Comparison of Topical Finasteride and Oral Finasteride in the Treatment of Androgenic Alopecia: A Systematic Review and Meta-Analysis

This study found that topical finasteride significantly increased hair count in men with androgenetic alopecia compared to placebo while maintaining similar efficacy to oral finasteride but with lower systemic exposure and a reduced impact on serum DHT levels, potentially minimizing sexual side effects.

This study found that applying a novel 0.25% finasteride solution to the scalp can effectively reduce scalp DHT levels in men with androgenetic alopecia, potentially reducing systemic side-effects.

This study found that both topical and oral finasteride significantly reduced plasma DHT after one week, with lower finasteride plasma exposure for the topical formulation.

This article reviews existing treatments for male-pattern hair loss, noting that while they can slow progression, they generally achieve only partial hair regrowth.

This study found that both topical and oral finasteride had similar therapeutic effects in treating male androgenic alopecia, with no significant differences in hair thickness, counts, or bald area size.

This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.
