What Are Exosomes?
Exosomes are nano-sized extracellular vesicles (30–150 nanometers) derived from stem cells. They carry growth
factors, proteins, and signaling molecules that communicate regeneration instructions to recipient cells —
including hair follicle cells.
Think of them as messengers: while PRP therapy uses your own platelets' growth
factors, exosomes deliver growth factors from lab-cultured stem cells — potentially more concentrated and
consistent.
How Exosome Therapy Works for Hair
- Exosome solution is prepared from a standardized, quality-controlled source
- The scalp is numbed with topical anaesthesia
- Exosomes are micro-injected into the scalp at areas of thinning
- The session takes approximately 30–45 minutes
An Honest Assessment
We believe in telling patients what we know and what we don't:
What the evidence shows:
- Early clinical studies show improvement in hair density and thickness
- No significant side effects reported in published studies
- Theoretical advantage over PRP due to standardized growth factor content
What we don't know yet:
- Long-term data beyond 2–3 years is limited
- Optimal dosing and session frequency is still being studied
- Comparative studies against PRP are few and inconclusive
- Cost-effectiveness compared to established treatments isn't proven
Who Might Consider Exosome Therapy
- Patients who have had suboptimal response to PRP
- Those looking for the latest available options after standard treatments
- Post-transplant patients seeking enhanced graft survival
Who Should Start with Established Treatments First
- First-time patients — PRP and medical management have more data
- Budget-conscious patients — exosome therapy costs more than PRP
- Patients who haven't had blood work or trichoscopy yet (start with proper
diagnosis first)
Cost
Exosome therapy sessions typically cost more than PRP due to the specialized preparation. We discuss exact
pricing during consultation based on treatment area and product used. For PRP pricing comparison, see our PRP
cost page.
