combat hair loss and stimulate regeneration.
