Finasteride works by inhibiting the enzyme 5-alpha-reductase, which converts testosterone to dihydrotestosterone (DHT). High DHT levels contribute significantly to hair loss in men. By reducing DHT, Finasteride slows hair loss and, in some cases, promotes hair regrowth.
Studies show Finasteride’s efficacy varies. Approximately 60-80% of men experience improvement in hair loss, with noticeable regrowth in a considerable number. Response depends on factors including age, duration of hair loss, and individual genetics. Optimal results often require consistent daily use for at least six months.
Common side effects are generally mild and temporary, affecting less than 2% of users. These include decreased libido, erectile dysfunction, and ejaculation disorders. Serious side effects are rare. Consult your doctor immediately if you experience persistent or concerning symptoms. Regular monitoring by a healthcare professional is recommended.
Before starting Finasteride, discuss potential risks and benefits with your doctor. They can assess your suitability and advise on appropriate usage. Discontinuing Finasteride may lead to a return of hair loss. Remember, individual results vary.
