Platelet-rich plasma (PRP) therapy for hair restoration presents specific biochemical challenges in maintaining growth factor viability and achieving targeted delivery. Current clinical data shows that while PRP contains key proteins like PDGF and VEGF at concentrations of 200-800 pg/mL, these levels must be carefully preserved during preparation and precisely delivered to reach the follicular target depth of 1-1.5mm.

The core challenge lies in optimizing both the biological composition of PRP preparations and their physical delivery mechanisms to achieve consistent therapeutic effects across different patterns of hair loss.

This page brings together solutions from recent research—including enzymatic extraction methods for follicular microfibrils, decomposed platelet concentrates with elevated RANTES levels, and microneedle delivery systems with adjustable depths. These and other approaches focus on enhancing both the preparation and administration of PRP treatments while maintaining growth factor stability and bioavailability.

The decomposed platelet concentrate is stored resuspended in liquid medium like plasma to prevent platelet lysis. It provides benefits like angiogenesis, collagen formation, and cell division for tissue regeneration when used in surgeries and wound healing.
