PRP is believed to stimulate hair follicles by increasing blood flow, promoting healing, and encouraging the growth of new hair. The growth factors in the platelets help in regenerating damaged tissue and can help revitalize hair follicles, leading to improved hair thickness and density.

The procedure typically involves the following steps:

1. Blood collection: A small sample of your blood is taken.

2. Processing: The blood is processed in a centrifuge to separate the platelets from other blood components.

3. Injection: The concentrated PRP is then injected into the scalp, focusing on areas with thinning or lost hair.

PRP therapy is often used to treat conditions like androgenic alopecia (male and female pattern baldness) and other types of hair loss. It is generally considered safe since it uses your own blood, reducing the risk of an allergic reaction.

However, multiple sessions may be required to see noticeable results, and the treatment's effectiveness can vary from person to person.
