Pattern hair loss, also known as androgenetic alopecia, is a prevalent condition affecting a significant portion of the adult population, particularly males, but also females, between the ages of 18 and 55. This condition is characterized by progressive hair thinning and loss, which can impact an individual's psychological well-being and quality of life. Recent therapeutic approaches have explored various interventions, among which Platelet Rich Plasma (PRP) therapy has garnered considerable interest due to its regenerative potential. To understand the efficacy and mechanisms of PRP in promoting hair regrowth, a conceptual framework grounded in biological and clinical evidence is essential.

A suitable conceptual model to explain the relationship between PRP and hair growth is the Biological Response Model, which posits that PRP induces tissue regeneration through the release of growth factors stored within platelets. These growth factors, including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor-beta (TGF-β), stimulate cellular proliferation, angiogenesis, and extracellular matrix remodeling in the scalp. This cascade of biological processes ultimately enhances hair follicle viability and promotes new hair growth.

In this model, the independent variable is the application of PRP, while the dependent variable is the extent of hair regrowth. The model conceptualizes that the biological response to PRP's growth factors mediates the relationship between treatment and hair regrowth. The concepts within this framework—namely, PRP treatment, growth factor release, cellular proliferation, angiogenesis, and hair follicle regeneration—are defined as follows:

  • PRP Treatment: A blood-derived product enriched with platelets, prepared through centrifugation, administered via injections into the scalp.
  • Growth Factor Release: The liberation of bioactive proteins from platelets upon activation, which stimulates cellular processes.
  • Cellular Proliferation: The increase in the number of hair follicle cells and surrounding dermal papilla cells, leading to follicle revitalization.
  • Angiogenesis: The formation of new blood vessels within the scalp tissue, improving nutrient and oxygen delivery to hair follicles.
  • Hair Follicle Regeneration: The process by which damaged or miniaturized hair follicles regain their growth potential.

The relationships among these concepts are sequential and causal within the model. PRP application leads to the release of growth factors, which in turn promote cellular proliferation and angiogenesis. These biological effects collectively enhance the viability of hair follicles, encouraging regrowth.

Applying this model to the current study involves examining the effect of PRP injections on hair regrowth in patients aged 18-55 with pattern hair loss. The model suggests that increased levels of growth factor activity induced by PRP will correlate with measurable improvements in hair density and thickness, observable through clinical assessments and photographic documentation.

The expected relationships among the variables are that the administration of PRP (independent variable) will positively influence the biological responses—growth factor release, cellular proliferation, and angiogenesis—which collectively will lead to an increase in hair regrowth (dependent variable). Conversely, failure to induce sufficient biological responses may result in minimal or no hair growth, emphasizing the importance of optimizing PRP preparation and application protocols.
