PRP (platelet-rich plasma) hair therapy is a non-surgical option that uses components of your own blood (platelets and growth factors) with the aim of supporting follicle activity and improving hair density over time.
While protocols vary, PRP typically involves:
- Taking a small blood sample
- Processing it to concentrate platelets
- Injecting PRP into thinning areas of the scalp under sterile technique
Set expectations carefully:
- Hair change is gradual; regrowth and density improvements (if they occur) take time.
- Many people require a series of sessions and follow-up.
- Results vary by diagnosis, age, genetics, and overall health.
PRP is most commonly discussed for people with:
- Early to moderate thinning
- Pattern hair loss (androgenetic alopecia)
- People looking for a non-surgical approach (where appropriate)
Your clinician should also explain when PRP is less likely to help (for example, where follicles are no longer viable or where a different diagnosis is suspected).
- PRP uses blood-derived growth factors.
- Regenera Activa® uses cellular micro-grafts (a different mechanism), and some clinics position it as a longer-lasting alternative for suitable candidates.
Because PRP uses your own blood components, it’s generally discussed as a low-allergen option; however, injections can still involve discomfort, temporary swelling, and other risks your clinician should explain.
How many sessions are needed?
Varies by protocol and diagnosis; discuss during consultation.
Can PRP help women as well as men?
Some clinics treat both men and women, depending on diagnosis and suitability.
