Try at your own risk! I recently noticed businesses selling topical Finasteride! Finasteride, commonly known by it’s brand name Propecia, is usually taken in pill form and is a prescription drug. So I’m not sure if these guys are selling a topical containing Finasteride legally, or even if the product really contains Finasteride. So if you decide to try one of these products, try it at your own risk. As far as I know it’s illegal to sell Finasteride without prescription.
If you’re interested in buying the one pictured here, just search eBay for Finasteride.
Topical Finasteride for Hair Growth Promotion and Hair Loss Prevention: Does it Work?
The idea behind Finasteride is that applying the medication to the head, or consuming it orally, reduces dihydrotestosterone (DHT) levels. DHT causes hairs on the head to minaturize over a period of several years until they no longer grow.
According to a 2015 study titled Topical Minoxidil Fortified With Finasteride: An account of maintenance of hair density after replacing oral finasteride:
Of the 45 patients who underwent a continuous treatment for AGA, 84.44% maintained a good hair density with topical minoxidil-finasteride combination.
A systematic review of numerous randomized controlled trials was also conducted in July of 2017, which came back with the following results:
A meta-analysis was conducted separately for 5 groups of studies that tested the following hair loss treatments: low-level laser light therapy in men, 5% minoxidil in men, 2% minoxidil in men, 1 mg finasteride in men, and 2% minoxidil in women. All treatments were superior to placebo (P < .00001) in the 5 meta-analyses”
So according to the data provided by randomized controlled trials as well as other recent studies, topical solutions fortified with finasteride ia deemed effective for reversing hair loss, as well as preventing further hair loss. The FDA supports these findings.
