Finasteride works by blocking the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). High DHT levels contribute to hair loss. By reducing DHT, finasteride promotes hair regrowth and prevents further hair thinning.
Studies show finasteride is highly effective for treating male pattern baldness. Many men experience significant hair regrowth within six months, with continued improvement over time. However, results vary, and stopping treatment usually leads to hair loss resuming.
Common side effects include decreased libido, erectile dysfunction, and ejaculation problems. These are usually mild and temporary, often resolving upon cessation of treatment. However, a small percentage of men experience persistent side effects. Always discuss potential risks with your doctor before starting finasteride.
Important Note: Finasteride is a prescription medication. Self-medicating is dangerous. A physician should assess your suitability for this treatment and monitor your progress.
Efficacy depends on various factors including age, duration of hair loss, and individual response. Discuss realistic expectations with your doctor. Regular blood tests aren’t typically required for monitoring.
Consider potential interactions with other medications. Inform your doctor about all your medications and supplements before starting finasteride. This ensures safe and effective treatment.
