Protective Shampoo is a sulfate-free, everyday cleanser from Joico's Defy Damage line, built around a liposome delivery system the brand calls SmartRelease Technology. Rather than a single blended surfactant wash, it continuously releases Rosehip Oil, Arginine, and hydrolyzed Keratin onto hair as it cleanses, aiming to reinforce hair's own protective lipid layer instead of just stripping it during washing.
- Free of sodium lauryl/laureth sulfate — cleanses with milder surfactants (Sodium C14-16 Olefin Sulfonate, Cocamidopropyl Betaine, Lauryl Glucoside, among others)
- Formulated to help color-treated hair resist fading rather than stripping color with each wash
- Contains Moringa Oleifera Seed Oil, a source of antioxidants and vitamins A and E
- Part of a coordinated system (with the matching conditioner and Protective Shield) built around a shared set of anti-damage ingredients
It's a rinse-off product, so its role is gentle, non-stripping cleansing that sets up the leave-in steps of the routine — it is not a substitute for a leave-in heat or environmental protectant. Gentle enough for daily use, it works into a normal wash routine without changing how hair is shampooed day to day.
