Hair Regrowth Injections (HRI — PRP-Style Growth Factor Treatment)

Hair Regrowth Injections (HRI) — the clinic's branded PRP-style injectable growth factor treatment for hair loss in men and women. Growth factors derived from the patient's own blood are injected into the scalp to stimulate dormant follicles, improve hair shaft thickness, and slow progressive hair loss. Used as a standalone treatment or as an adjunct to FUE hair transplant surgery to maximise density and graft survival.

Melbourne Hair Restoration offers Hair Regrowth Injections (HRI) — the clinic's branded injectable growth factor treatment using a PRP (Platelet-Rich Plasma) or similar autologous blood-derived growth factor protocol to address hair thinning and progressive hair loss in both men and women. The treatment is listed on the clinic's WhatClinic profile as a distinct procedure alongside FUE transplantation, and is used both as a standalone non-surgical option for patients in the early-to-mid stages of hair loss and as an adjunct intraoperative protocol during FUE surgery to enhance graft survival and promote vascularisation of the transplanted follicles. In a standard PRP-style HRI procedure, a small volume of the patient's blood is drawn and centrifuged to concentrate the platelet-rich fraction, which contains a high density of growth factors including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), and insulin-like growth factor (IGF-1). These growth factors, when injected directly into the scalp at follicular depth, are thought to stimulate the Wnt/beta-catenin pathway in dermal papilla cells — the key molecular signal for follicular cycling and hair shaft elongation — transitioning dormant or miniaturised follicles from telogen (resting) back into anagen (active growth) phase. Melbourne's clinic operates from Collins Place at 45 Collins Street, a premium CBD address in Victoria, Australia, accessible to patients across Melbourne's inner suburbs and the broader metropolitan area. HRI sessions typically take forty-five to sixty minutes and may be repeated at intervals of one to three months depending on the patient's response and hair loss stage. The treatment has no downtime and involves only mild scalp tenderness for twenty-four to forty-eight hours post-injection. Pricing for HRI sessions is not publicly listed by the clinic; contact the Melbourne CBD practice on (03) 9662 1863 for current pricing and to discuss a treatment programme tailored to your hair loss pattern.
