If you've researched non-surgical hair loss treatments, you've seen both PRP and exosomes promoted as ways to wake up sleeping follicles. They're related but not the same. Here's the honest breakdown.
What is PRP?
Platelet-rich plasma (PRP) is made from your own blood. We draw a small sample, spin it to concentrate the platelets and growth factors, and inject it into the scalp. Those growth factors signal follicles to stay in the growth phase. PRP is well-established and uses nothing but your own biology.
What are exosomes?
Exosomes are tiny messenger vesicles that carry growth factors and signaling molecules between cells — at a much higher concentration than PRP. They're lab-derived rather than drawn from you, and are typically used when a stronger regenerative signal is wanted.
The key differences
- +Source: PRP comes from your blood; exosomes are lab-produced.
- +Concentration: exosomes deliver a denser dose of growth factors.
- +Best for: PRP for early thinning and maintenance; exosomes when you want a stronger boost or are combining with a transplant.
Which is right for you?
Both work best as part of a plan, not a one-off. Many patients combine them with FUE to protect and thicken native hair. The right call depends on your degree of loss, goals and budget — confirmed at a scalp analysis.
