What is Finasteride and how does it work for hair loss?

Finasteride is a prescription medication widely used to treat male-pattern baldness by inhibiting the enzyme 5-alpha-reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), the hormone responsible for shrinking hair follicles in genetically sensitive individuals. By reducing DHT levels, finasteride slows hair thinning and helps maintain existing hair. Many men also experience regrowth in areas where follicles are still active. At Evolved Hair Restoration Clinic, we explain how finasteride works, what results you can expect and how to use it safely within a structured plan. Our team carefully evaluates whether finasteride is suitable for you based on your age, medical background and hair loss stage. For many clients, finasteride serves as a cornerstone treatment that protects their long-term results—whether used alone or alongside other therapies.
