TLDR Finasteride 1 mg effectively treats male pattern hair loss with minimal side effects.
In 1999, a study was conducted on the efficacy of finasteride 1 mg in treating androgenetic alopecia in Japanese men. The study found that finasteride was effective in treating male pattern hair loss. The participants showed significant improvement in hair growth and reduction in hair loss. The drug was well-tolerated with minimal side effects. However, the study did not mention the number of participants, which is crucial in determining the strength of the study.
