How effective is finasteride?
Finasteride is not a miracle treatment, but it works reasonably well for many people. Results tend to be slow, and it appears to be much better at retaining than regrowing hair. But as treatments go, it’s fairly effective. Recent longer term results indicate that it continues to work well for responders (i.e., the majority of users) a few years into treatment. Like all treatments discussed here, it is typically best used as part of a multifaceted program.
