Platelet rich plasma (PRP) is an autologous preparation of human plasma with high concentration of platelets. Platelets release numerous growth factors, which stimulate cell proliferation and differentiation.
The purpose of this research is to investigate the potential of PRP injection for treatment of hair loss. Clinical outcomes will be assessed by noninvasive techniques including dermoscopy, multiphoton microscopy, optical coherence tomography, optical Doppler tomography and multispectral imaging.
