Platelet-Rich Plasma for hair loss and thinning prevention is an effective treatment for various hair loss conditions which cause the hair follicle to become weak and inactive. When PRP is injected into the scalp, it promotes blood flow to the follicles which in turn increases the average hair follicle count and improves hair thickness, health, and strength. As with all PRP treatments, certain medical conditions that affect the platelets are contraindicated. The cost of PRP hair rejuvenation is $1200 per session or $3400 for 3 sessions. On average, 3-6 sessions are recommended and can be scheduled every 30 days.
