PRP Hair Restoration

Platelet-rich plasma (PRP) scalp injections at Sona Medical Aesthetics in Newcastle, WA, for hair thinning and early hair loss. PRP prepared from the patient's own blood is injected across the scalp to deliver concentrated growth factors to dormant follicles, supporting the anagen growth phase and slowing miniaturisation. Sessions run approximately sixty minutes. Best results from a series of three monthly sessions.

PRP hair restoration at Sona Medical Aesthetics uses concentrated platelet-rich plasma derived from the patient's own blood to deliver a high dose of growth factors directly to the scalp, with the goal of slowing hair follicle miniaturisation, extending the anagen (active growth) phase of the hair cycle, and reactivating dormant follicles in areas of early to moderate thinning. The treatment is particularly indicated for androgenic alopecia (male and female pattern hair loss), alopecia areata in early or stable phases, and diffuse hair thinning related to stress or nutritional deficiency. The biological rationale centres on the naturally high concentration of growth factors within platelets: upon injection and activation, platelets degranulate and release PDGF, VEGF, TGF-β, EGF, and keratinocyte growth factor (KGF), among others. In the scalp context, PDGF and VEGF in particular are thought to support the neovascularisation around the dermal papilla — the cluster of specialised cells at the base of each follicle that regulates hair cycle transition — improving the metabolic support the follicle receives during the growth phase. KGF (also known as FGF-7) supports the proliferation of keratinocytes in the hair matrix. The combined effect of these growth factors is associated with reduced shedding, improved hair shaft calibre, and reactivation of follicles in the telogen or latent phase. The procedure begins with a blood draw and centrifugation to produce PRP. The scalp is then prepared with topical numbing or micro-injections of local anaesthetic, and PRP is injected across the thinning zones using a mesotherapy technique with multiple small-volume injection points. Sessions run approximately sixty minutes. A standard induction protocol of three monthly sessions is recommended, followed by maintenance injections every three to six months to sustain the follicular biostimulatory environment over time.
