Minoxidil may inhibit androgen receptors and affect hormonal pathways, potentially explaining its effectiveness in treating androgenetic alopecia (AGA). Users discuss its varying effectiveness on scalp versus facial hair and note fewer side effects with topical use compared to oral.
RU58841, a potential hair loss treatment, was not commercialized due to marketability issues and lack of long-term safety data. Concerns about its formulation and delivery methods further complicate its use.
RU58841 is used topically to prevent hair loss by blocking DHT, with suggestions to drink grapefruit juice, take breaks, avoid microneedling, and use lower concentrations to reduce side effects. Users discuss applying it at night to minimize systemic absorption.
Dutasteride may inhibit androgen receptors in addition to reducing DHT, potentially explaining its effectiveness over finasteride for hair loss. Concerns about its impact on muscle growth are debated, with some suggesting no significant effects.
