If you’re dealing with male pattern hair loss, chances are you’ve heard of Finasteride. It’s one of the most widely recognised treatments available—and for good reason. But while it’s often recommended, one question keeps cropping up: can Finasteride actually grow hair back?

 

Let’s dive into the science - and explore why combining Finasteride with other treatments like Minoxidil often delivers the best results.

 

So, Can Finasteride Regrow Hair?

 

The short answer? Yes—it can.

 

Finasteride is one of only two medications clinically proven to treat male pattern hair loss (the other being Minoxidil). A study published in the Journal of the American Academy of Dermatology found that men taking Finasteride experienced an average 16% increase in hair count over two years. That’s not just maintaining what you’ve got—that’s genuine regrowth.

 

Another long-term study from Japan followed men taking Finasteride for 10 years. The findings?

 

  • 99% of participants experienced no further hair loss.
  • Over 91% saw visible improvements in hair density and coverage.

 

While individual results can vary, the evidence is clear: Finasteride doesn’t just slow hair loss - it can reverse it for many men.

 

How Does Finasteride Work?

 

Finasteride works by targeting dihydrotestosterone (DHT) - the hormone responsible for shrinking hair follicles and halting healthy hair production.

 

It blocks DHT from binding to receptors in the follicles, effectively stopping the process known as miniaturisation. Left unchecked, this process causes follicles to weaken, shrink, and eventually stop producing hair altogether.

 

Taken as a daily tablet, Finasteride is a long-term treatment - it only works for as long as you continue to take it. Fortunately, it’s safe for ongoing use and forms the backbone of many successful hair loss treatment plans.

 

Why Pair It with Minoxidil?

 

While Finasteride tackles the hormone causing hair loss, Minoxidil works in a different way. As a vasodilator, it improves blood flow and increases oxygen and nutrient delivery to the scalp - helping to stimulate regrowth and support healthier, thicker hair.

 

That’s why combining the two is often recommended. It’s a dual-action approach. 

 

At Sons, we offer several options that combine both treatments:

 

  • Combination Spray – A once-daily solution that includes both Finasteride and Minoxidil in one easy application.
  • Ultimate Plan – Our most comprehensive plan, combining Finasteride, Minoxidil, a Hair Growth Complex (with Biotin), and a DHT-blocking shampoo for all-round support.
  • Core Capsule Plan – Includes oral Minoxidil as an alternative to the topical version—perfect for men who prefer not to apply a solution daily.

 

Recap: Can Finasteride Regrow Hair?

 

Yes- Finasteride can regrow hair in up to 60% of men, according to clinical studies. Even in cases where regrowth is limited, it can still perform the crucial role of stopping further loss by targeting DHT, the main driver of male pattern hair loss.

 

If you’re serious about protecting and restoring your hair, combining Finasteride with Minoxidil gives you the best chance of success.
