To achieve this, four sheets of paper will be prepared - two with the name of the intervention and two with the name of the control. These paper sheets will be pooled and placed in a container. Patients will be selected one at a time without replacement, and for each patient, a paper sheet will be randomly drawn from the container. After each draw, the paper sheets will be returned to the container, and the process will be repeated until the desired sample size is reached, Blinding description: The randomization process will be conducted by a separate individual from the one who examines the patients, ensuring that the examining person remains unaware of the intervention. Therefore, the trial will be conducted as a single-blind study. 2-3 Androgenic alopecia. Intervention 1: Intervention group: Topical minoxidil 5% plus topical finasteride 0.25% on alopecia location twice daily for 4 months. Intervention 2: Control group: Topical minoxidil 5% on alopecia location twice daily for 4 months. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is It depends on the situation and the results of the study as well as the approval of the financial supporting organization.
