Hair PRP: A Nonsurgical Option for Hair Loss and Thinning Hair
Hair PRP, or platelet-rich plasma, is an option for managing hair loss and thinning hair. It uses the patient's own platelets, which contain a high concentration of growth factors, to support cell repair. The plasma is injected into the scalp to stimulate weakened hair-follicle cells, helping them become stronger and function more effectively. This nonsurgical method relies on the body's natural repair mechanisms. Results vary by individual.
Key points
- Hair PRP uses concentrated platelets from the patient's own blood to support hair-follicle cells directly.
- It is a nonsurgical method that may be suitable for people with early-to-moderate hair loss or thinning hair.
- The process requires a physician's expertise in preparing and injecting the platelets to support favorable outcomes.
- Changes appear gradually, and ongoing sessions following a physician's advice may be needed to maintain results over the longer term.
- Because components from the patient's own blood are used, the procedure has a high safety profile and the likelihood of an allergic reaction is very low.
What Is Hair PRP, and How Does It Work on Hair Follicles?
PRP, or platelet-rich plasma, is a blood component obtained by centrifuging a patient's blood to produce plasma containing several times the platelet concentration found in normal blood. These platelets are rich in biological substances called growth factors—proteins that play an important role in the body's natural processes of tissue repair and new-cell formation.
When highly concentrated PRP is injected into affected areas of the scalp, its growth factors act directly on hair follicles that are deteriorating or in a resting phase. The main mechanisms include stimulating new capillary formation, increasing the flow of blood and oxygen to the follicles, stimulating stem-cell division around the follicles, and helping slow the hair-shedding cycle. This may strengthen weakened follicles and enable them to produce thicker, healthier hair strands.
A Closer Look at the Hair PRP Procedure at Mediqueen Clinic
Every stage of the hair PRP procedure at Mediqueen Clinic is closely supervised by a physician to support safety and effectiveness. It begins with a consultation and assessment by a physician (medical license no. 37670) to identify the cause of hair loss and develop an individualized treatment plan. At the start of the procedure, a small amount of blood is drawn from the patient's arm, much like during a routine health examination.
The blood is then placed in a specialized tube and processed in a centrifuge at a precisely controlled speed and duration. This separates it into red blood cells, platelet-poor plasma, and the desired platelet-rich plasma. The physician carefully extracts only the PRP fraction and gently injects it into affected areas of the scalp. A local anesthetic may be used to reduce discomfort during the procedure.
Who May Be Suitable for Hair PRP Treatment?
Hair PRP may produce a favorable response in people with certain types of hair concerns. A physician's assessment is therefore important to determine individual suitability. Groups that commonly may benefit include:
1. Men and women with early-to-moderate androgenetic alopecia whose follicles have not completely atrophied but have become smaller and produce finer hair. 2. People with general hair thinning, where the strands have become finer and weaker, making the hair appear to lack overall volume. 3. People seeking to supplement other treatments, such as oral or topical medication, to improve the management of hair loss. 4. People seeking a nonsurgical option or those who cannot undergo hair-transplant surgery.
Who Should Avoid Hair PRP or Seek Additional Medical Advice?
Although PRP has a high safety profile because it is derived from the patient's own body, precautions still apply, and the treatment is not recommended for certain groups due to potential risks. These include:
1. People with abnormally low platelet counts (thrombocytopenia) or blood-clotting disorders. 2. People with an active scalp infection, open wounds, or severe inflammatory skin disease in the treatment area; these conditions should be managed before the procedure. 3. People who are pregnant or breastfeeding. 4. Patients with cancer, severe liver disease, or a bloodstream infection. 5. People who regularly take anticoagulants or NSAIDs should inform the physician for assessment. Medication may need to be stopped before the procedure, but only as directed by the physician.
Preparing Before and Caring for the Scalp After PRP
Appropriate preparation and aftercare are important factors affecting treatment effectiveness. Before treatment, drink plenty of water to support suitable blood concentration, get adequate rest, avoid alcohol and smoking for at least 24–48 hours, and wash the hair thoroughly on the day of the procedure without applying styling products.
For the first 24 hours after treatment, avoid washing the hair, applying harsh chemicals to the hair or scalp, strenuous exercise that causes heavy sweating, and exposure to high heat, such as a sauna or intense direct sunlight on Pattaya Beach. These measures help reduce the risk of irritation or infection. Normal daily activities may then be resumed, while the physician's instructions should continue to be followed carefully.
Expected Results and Treatment Frequency
It is important to have reasonable expectations. Hair PRP does not produce immediate results; changes appear gradually because the procedure stimulates the body's own repair processes. Changes such as reduced hair shedding or the appearance of new fine hairs may generally become noticeable around 3–6 months after treatment. Results vary by individual, depending on the cause and severity of the condition and the body's response.
Hair PRP is not a one-time treatment. Physicians generally recommend an initial series of approximately 3–5 sessions at intervals of 4–6 weeks to stimulate hair-follicle cells consistently. After the initial program, maintenance sessions may be needed every 6–12 months to preserve the results. The appropriate frequency depends primarily on the physician's assessment.
FAQ
Is Hair PRP Painful?
Pain perception varies by individual. It generally feels similar to ordinary injections into the scalp. At Mediqueen Clinic, the physician focuses on reducing discomfort and may apply a cold compress or topical local anesthetic to the scalp before the procedure to help improve comfort.
How Many Sessions Are Needed Before Changes May Be Seen?
An ongoing series of at least 3–5 sessions, spaced 4–6 weeks apart, is generally recommended. Reduced hair shedding may become noticeable after the second or third session, with more visible changes—such as new fine hairs or hair that appears thicker—developing gradually within 3–6 months after treatment begins. Results and timing vary by individual according to the condition and response to treatment.
How Long Do Hair PRP Results Last?
Hair PRP may provide long-lasting results, but it does not completely stop age-related cellular changes or the effects of hormonal factors. To help maintain the results, physicians often recommend a maintenance session every 6–12 months, depending on the assessment of each patient's scalp and hair.
Can Hair PRP Help with Gray Hair?
PRP primarily works by stimulating hair-follicle activity and supporting the hair-growth cycle. It does not directly affect the production of melanin, the pigment that determines hair color. Therefore, PRP does not directly address gray hair or turn gray hair black; its main focus is the management of hair loss and thinning hair.
