platelet-rich plasma PRP dermal papilla cells DPCs FGFR1 PDGFRα PDGFRB MAPK pathway Akt pathway Wnt signaling pathway GSK-3 β-catenin androgenic alopecia MAPK Akt Wnt

TLDR Activated platelet-rich plasma helps hair growth by boosting growth factors and cell growth pathways in hair cells.

The study from March 18, 2019, demonstrated that activated platelet-rich plasma (PRP) supernatant promotes hair growth by enhancing the expression of key growth factor receptors and activating signaling pathways in cultured human dermal papilla cells (DPCs). Specifically, the PRP supernatant increased the expression of phosphorylated FGFR1, PDGFRα, and PDGFRB, and activated the MAPK and Akt pathways, which are associated with cell proliferation. It also suggested involvement of the Wnt signaling pathway, indicated by decreased GSK-3 levels and increased β-catenin expression. These findings suggest that PRP could be a potential treatment for androgenic alopecia. The study's experiments were conducted with cells isolated from ten healthy volunteers, but the sample size for the assays was n = 3.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.
