Platelet-rich plasma (PRP) injections have gained popularity for medical and cosmetic purposes, including hair restoration. PRP is a concentrated form of plasma taken from a patient's own blood, and contains platelets and growth factors that are thought to help repair tissue. In hair restoration, platelet-rich plasma (PRP) injections stimulate hair growth and thickness by injecting concentrated platelet-rich plasma (PRP) into the scalp. The mechanism involves growth factors that stimulate hair follicles and promote hair regeneration. Multiple sessions spaced weeks apart are usually needed for best results. Results vary between individuals, and maintenance sessions may be needed. Platelet-rich plasma (PRP) treatment is safe, with minimal risks such as mild swelling or discomfort. Consultation with a qualified professional is essential before considering PRP therapy or any hair restoration treatment to determine suitability and discuss options.
