A few of recently published medical studies from Japan and Italy support the previously published lower incidence of side-effects and the long term effectiveness of Propecia. The Japanese study followed 3177 men for 3 years and the Italian study followed 113 men for 10 years. In both studies, over 80% of patients showed long-term growth and stability on the medication without any significant side-effects.
In summary, Propecia remains a very effective and safe treatment for male pattern hair loss. Propecia has demonstrated clear superiority compared to other treatments for hair loss and side effects can be significantly reduced with adjusted or lower doses.
