When it comes to hair loss, patients often ask: "What actually works?" You’ve probably heard of minoxidil and finasteride — but what about PRP (platelet-rich plasma)? At Dunedin Medical & Aesthetics Clinic, we specialise in evidence-based treatments — and the results may surprise you.
In this article, we break down the science behind the three most talked-about options: PRP vs minoxidil vs finasteride — so you can make an informed decision.
Understanding the Key Players: PRP, Minoxidil, and Finasteride
Minoxidil is a topical vasodilator that increases blood flow to hair follicles. It’s commonly used as a foam or lotion.
Finasteride is an oral prescription medication that blocks DHT, a hormone known to shrink follicles.
PRP (Platelet-Rich Plasma) is an autologous treatment that uses your own blood to extract growth factors, which are then injected into the scalp to stimulate follicle repair and growth.
While minoxidil and finasteride are pharmaceutical, PRP is regenerative — and that’s a major distinction for many patients.
PRP vs Minoxidil: What Clinical Studies Show
Recent studies suggest that PRP often yields better early-stage results than minoxidil in terms of increasing hair density and thickness.
Unlike minoxidil, which must be applied daily and can irritate the scalp, PRP treatments are spaced out and build upon each other. PRP also directly targets the follicle with growth factors like VEGF and IGF-1.
For patients looking for a natural, drug-free approach, PRP offers a strong alternative to long-term topical treatments.
Finasteride vs PRP: Addressing the Hormonal Factor
Finasteride blocks the enzyme 5-alpha reductase, preventing the formation of DHT. It’s effective, but some patients experience side effects such as low libido or mood changes.
PRP, on the other hand, supports healthy follicle signalling and inflammation reduction without altering systemic hormones. In many comparative studies, patients report a higher satisfaction rate with PRP — particularly those who prefer a hormone-neutral solution.
This makes PRP an appealing option for both men and women seeking the best hair loss treatment in NZ.
