What is Finasteride? Oral finasteride (sold under the brand name Propecia®) is FDA-approved for the treatment of hair loss, but for some people it can cause sexual side effects like erectile dysfunction and reduced ejaculation. To reduce those systemic side effects, some may opt for a topical finasteride treatment instead. But whether applied via a topical application like a spray or gel or taken orally, finasteride works to prevent male pattern baldness in the same way. Male pattern hair loss is caused by enzymes that are responsible for the conversion of testosterone into the male sex hormone dihydrotestosterone (DHT), a major androgen. High DHT levels cause the hair follicles — the tiny organs throughout your scalp from which your hair grows — to shrink and reduce, which leads to baldness. Finasteride is part of a group of medications called 5-alpha reductase inhibitors, which prevent the conversion of testosterone to dihydrotestosterone. Oral finasteride is absorbed systemically, which means every part of your body from your skin to your liver absorbs it. Topical finasteride, on the other hand, provides localized treatment and is mainly absorbed through your scalp (assuming that’s where you apply it). Topical finasteride isn’t approved for use by the FDA, but some combination hair loss products (those that include multiple kinds of medication) may contain it in very low concentrations according to a systematic review published in the journal Natural Products and Bioprospecting.
