Finasteride: DHT Blocking Explained

What Is DHT?

Dihydrotestosterone (DHT) is a hormone derived from testosterone. It plays an important role in male development, but later in life, elevated DHT levels may contribute to hair loss in people genetically predisposed to male pattern baldness.

DHT binds to receptors in hair follicles, particularly on the scalp, which may cause those follicles to shrink over time. As a result, the affected hairs may become thinner, shorter, and eventually stop growing altogether.

How Finasteride Works to Reduce DHT

Finasteride belongs to a class of medications known as 5-alpha-reductase inhibitors. This enzyme (5-alpha-reductase) is responsible for converting testosterone into DHT in the body.

By reducing the activity of this enzyme, finasteride may lower DHT levels in the scalp and bloodstream. With less DHT available to bind to hair follicles, the progression of hair thinning may slow or stop in some individuals. In certain cases, patients may even experience regrowth over time.

Clinical studies have shown that finasteride may reduce serum DHT levels by as much as 68%, although results vary between individuals 2.

What to Expect from Treatment

Patients considering finasteride should understand both the potential benefits and risks. While many see positive changes in hair density or slowed hair loss over several months, others may not respond as effectively.

Common considerations include:

• Results may take 3 to 6 months to become noticeable.
  
• Treatment must be continuous to maintain results.
  
• Side effects such as decreased libido, erectile changes, or mood changes may occur in a small percentage of individuals 1.
  
  

A licensed provider can help evaluate whether finasteride may be appropriate based on your goals and medical history.
