Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.
The conversation discusses the need for a localized 5-alpha reductase inhibitor that only affects the scalp without systemic side effects, similar to pyrilutamide's approach. Current treatments like topical liposomal finasteride and dutasteride are mentioned, but concerns about their systemic effects and lack of research are highlighted.
Oral dutasteride is the most effective for hair regrowth, followed by oral finasteride and minoxidil. Topical finasteride combined with minoxidil is recommended for those avoiding systemic DHT reduction.
A user's experience with using 5AR inhibitors (Finasteride and Dutasteride) in combination with Minoxidil foam and microneedling, which resulted in substantial improvements to their crown density and hairline, despite high systemic levels of testosterone and dihydrotestosterone.
Breezula shows promise in stabilizing hair loss and potentially promoting regrowth at the one-year mark, offering hope for those who can't tolerate 5AR inhibitors. Its local targeting of androgen receptors could be a significant advancement if it avoids systemic side effects.
