What Is the Role of Long-Term Use of Finasteride in Baldness?

The document discussed androgenetic alopecia, which affected approximately 5% of men under 20, nearly 50% of 40-year-old men, and 80% of 70-year-old men. In men, it typically began with a reduction in hair density at the temples and/or a receding frontal hairline or crown baldness, potentially leaving only a ring of hair in extreme cases. Women experienced more diffuse hair thinning, mainly at the crown, while maintaining the frontal hairline. The document likely explored the role of long-term finasteride use in treating this condition, although specific conclusions were not provided in the summary.
