Hair thinning is one of the most emotionally loaded concerns patients bring to a consultation, which unfortunately also makes it one of the most heavily marketed with treatments that overpromise. Two of the most commonly discussed — PRP and hair filler — are genuinely evidence-supported, but they work in different ways and suit different stages of thinning.
PRP: supporting existing follicles
PRP for hair thinning uses your own concentrated platelets, injected into the scalp to support blood supply and growth signalling around existing follicles. It’s best suited to earlier-stage thinning, where follicles are miniaturising but still present and active — PRP therapy has little to offer an area that’s already gone fully bald, since there’s nothing left to stimulate.
Hair filler: a newer, more targeted approach
Dr CYJ hair filler, sourced by clinics from wholesale suppliers for in-clinic use, takes a different approach — a peptide-and-nutrient complex injected specifically to support the scalp environment around thinning areas. Like PRP, it works best as prevention and early intervention rather than a fix for advanced hair loss.
Where mesotherapy fits in
Some clinics build hair protocols around scalp mesotherapy — micro-injections of vitamins and actives to support the follicle environment — often layered alongside PRP or hair filler rather than instead of either. Choosing the right mesotherapy brand matters here, since formulations vary considerably in what they’re actually designed to support.
Setting expectations early
None of these treatments reverse advanced pattern hair loss, and any provider claiming otherwise is overselling. What they can do, in the right candidate and started early enough, is slow thinning and support the follicles that are still active — which is a genuinely different promise to “hair regrowth” as it’s often marketed.
The real first step
Before choosing between these options, a proper scalp assessment to establish exactly what stage of thinning you’re dealing with will do more for the outcome than the specific treatment chosen.
