Hair loss is a common concern affecting both men and women. As a dermatologist with years of experience in treating various hair and scalp conditions, I often recommend Platelet-Rich Plasma (PRP) therapy as an effective solution for hair thinning and hair loss. PRP is a minimally invasive, natural treatment that stimulates hair growth by harnessing the healing power of your own blood.
How Does PRP Work?
PRP therapy works on the principle of using the body’s natural healing process to stimulate hair follicles. Our blood contains platelets that are rich in growth factors—proteins that promote tissue repair and regeneration. When PRP is injected into the scalp, these growth factors:
✅ Stimulate dormant hair follicles
✅ Increase blood supply to the hair follicles
✅ Extend the growth phase of the hair cycle
✅ Improve the thickness and density of hair
Procedure Overview
PRP for hair loss is a simple, safe, and quick procedure that typically takes about 30 to 45 minutes. Here’s a step-by-step overview of the process:
- Blood Draw: A small amount of blood (usually about 10–20 ml) is drawn from your arm, similar to a routine blood test.
- Centrifugation: The blood sample is spun in a centrifuge machine to separate the platelets from the red blood cells and plasma.
- Preparation: The platelet-rich plasma is collected and prepared for injection.
- Injection: Using a fine needle, the PRP is injected into the areas of the scalp experiencing hair thinning or hair loss. A local anesthetic may be applied to minimize discomfort.
Number of Sessions Required
For optimal results, a series of treatments is usually recommended:
➡️ Initial Phase: 3–4 sessions, spaced 4–6 weeks apart
➡️ Maintenance Phase: A follow-up session every 4–6 months to maintain the resultsMost patients begin to notice visible improvements in hair thickness and density after the first 3–4 months of treatment.
Post-Procedure Care
Proper aftercare enhances the effectiveness of PRP therapy and ensures a smooth recovery:
✅ Avoid washing your hair for 24 hours after the procedure.
✅ Avoid hair products and chemical treatments (like coloring) for at least 48 hours.
✅ Limit sun exposure and avoid direct heat (like blow-drying) for 48 hours.
✅ Avoid strenuous exercise and heavy sweating for 24 hours.
✅ Refrain from touching or massaging the treated area for a few days to allow the PRP to settle in the scalp.
✅ If you use topical treatments like minoxidil (Rogaine) or any other medicated sprays, refrain from applying them for at least 48 hours after the procedure to prevent irritation and ensure maximum absorption of the PRP.
Who Can Benefit from PRP?
PRP therapy is most effective for individuals with:
✔️ Early-stage hair thinning
✔️ Androgenetic alopecia (pattern baldness)
✔️ Weak hair growth after a hair transplant
✔️ Stress-related hair loss
PRP is a safe and effective option for hair loss, particularly for those seeking a natural solution without the need for surgery or medications. As a dermatologist, I have witnessed remarkable improvements in my patients’ hair health and confidence through PRP therapy. If you’re struggling with hair thinning or loss, consult with a qualified dermatologist to determine if PRP is the right choice for you.
