Finasteride’s success lies in its ability to block DHT, making it a strong choice for addressing hair loss in men. Studies indicate that around 90% of men experience slowed hair loss, while about 65% experience some regrowth. However, the potential for mild side effects, such as decreased libido or fatigue, exists for a small percentage of users. Despite this, many find the benefits of finasteride outweigh the risks, with significant hair retention and growth over extended use. For many individuals, finasteride offers a long-term solution to hair thinning.
