Platelet-Rich Plasma (PRP) therapy is now widely available in UK hair clinics, either as a standalone treatment for early hair loss or as an adjunct to hair transplant surgery. With growing commercial interest in the procedure, it is important to understand what PRP actually does and for whom it is genuinely useful.
What PRP Involves
A small amount of blood is drawn, placed in a centrifuge to concentrate the platelet-rich fraction, and the resulting PRP is injected into the scalp using a fine needle. The whole process takes approximately 45–60 minutes and is performed under topical anaesthetic cream to minimise discomfort.
What Platelets Do for Hair
Platelets release growth factors including Platelet-Derived Growth Factor (PDGF), Vascular Endothelial Growth Factor (VEGF), and Epidermal Growth Factor (EGF). These factors stimulate follicle stem cells, promote blood vessel formation around follicles, and may prolong the anagen (growth) phase of the hair cycle.
The Evidence
Multiple controlled studies have shown PRP to be effective in:
- Increasing hair count and density in patients with androgenetic alopecia
- Improving hair shaft diameter
- Reducing daily hair shedding
Effect sizes are modest — PRP is not a dramatic transformation treatment. Results require multiple sessions and maintenance injections every 6–12 months to sustain.
Who Benefits Most
PRP tends to work best for patients with early hair loss and significant miniaturisation — where follicles are thinning but still active. It has limited effect on areas of complete hair loss where follicles are absent.
PRP vs Medical Treatment
Finasteride and minoxidil have a stronger evidence base and greater effect size than PRP for most patients. PRP is a useful complement to medical treatment, particularly for patients who cannot or will not take oral medication.
