Complete 2-Step Salon-Size Protection System for Stronger, Healthier Hair

The Joico Defy Damage Duo brings together the 1L Protective Shampoo and 1L Protective Conditioner in one complete daily defence system for all hair types. Designed to shield hair from the three main causes of daily damage — heat styling, UV exposure and environmental pollution — this powerful duo works together to strengthen, protect and visibly improve hair health from the very first use. Reducing hair damage by up to 80%, it is a serious investment in the long-term health and resilience of colour-treated or frequently styled hair. Find it alongside other shampoo and conditioner sets in our full range.

Defy Damage Protective Shampoo 1L

The sulphate-free Defy Damage Protective Shampoo uses Joico's innovative SmartRelease Technology — a liposome delivery system that continuously infuses the hair with Keratin, Rosehip Oil and Arginine during cleansing. Keratin rebuilds and reinforces the hair fibre, Arginine renews hair bonds from within, and Rosehip Oil delivers lasting moisture and protection. Moringa Seed Oil and Vitamin E add an additional antioxidant layer of defence against environmental aggressors and UV damage, while the sulphate-free formula cleanses gently without stripping colour or natural moisture.

Defy Damage Protective Conditioner 1L

The matching Protective Conditioner is a bond-strengthening formula that instantly softens and detangles while reinforcing the hair structure to resist breakage and dullness. SmartRelease Technology continues the delivery of Keratin, Rosehip Oil and Arginine through the conditioning step, ensuring the repair and protection ingredients have maximum contact time with the hair. The result is smoother, shinier and more resilient hair that looks and feels noticeably healthier after every wash.

How to Use the Joico Defy Damage Duo

Apply the Protective Shampoo to wet hair, work into a lather and rinse thoroughly. Follow immediately with the Protective Conditioner from mid-lengths to ends, leave for one to two minutes and rinse. Use daily as a complete protection routine for colour-treated, heat-styled or environmentally exposed hair of all types.
