Introduction:
Female pattern hair loss (FPHL) is one of the most common forms of diffuse alopecia in females. Despite the availability of multiple treatment options, FPHL management poses challenges for the dermatologist.
Objectives:
We aimed to compare the efficacy and safety of topical finasteride 1% solution and spironolactone 5% solution to minoxidil 5% solution in the treatment of FPHL clinically and trichoscopically.
Methods:
Forty-five adult female patients diagnosed with FPHL were divided into three groups of 15 each. Group A was treated with topical finasteride 1%, group B used topical spironolactone 5%, and group C was treated with topical minoxidil solution 5 %, all groups were treated for 16 weeks.
Results:
By the end of 16th week, significant improvement on the Sinclair scale was observed in groups A and C, but the difference between the three groups was statistically insignificant. Trichoscopically, hair density significantly increased in groups A and C. There was a significant reduction in the number of patients with yellow dots, peripilar sign, and single hair follicular units (FU) in group A. In group C, a significant reduction in the number of patients with yellow dots and single hair FU was documented. No trichoscopic changes were detected in group B.
Conclusions:
Topical finasteride is as safe and effective as topical minoxidil in FPHL. Both treatments showed greater effectiveness clinically and trichoscopically than topical spironolactone. The use of topical finasteride may be another solution for the treatment of FPHL in minoxidil non-responders or in the presence of intolerable side effects.
