The Role of Topical Finasteride in Hair Loss Management: Current Evidence and Future Perspectives

Hair loss (HL), scientifically known as alopecia, is a prevalent condition affecting individuals globally.

While oral FIN has been widely explored, it entails undesirable side effects and varying effectiveness.
