Finasteride  in Gender-Affirming Care: An overview


Gender-affirming care encompasses various medical interventions aimed at aligning an individual’s physical characteristics with their gender identity. Among these interventions, finasteride, a medication primarily used to treat benign prostatic hyperplasia (BPH) and androgenetic alopecia (male-pattern baldness), has emerged as a valuable tool in the journey of transgender individuals seeking hormonal transition.

Finasteride and Testosterone Blockade

For transgender women (assigned male at birth) undergoing hormone therapy, the suppression of testosterone is a crucial step in achieving feminization. While estrogen therapy is typically the cornerstone of this process, adjunctive medications like finasteride can further inhibit the effects of testosterone.

Finasteride works by blocking the conversion of testosterone to dihydrotestosterone (DHT), a more potent androgen. By reducing DHT levels, finasteride can help mitigate androgen-related effects such as facial hair growth and scalp hair loss, promoting a more feminine appearance and enhancing gender affirmation.

Hair Restoration and Feminization

In addition to its role in hormone therapy, finasteride offers benefits in addressing androgenetic alopecia, commonly experienced by transgender women. Hair loss can be distressing and may hinder the process of gender transition. Finasteride’s ability to promote hair regrowth and prevent further loss can significantly contribute to the feminization process, bolstering self-confidence and well-being.

Dosage and Administration

The dosage of finasteride in gender-affirming care typically ranges from 1 mg to 5 mg per day, depending on the specific indication and individual response. It is usually taken orally and can be administered alongside other hormone therapy medications, under the guidance of a healthcare provider specializing in transgender care.


Finasteride represents a valuable addition to the toolkit of medications used in gender-affirming care for transgender women. Its ability to block testosterone conversion and promote hair restoration contributes to the process of feminization, supporting individuals in achieving their desired gender identity and expression. As part of a comprehensive treatment approach, finasteride empowers transgender individuals to embrace their authentic selves, fostering resilience, confidence, and overall well-being.
