The risks are minimal because PRP therapy involves injecting your own blood into your scalp, so you aren’t at risk for getting a communicable disease. However during your consultation please be sure to report all your health issues & medications you’re on before the procedure including supplements and herbs. When you have your initial consultation, we may recommend against PRP for hair loss if you: Are on blood thinner medication A heavy smoker A history of alcohol or drug misuse You might also be rejected for treatment if you’ve been diagnosed with: Acute or chronic infections Cancer Chronic liver disease Chronic skin disease Hemodynamic instability Hypofibrinogenemia Metabolic disorder Platelet dysfunction syndromes Systemic disorder Sepsis Low platelet count Thyroid disease
