Joico Defy Damage Protective Shield
DESCRIPTION
The Joico Defy Damage Protective Shield is a leave-in treatment spray that guards hair against the daily damage from heat styling, UV exposure, and environmental pollution. This lightweight formula makes hair 4X more resistant to breakage during heat styling while protecting color-treated hair from fading—making it an essential step before reaching for your blow dryer, flat iron, or curling wand.
SmartRelease Technology: Continuous Protection
At the heart of this protective shield is Joico's SmartRelease Technology, a liposome delivery system that continuously releases rosehip oil, arginine, and keratin. Unlike traditional heat protectants that wash away, this system keeps working to repair, strengthen, and protect hair from the cumulative effects of daily styling. The protective lipid in the formula mirrors the kind found in healthy hair, acting as a first line of defense against thermal, chemical, and UV damage.
Key Ingredients That Work
Moringa seed oil bathes hair in antioxidants, vitamins A and E, zinc, and silica—ingredients fundamental to creating strong, damage-resistant hair with boosted shine and softness. Arginine helps strengthen hair bonds and encourage bond renewal. The result? Hair that's visibly shinier, softer, and healthier-looking from the very first application.
What Customers Say
Stylists and everyday users alike recommend this product for its versatility and results. It doesn't weigh hair down, works on all hair types from fine to coarse, and a little goes a long way—making the 3.38 oz bottle last for months. Users appreciate that it smooths frizz, improves manageability, and leaves hair smelling great without any stiff or sticky residue. Apply a small amount to clean, damp hair, comb through for even distribution, and style as usual for all-day protection that you can see and feel.
