The Inside-Out Set

A three-piece routine that pairs our foundational daily supplement with a pigment-preserving, color-safe shampoo and lightweight conditioner. Not Today, Grey feeds follicles from within with a physician-formulated blend of vitamins, minerals, and antioxidants that help defend natural pigment. An easy daily ritual that’s flavorless, gentle, and with no aftertaste. Wash Shampoo delivers our patented Mela-9® Complex (antioxidants + a clinically proven peptide) to the scalp in a sulfate-free, creamy lather that lifts buildup without stripping. Smooth Conditioner finishes with lightweight, strand-strengthening hydration that reduces breakage and locks in moisture for slip, shine, and an air-dry that doesn’t fall flat. Use daily and consistently. Most see visible improvements in 3–6 months, especially in the early stages of greying. Color-safe, dermatologist-tested, and hypoallergenic.
