    TLDR Finasteride is more effective for hair loss in people with body hair.
    This pilot study in Japan examined the effectiveness of oral finasteride for treating androgenetic alopecia (AGA) in 37 patients, divided into two groups based on body hair presence. Finasteride showed an overall efficacy of 59.5%, with significantly higher effectiveness in the pileous group (88.9%) compared to the non-pileous group (31.6%). The findings suggested that finasteride was more effective in AGA patients with body hair, indicating a stronger androgen influence in these individuals. The study noted no hair growth effects outside the scalp and no serious adverse events, but it was limited by its small size and subjective assessments.

The patient and others in the conversation debated this advice, discussing the relationship between finasteride, prostate cancer, and hair loss, and considering alternatives like topical finasteride.

      The user has been using Minoxidil for over 10 years, started Finasteride 8 months ago, and is happy with the hair recovery results; they also use a 1.5mm dermaroller weekly and a 0.5mm occasionally. Some believe starting with Minoxidil is less effective than addressing DHT directly, and there's curiosity about whether dermarolling aids absorption.
