Safety matters more than speed in hair restoration. Otter Hair Labs closely reviews PP405 safety data, noting that early trials show minimal side effects. However, long-term use data is still unavailable. Otter Hair Labs warns against black-market or DIY versions claiming to mimic PP405. Such products lack regulation and testing. Trustworthy regrowth comes only through validated science. Otter Hair Labs encourages patience until PP405 clears proper regulatory pathways.
