KeraFactor has highly concentrated levels of growth hormones and proteins that specifically boost hair growth and affects all 4 stages of the hair life cycle. Kerafactor is coated with nano-liposomes which aid its absorption, allowing for enhanced delivery of growth hormones directly to the hair follicles. Each nano-liposome contains thousands of each specific growth factor. Platelets have variable amounts of growth factors depending on the genetics and health conditions of the person. Platelets also contain growth factors that actually inhibit hair growth. Platelet therapy requires a blood draw, centrifuge, followed by multiple injections into the scalp. Even after numbing medication, the injections can be painful and lead to bruising or hematomas.
