I was not planning to write a new post on finasteride anytime soon. However, the latest news from South Korea is highly interesting and cannot be ignored. Researchers have successfully tested finasteride injections as a new potential treatment for hair loss. They have developed a unique finasteride-loaded microspheres delivery system for these injections.
Best of all, you only need to get one injection treatment per month. Worst of all, the current research is in mice. However, the scientists seem to be confident that this will work in humans too.
Finasteride Injections Superior to Oral Finasteride
Most importantly, the hair growth results from the finasteride-loaded microsphere injections were superior to those from oral finasteride. Dr. Kim Beom-joon from Chung-Ang University Hospital led this work. The researchers also published an important related paper in June 2019 titled: “Development of finasteride polymer microspheres for systemic application in androgenic alopecia.”
The 5α-reductase inhibitory effect of the finasteride-loaded microspheres lasts for 4 to 8 weeks following one single injection. The injections and finasteride delivery technology are manufactured by Inventage Lab. Dr. Kim states that by minimizing the intake of finasteride, potential side effects such as erectile dysfunction and decreased libido would be reduced.
We have all been waiting patiently for many years for topical finasteride to get released. However, if Polichem does not release P-3074, it seems like we will never get a globally reliable version of topical finasteride. In that case, finasteride injections would be especially appreciated.
Note that in 2017, we already read about mesotherapy (injections) with dutasteride giving great hair growth results. Maybe we will soon get finasteride injections to treat our hair loss too. And in this case, via a delivery system designed by a professional biopharmaceutical company.
