Separate route comparisons from combination comparisons
The oral minoxidil-finasteride product lists minoxidil 1 mg and finasteride 1.25 mg. The topical combination lists minoxidil 6% and finasteride 0.1%. Moving between them changes the route and the way concentration is expressed. It also changes the complete administered formulation.
The 2024 oral-versus-topical minoxidil trial tested 5 mg orally once daily against topical 5% twice daily for twenty-four weeks in men. Its overall result did not demonstrate superiority for oral treatment. That result belongs to those regimens; it cannot be assigned directly to either catalog combination.

A similar result is not proof of equivalence
The 2023 publication compared 1 mg oral minoxidil with a 5% topical solution over six months in sixty-five patients. Between-group differences were not statistically significant. The trial’s design and precision determine what that comparison can establish. A nonsignificant difference should not be rewritten as proof that all oral and topical regimens are equivalent.
The 2021 cohort of 1,404 patients addressed reported adverse events during low-dose oral treatment. Its retrospective design and lack of a randomized control group make it a different source from the two route-comparison trials.

Keep the outcome attached to the population
The 1998 finasteride trials tested 1 mg oral treatment in men with androgenetic alopecia. Scalp hair counts, investigator assessments and photographs provided several views of the response. They should remain identified rather than being condensed into an unexplained success percentage.
Across the catalog, minoxidil plus spironolactone changes the companion ingredient from finasteride. Research on the individual ingredients can inform that comparison, while a result for the complete combination requires a study of that intervention.
