Thinning and recent hair loss? PRF (Platelet Rich Fibrin) promotes hair growth by stimulating the cells (such as stem cells) in the hair follicle’s microenvironment. Procedures must be performed in a series of 4-6 treatments, repeated every 4-6 weeks. Hair can continue to thicken 6-12 months after treatment. ***This treatment requires us to draw your blood – stay hydrated 24 prior to your appointment. Prices start at $500.
