PRP Hair Therapy (Eigenblut-Therapie)

PRP hair therapy (Eigenblut-Therapie) at Haarklinik Hannover Dr Diaby uses a concentrated preparation of the patient's own platelet-rich plasma to deliver growth factors directly to the scalp and hair follicles. A small blood draw is centrifuged to isolate the platelet concentrate, which is then injected intradermally across the thinning zone. The treatment aims to reduce hair shedding, prolong the anagen growth phase, and support follicle health in early to moderate androgenetic alopecia. PRP is also used as a post-transplant protocol to support graft survival and accelerate recovery. Sessions run approximately sixty minutes.

PRP (Platelet-Rich Plasma) hair therapy — known in Germany as Eigenblut-Therapie — at Haarklinik Hannover Dr Diaby is a non-surgical biological treatment for hair loss that uses the patient's own blood-derived growth factor concentrate to stimulate follicular activity. The procedure begins with a venous blood draw of 15–30 mL, which is placed into specialised anticoagulant-treated tubes and processed in a centrifuge at calibrated speed and duration to separate the blood into its component fractions: erythrocytes (red cells) at the base, a buffy coat layer containing platelets and white cells, and cell-poor plasma at the top. The intermediate platelet-rich layer is carefully aspirated to produce the PRP concentrate — typically achieving a platelet concentration three to five times above whole-blood baseline. Platelets contain alpha granules loaded with growth factors including platelet-derived growth factor (PDGF), transforming growth factor beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF-1). When injected into the scalp dermis at the level of the dermal papilla — the vascular and neural structure at the base of each follicle — these growth factors bind to receptors on dermal papilla cells, stimulating proliferation and upregulation of the signals that maintain follicles in the active anagen growth phase. The clinical mechanism is believed to involve prolonging anagen phase duration, promoting miniaturised follicle recovery in androgenetic alopecia, and increasing local vascularity around the follicular unit. Haarklinik Hannover offers PRP hair therapy as a standalone treatment for patients with early-stage hair loss who are not yet candidates for surgery, and as an adjunct protocol after FUE hair transplant, where growth factor delivery to the recipient zone may support graft survival and accelerate the early vascularisation of transplanted follicles. The standard initial course at the clinic is three sessions spaced four to six weeks apart, followed by maintenance sessions every six to twelve months depending on individual response. Scalp numbing cream is applied prior to injection to minimise discomfort during intradermal delivery across the treated zones.
