Platelet-Rich Plasma (PRP) therapy offers a non-surgical approach to address hair loss by utilizing components from a patient’s own blood. This treatment involves concentrating platelets from plasma, which are rich in growth factors. These growth factors stimulate cell reproduction, healing, and regeneration. PRP injections enhance blood supply to hair follicles and activate dormant ones, encouraging new hair growth and improving hair thickness.
Typical Initial Treatment Schedule
For individuals undergoing PRP therapy for hair loss, an initial series of treatments is commonly recommended. Most protocols suggest 3 to 6 sessions, spaced about 3 to 6 weeks apart. This intensive initial phase provides concentrated stimulation to the scalp, allowing it to absorb growth factors and respond consistently. It is designed to awaken inactive hair follicles and promote a healthier environment for existing hair.
This spaced approach provides continuous signaling to hair follicles, encouraging them to remain in the active growth phase. Growth factors within the PRP, such as vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF), improve circulation and stimulate cells around the hair follicles. This consistent stimulation helps increase hair density and thickness.
Factors Influencing Session Numbers
The exact number of PRP sessions required varies significantly among individuals. The severity and duration of hair loss play a role; those with mild to moderate thinning often see results with a standard course. More advanced hair loss may require additional sessions.
The specific type of hair loss also affects the treatment plan, as PRP has shown effectiveness for conditions like androgenetic alopecia (pattern baldness) and alopecia areata. Each person’s response is unique, influenced by age, overall health, and natural platelet concentration. A personalized treatment plan is developed after a professional assessment, considering these variables.
Maintenance and Follow-Up Sessions
PRP for hair loss is not a one-time procedure; ongoing maintenance is often necessary to sustain benefits. Hair follicles require continued support to maintain growth and prevent regression. Maintenance sessions are recommended every 3 to 12 months, commonly every 4 to 6 months.
These follow-up treatments reinforce stimulation and preserve gains in hair density and thickness. Without periodic reinforcement, treated hair follicles may gradually revert to their previous state. Regular maintenance ensures consistent stimulation, supporting continued hair growth and overall hair health.
What to Expect During Your PRP Journey
A typical PRP session begins with a small amount of blood drawn from the patient, usually from the arm. This blood is processed in a centrifuge to separate the platelet-rich plasma. The concentrated PRP is then injected into specific scalp areas where hair thinning or loss is present.
The injection process takes around 30 to 45 minutes, with a local anesthetic applied to minimize discomfort. Patients may experience some mild, temporary side effects after the procedure, such as soreness, redness, or slight bruising at the injection sites. These symptoms typically subside within a few days.
Results are not immediate and unfold gradually. Initial improvements, such as reduced shedding or improved hair texture, might be noticed within 2 to 3 months. More noticeable hair growth and density improvements become apparent between 3 to 6 months, with optimal results visible around 6 to 12 months following treatment. Consulting with a qualified healthcare professional is advisable to determine the most appropriate treatment plan for a specific condition.
