I wrote a popular post on topical finasteride in June 2014. Shortly after, someone from the renowned Hasson & Wong clinic in Vancouver, Canada e-mailed me to let me know that they were now prescribing topical finasteride.
Fast forward to several days ago, Dr. Victor Hasson of Hasson & Wong posted a detailed comment to that blog post on topical finasteride and I thought that his comment deserved its own post. Here is Dr. Hasson’s update:
Our topical finasteride solution that we have been using for the past 2 years has proven to be very effective . It has been used primarily in patients who had been experiencing side effects on the oral drug. These patients have been free of side effects on the topical formulation. This is a good sign that the drug is unlikely to be going systemic via cutaneous permeation. We are currently performing tests using Franz diffusion cells with the The University of Milan to get more data.
Once we have secured a reliable source for dutasteride we will start testing topical formulations with this drug as it will likely be more effective.
A new liposomal formulation of topical finasteride is currently available to our European patients. It has been developed in collaboration with Farmacia Parati in Italy. This preparation can be obtained from this company . You will require a physicians prescription for this as the formulation needs to be compounded on a case by case basis (to comply with European and FDA regulations).

I am impressed by the efforts that the Hassson & Wong clinic is putting into creating their own topical finasteride and topical dutasteride products. A 2007 study on liposomal delivery of finasteride suggests that this route will be effective. If the results from these topical products consistently prove to be as good or superior to oral finasteride and oral dutasteride while at the same time lead to fewer side effects, this development will be a game changer.
