This is a treatment that can do many things. PRP - platelet-rich protein - is a blood product, from your own body, that has a high concentration of growth factors. Depending on how we use it and where we inject it, it can: stimulate hair growth in men and women; smooth fine lines; brighten and even out the skin tone. The number of tubes we use will depend on the treatment area. Retreatment can be every 6-12 months, depending on the treatment area.
