Finasteride is one of the most effective treatments for androgenic alopecia, also known as male-pattern hair loss.
Finasteride has been available for years in Canada and is very effective. However, it can result in some undesirable side effects. While these are relatively uncommon, the fear of finasteride side effects can make some men hesitant to begin this hair loss treatment.
Luckily, there’s an alternative version of finasteride that results in fewer side effects: topical finasteride.
In this article, we’ll explain everything you need to know about topical finasteride in Canada. We’ll cover what it is, how it works, what side effects may occur, and where to buy topical finasteride in Canada.
Finasteride is a prescription medication for male pattern hair loss, often known by its brand name Propecia. It’s been found to be very effective: in about 83% of men it can stop hair loss, and in about 63% it actually causes hair regrowth.
Finasteride works by blocking the enzyme, 5α-reductase, that converts testosterone to DHT. DHT is what causes male-pattern hair loss, so finasteride works by lowering DHT concentrations.
Finasteride, together with dutasteride and minoxidil, are the most effective treatments that we currently have for hair loss. A combination of oral finasteride with topical minoxidil is the gold standard for hair loss treatment in Canada.
Finasteride is usually taken orally in pill form, but recently scientists have developed a topical version of it that comes as a gel or liquid solution. Rather than working systemically, as the oral version does, topical finasteride gel permeates the scalp and starts working directly around the hair follicles.
Topical finasteride gel works the same way as the oral version—by reducing DHT. Once it permeates into the scalp, topical finasteride blocks the 5α-reductase enzyme from breaking down testosterone into DHT. By blocking the synthesis of DHT, it protects the hair follicles and keeps them healthy so they can continue to produce healthy, thick hair.
The primary benefit of topical finasteride is that it doesn’t have the same side effects of regular finasteride.
Regular finasteride is considered safe and well-tolerated for most people. But, there can potentially beare some side effects. Most worrying for some guys are the sexual side effects: oral finasteride can sometimes lead to erectile dysfunction, decreased libido, and ejaculatory dysfunction, among others.
These are uncommon; studies consistently find that only between 3.4% to 15.8% of individuals experience side effects.
Still, some men prefer not to take the risk. Topical finasteride provides an option with a different safety profile.
So what are topical finasteride side effects?
This is a relatively new medication, so there has not been as much research done on topical versions of finasteride as there have been on the oral forms.
Still, the research suggests that topical finasteride side effects are minimal. No studies have reported any serious side effects as a result of using finasteride topicals. Minor side effects have been reported in some studies; these include scalp irritation, erythema, and contact dermatitis.
Users of finasteride topical gels may also notice some shedding. This is normal—the medication often causes your hair to shed and then begin a new growth phase. Shedding is a sign the medication is working.
So, does topical finasteride work?
But it’s important to keep in mind that topical finasteride is newer, so there is less high-quality research that has been done on it. In particular, there haven’t yet been any large randomized controlled trials (RCTs) that test topical finasteride. RCTs are the “gold standard” for testing medications.
So, yes, the data we have suggests that topical finasteride can certainly be effective. But scientists are currently more confident in what they know about the effectiveness of oral finasteride than they are for the topical versions.
One caveat is that it appears that not all finasteride topical products are created equal. The research is ongoing, but it appears that some formulations are better than others.
Topical finasteride liposomal gel is not widely available in Canada—it is offered by only a handful of clinics. Even when it is available, some of those clinics have a waiting list of up to four months.
