PP405 is a potential hair loss treatment that may activate dormant hair follicles, but there are concerns about its effectiveness, cost, and side effects. Users discuss treatments like minoxidil, finasteride, and RU58841, expressing skepticism about PP405's long-term success and accessibility.
Oral minoxidil is temporarily unavailable in the USA due to import laws, prompting consideration of topical minoxidil as an alternative. Tariffs and political policies affect the availability and cost of hair loss treatments.
