What is PRP Platelet Rich Plasma?
Simply put, it involves extracting your own blood and separating out the platelets and plasma by spinning it in a centrifuge. Once the red blood cells are separated, the plasma, now concentrated with platelets, is injected back into your scalp. The thinking goes that since platelets play a crucial role in healing, providing a concentrated dose to your hair follicles will stimulate hair growth and therefore, reverse hair loss.
How does PRP work for Hair loss?
Consider the radical idea that flooding a body part with platelets speeds up healing. PRP contains cytokines, which are small protein molecules secreted by cells of the immune system. Cytokines signal the cells around them to move towards inflammation, infection and areas of trauma. They have been shown to stimulate hair follicles and their functioning.
Hair loss is a result of hair follicles that are damaged, and often cut off from their supply of nutrients and proteins. This damage is caused by a variety of things that can interfere with the natural hair growth cycle. This includes illness, medications, and of course genetic pattern balding. Male pattern baldness is believed to be largely caused by the endogenous androgen hormone known as dihydrotestosterone (DHT).
How long before you see results?
As with any hair loss treatment (excluding transplantation), it takes months for the follicle to strengthen and produce the visible results of a stronger healthier hair. The signs of new hair growth can usually be seen 4-6 months after the PRP injections. The hair continues to become stronger and thicker for up to 15 months after treatment, but continued PRP injections are required to maintain the results and avoid regression of the hair growth.
