As a dermatologist deeply committed to providing innovative solutions for hair loss, I am excited to share my insights on Platelet-Rich Plasma therapy or PRP which I have practised since 2012. This treatment has garnered attention in recent years for its results in promoting hair growth. Here’s an overview of PRP, how it works, its benefits, and what you can expect if you’re considering it.
What is PRP?
PRP therapy harnesses the body’s natural healing abilities by using components derived from your own blood. The process begins with a simple blood draw, which is then processed to extract a concentrated form of plasma that is rich in platelets. These platelets upon activation release certain growth factors that are crucial for repair and regeneration. So, it’s actually a cocktail with certain vitamins, which make hair root follicles stronger.
The procedure is a no-touch technique, as the blood is drawn into pre-filled tube containing agents for platelet activation, then centrifuged as per the protocol chosen. e-filled tubes containing agents for platelet activation, then centrifuged according to a precise protocol. The preparation itself is an art—much like a Michelin-starred chef perfecting exotic dishes like yellowtail or baked aubergine. Similarly, the right PRP, skillfully prepared and administered at the right time, becomes the ultimate antidote to hair thinning and baldness.
When injected into the scalp, the growth factors in PRP stimulate and revitalise hair follicles, and restore hair. Yes, injected. It’s the pain and gain part.
The key mechanisms
Stimulation of hair growth: The growth factors encourage the proliferation of cells in the hair follicle, promoting their transition to the anagen phase—the growth phase where we ideally want our most hair to be.
Improved Blood Supply: PRP enhances the blood supply to the hair follicles, ensuring they receive an adequate supply of vitamins, nutrients and oxygen.
Strengthening of Hair Strands: By nourishing the follicles, PRP can lead to thicker, much healthier hair.
As both a practitioner and a researcher in dermatology, I have seen firsthand the transformative effects of PRP therapy.

Some key positives:
Natural solution: Since PRP utilises your own blood, the risk of an allergic reaction is significantly minimised. That’s why I always perform it immediately after a hair transplant procedure—it’s like giving the first nourishment to freshly sown crops. To me, hair root transplantation is akin to planting seeds, and PRP is the essential first feeding to help them thrive.
Zero downtime: Patients can typically return to their daily activities shortly after the procedure, making it a convenient option as a lunch-time procedure with no downtime.
Non-surgical: PRP is a non-invasive treatment, avoiding the complexities and risks associated with surgical hair restoration methods but if you have too much balding don’t expect amazing results.
Evident results: Many patients notice visible improvements in hair density and health after just a few sessions, leading to enhanced self-esteem and confidence for sure. The number of sessions required for the complete procedure depends on your platelet levels, overall immunity (including your body’s vitamin levels), and the expertise of your doctor in preparing and administering PRP.
What to expect during treatment
In my practice, I recommend an individualised treatment protocol based on each patient’s specific needs.
Most patients undergo three to four PRP sessions spaced about four to six weeks apart to maximise results. I generally give a bigger gap in women than men but it all depends on age, concern,etc. To sustain the benefits, I usually suggest maintenance sessions every four to six months, tailored to the individual’s hair growth response.
Who is a good candidate for PRP?
PRP therapy is effective for various types of hair loss, including androgenetic alopecia (pattern baldness) in both men and women, often yielding faster and more notable results in women. It is also beneficial for autoimmune conditions like alopecia areata, lichen planopilaris, and morphea scalp. However, individual factors and specific conditions must be assessed, making a comprehensive consultation essential to determine suitability for treatment.
Safety considerations
The therapy is generally safe, as it uses your own blood. However, like any medical procedure, it is not without potential side effects. Patients might experience mild discomfort or pain at the injection site. They might also see temporary redness or swelling. There are also rare cases of infection and other complications.
PRP therapy remains a standout treatment in combating hair loss. While advancements like stem cells and exosomes are showing promise and I’m currently exploring these to improve outcomes, I firmly believe that conventional PRP continues to deliver excellent results when the candidate is right and the treatment protocol is meticulously followed.
Science is ever-evolving, and as someone committed to continuous learning, I would like to treat at least 500 cases of various types of hair loss with the new PRP methods and observe results over three to six months before making definitive claims. Until then, for those experiencing hair thinning, early stages of hair loss, or seeking non-surgical solutions, PRP therapy with a trusted dermatologist remains an excellent option.
