Finasteride is one of the most commonly prescribed medications in the UK for male pattern baldness (androgenetic alopecia) and benign prostatic hyperplasia (BPH). In 2025, its use has continued to grow—especially among younger men looking to address hair thinning early and discreetly.

If you're considering using finasteride for hair loss treatment, it's important to know where you can buy it safely and affordably. This article outlines what finasteride is, how it works, and where you can buy it in the UK at a reasonable price.

What is Finasteride?

Finasteride is a 5-alpha-reductase inhibitor that works by reducing levels of dihydrotestosterone (DHT), a hormone that causes hair follicles to shrink and eventually stop producing hair in genetically predisposed individuals.

For hair loss, the typical dose is 1 mg per day, marketed in some countries as Propecia.
