Clinical Q&A
Q: What is the mechanism of action of HGF in hair follicle regeneration?
A: HGF binds the MET proto-oncogene receptor tyrosine kinase expressed on dermal papilla cells and follicular keratinocytes. Receptor activation triggers downstream PI3K/AKT and RAS/MAPK signalling cascades that promote follicular cell proliferation, suppress apoptosis, and stimulate VEGF-mediated perifollicular angiogenesis. This extends the anagen (active growth) phase and promotes transition of miniaturised vellus follicles toward terminal hair production in androgenetic alopecia.
Q: Why is exosome encapsulation superior to free HGF injection for hair treatment?
A: Free HGF has a short plasma half-life (~3–5 minutes) due to rapid enzymatic degradation. Exosome encapsulation protects HGF from extracellular proteases, prolongs local bioavailability at the dermal papilla level, and enables endosomal uptake by target cells — delivering the growth factor intracellularly where it can directly interact with cytoplasmic signalling proteins. Exosomes also carry co-regulatory microRNAs that modulate follicular gene expression.
Q: How many sessions are required and what is the recommended treatment interval?
A: The complete Plenaris protocol comprises 5 sessions spaced 2–4 weeks apart (approximately 3–4 months total). Clinical assessment of treatment response — including dermoscopic evaluation of follicular density and hair shaft calibre — is recommended at session 3 to confirm anagen induction before completing the protocol.
Q: Which alopecia subtypes respond best to Plenaris Exosome HGF treatment?
A: Greatest clinical evidence exists for androgenetic alopecia (AGA, Hamilton-Norwood Stages I–IV) and telogen effluvium. Post-chemotherapy alopecia and traction alopecia also show favourable responses given intact follicular stem cell populations. Cicatricial (scarring) alopecias are typically poor candidates due to irreversible follicular destruction.
Q: What quality and regulatory standards govern the Plenaris Exosome HGF product?
A: Plenaris Exosome HGF is manufactured under ISO 13485:2016 (medical devices quality management) and ISO 9001:2015 frameworks. In Singapore, exosome-based biologics for aesthetic use fall under HSA's oversight of cell, tissue, and gene therapy products (CTGTPs) or as unregistered health products; practitioners should confirm current HSA classification status and applicable clinic licensing requirements before administering.
