"PRP Hair Treatment Toronto " PRP stands for Platelet-Rich Plasma. It’s a treatment that involves drawing a small amount of a patient’s blood, processing it to concentrate the platelets, and then injecting this plasma back into the body at the site of injury or concern to promote healing and tissue regeneration. The frequency of PRP injections for hair regrowth can vary depending on the individual’s specific needs and goals. Typically, an initial series of treatments is done every few weeks, over several months (e.g., once a month for 3-4 sessions), followed by maintenance sessions every 4-6 months to sustain the results. The exact frequency and number of treatments may be adjusted based on the response to the therapy and the individual’s goals.
