Platelet-rich plasma (PRP) therapy involves injecting concentrated growth factors from your own blood into the scalp to stimulate follicles. Evidence suggests it can be effective for androgenetic alopecia, with studies showing improved hair density in 70–80% of patients. Results typically require 3 initial sessions and maintenance every 6–12 months.
PRP (platelet-rich plasma) therapy shows genuine clinical evidence for androgenetic alopecia (pattern hair loss). Multiple trials show increased hair count and density at 3–6 months. It's expensive ($1,500–$4,000 per course), requires multiple sessions, and results diminish over time requiring maintenance treatments. It does not address the scalp inflammation mechanism and works best in people with some remaining active follicles.
PRP involves drawing a small amount of your blood, spinning it in a centrifuge to concentrate the platelet-rich plasma, and injecting it into areas of hair loss. Platelets contain growth factors (PDGF, VEGF, IGF-1) that stimulate cell proliferation and may reactivate miniaturised follicles.
The mechanism is about growth factor delivery — stimulating follicle activity — rather than addressing the inflammatory environment. This is an important distinction.
A 2017 systematic review in the Journal of the American Academy of Dermatology found PRP generally effective for androgenetic alopecia, with most studies showing increased hair density and reduced shedding. However, study quality varied, protocols weren't standardised, and long-term data was limited.
Important: PRP won't work well on heavily scarred or fully dormant follicles. And it doesn't address scalp inflammation — which may be why some patients see good initial results that fade. Combining PRP with an anti-inflammatory approach like ThriivX H3 may extend and improve results.
Before a $2,000 PRP course, addressing scalp inflammation with ThriivX H3 is worth trying — it targets a root cause PRP doesn't touch.
