PRP Hair Growth Therapy

PRP scalp injection therapy for hair growth at Marina Medspa in Brentwood, Los Angeles. Patient blood is drawn, centrifuged to concentrate platelets, and injected into the scalp to stimulate follicle activity. A series of three to four initial sessions is recommended, with results developing over three to six months. Pricing is by consultation; LA market rates typically $1,000–$1,500 per session.

PRP (platelet-rich plasma) hair growth therapy at Marina Medspa harnesses the patient's own blood to deliver a concentrated dose of growth factors directly to the scalp. The procedure begins with a standard blood draw, after which the sample is processed in a centrifuge to separate the plasma layer enriched with platelets — typically achieving three to five times the baseline platelet concentration. The resulting PRP is then injected across the scalp using a fine needle at multiple sites, targeting the follicular units in areas experiencing thinning or reduced density. Platelets release a cocktail of growth factors — including platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), transforming growth factor (TGF), and insulin-like growth factor (IGF-1) — which are involved in stimulating follicular cell proliferation, angiogenesis around the follicle, and the transition of resting follicles back into the active growth phase. PRP hair therapy has been studied across multiple randomised controlled trials showing improvement in hair density, hair shaft diameter, and patient-reported hair count in androgenetic alopecia (male and female pattern hair loss), with evidence also accumulating for alopecia areata. Marina Medspa uses the Eclipse PRP system — the same centrifuge platform used for the clinic's Eclipse MicroPen PRP facials — ensuring consistent concentration of the PRP product. A standard initial series of three to four sessions is spaced four to six weeks apart, with results typically becoming visible at three to six months following the start of treatment. Maintenance sessions every six to twelve months sustain the improvements. This service is performed under physician supervision by the clinic's clinical team. Patients in Brentwood, West LA, Santa Monica, Pacific Palisades, and the broader Westside of Los Angeles seeking a non-surgical, drug-free approach to hair loss are the primary client base.
