PDO-Based Thread-Embedding Therapy for Hair Loss Management: Mechanistic Hypotheses

The document discusses the potential of polydioxanone (PDO)-based thread-embedding therapy for managing hair loss. It proposes a mechanistic hypothesis where PDO threads may influence the scalp's microenvironment by shifting inflammation from M1 to M2, regulating oxidative stress, enhancing IL-10 signaling, and suppressing NF-κB activity. Additionally, PDO degradation might aid in extracellular matrix remodeling and VEGF-related microvascular changes, potentially supporting hair follicle regeneration. While PDO threads could act as structural and bio-responsive immune modulators, the review emphasizes that these are hypotheses requiring further experimental and clinical validation to confirm their effectiveness in hair loss management.
