Thank you for your question. I understand that you want to know if PRP therapy is an effective solution for hair fall or hair thinning. I can certainly give you some insight on this matter as I am a hair specialist and the founder of Trichostem Hair Regeneration centers, and have been very active in the use of PRP as an alternative hair loss solution. I am also a Board-certified cosmetic surgeon, certified by the American Board of Cosmetic Surgery, and a Fellowship-trained oculofacial plastic surgeon practicing in Manhattan and Long Island for over 20 years.Hair loss is essentially caused my male or female pattern hair loss, or genetic hair loss. The more popular treatments for this are drugs such as minoxidil and finasteride.In our practice, we’ve developed a technology called Hair Regeneration, which makes use of a combination of platelet-rich plasma (PRP) and extracellular matrix. Platelet-rich plasma is a material derived from your own blood, and contains healing and growth factors, while extracellular matrix is derived from organic tissue and is also intended for wound-healing. Over the years, it was observed that a side effect of the wound-healing capabilities of platelet-rich plasma appeared to stimulate hair growth and hair thickening, particularly when used alongside a hair transplant. However, it was also observed that PRP, when used alone, does not stop hair loss or hair thinning, even with continuous injections.Our Hair Regeneration treatment is formulated to stop hair loss progression and thicken existing thinning hair, so it’s actually a reversal of the thinning process. The treatment is not designed to bring back 100% of your hair, and there are some cases wherein it does not work for some people, but nevertheless, it has been able to produce impressive results in more than 99% of male pattern hair loss patients. For those who do not respond right away, we can do additional injections based on a customized approach to help improve results. We have treated many people from all over the world and we’ve come to understand that the earlier we catch someone, the better the results.So to answer your question, PRP can stimulate short-term hair growth, but it cannot stop hair loss by itself. We would however use it in combination with our Hair Regeneration system. I would suggest that you look into this treatment, as it certainly is a game-changing treatment in the field of regenerative medicine. We’ve actually gotten much better results by salvaging thinning hair. In fact, the results we’ve been able to get have surpassed that results of regular hair transplant procedures.So I hope that was helpful and I wish you the best of luck!This personalized video answer to your question is posted on RealSelf and on YouTube.
