    TLDR Finasteride significantly improves hair growth but may cause sexual side effects.
    The study aimed to determine the effects of finasteride (1 mg) on scalp hair growth in men aged 18 to 60 years with male pattern hair loss. The study found that treatment with finasteride resulted in statistically significant hair growth versus placebo in all scalp regions affected by male pattern hair loss. However, a slightly higher incidence of drug-related sexual adverse experiences was reported in the finasteride group than in the placebo group, irrespective of age. Overall, the study demonstrated the safety and efficacy of finasteride for the treatment of male pattern hair loss in men aged 18 to 60 years.
