The Lock-In Thicker Hair 6-Month Supply includes three full-size (60ml) bottles of our Lock Drops Anti-Shedding Scalp & Hair Serum — giving you the consistency needed to see real, lasting results. Powered by Epidermal Growth Factors and the HG3 complex featuring 3% Procapil™, 3% Redensyl®, and a bio-botanical blend, this once-daily serum helps reduce shedding, anchor strands at the root, and support visibly fuller, thicker-looking hair over time. Because when it comes to growth, consistency is everything.
