Proscalpin 1mg contains finasteride at the 1mg strength commonly used in medical treatment of androgen-related male pattern hair loss. Finasteride inhibits 5-alpha-reductase, thereby lowering the conversion of testosterone into DHT. This mechanism can help slow the hormonal process associated with progressive scalp hair miniaturization in susceptible men.

Treatment benefits generally depend on continued use rather than isolated doses, and discontinuation may lead to loss of maintained benefit over time. Because finasteride can produce systemic hormonal effects, it should be used according to professional advice. Users should also report relevant symptoms or concerns rather than altering their regimen independently.
