PRP (platelet-rich plasma): therapy is a medical treatment that uses a patient's own blood plasma, which is rich in growth factors and platelets, to promote healing and tissue regeneration. It is used in various medical fields such as orthopedics, sports medicine, dentistry, and also in dermatology.

In dermatology, PRP therapy is used to promote hair growth, improve skin texture and tone, and reduce the appearance of fine lines and wrinkles. The treatment involves taking a sample of the patient's blood, which is then processed in a centrifuge to separate the platelets from the other blood components. The concentrated platelets are then re-injected into the scalp, face, or other areas of the body, where they release growth factors that stimulate the production of new collagen and blood vessels and promote tissue repair.

PRP therapy is considered safe and effective for treating hair loss, and it is a non-surgical, non-invasive option for those who want to improve their hair growth or skin texture. However, it's important to consult with a licensed professional who is trained and experienced in PRP therapy to determine if it is the right treatment for you.
