PRP and GFC treatments involve injecting platelet-rich plasma, which is obtained from the patient's blood, into the scalp to stimulate hair growth. QR 678 Hair Growth Treatment is a combination of several growth factors derived from natural sources that have been found to promote hair growth and improve hair density. It is important to note that while Hair Botox contains chemical compounds, it is a safe hair treatment that has been approved by the FDA.
