The Joico Defy Damage Protective Shield is a leave-in treatment designed to guard against the effects of daily heat styling, UV exposure and environmental pollution that can lead to dull, lacklustre locks.

Building a defence against daily aggressors, the pre-styling formula helps to prevent damage and colour fading, working tirelessly to maintain vibrant, healthy-looking locks. Hair is 4x more resistant* to breakage during heat styling and is left feeling soft, shiny and fortified.

*Against combing breakage on clean, damaged hair.
