@engineermeg: Replying to @Sara Tobi $32 for five clinically studied actives when most $100+ serums only bother including one or two of 😱 redensyl, procapil, capixyl, baicapil, anagain, all in one bottle. but did it do anything? mass balance 101: accumulation = in - out + generation. aminexil (in the l’oréal serum), reduces the "out" by stopping collagen around the follicle from hardening and keeps what you have anchored ✅ this one increases generation and works to make new hair sprout 🌱 follow for more updates and engineer-tested products 🧪 #hairgrowthserum #chemicalengineering #theordinarymultipeptideserum #scalphealth #engineeringgirls
