It’s not only an invisible shield that safeguards your hair against the rigors of heat styling(up to 450 degrees); but we consider it a tool by itself that finishes the smoothing process to perfection.

The hydrolized keratin springs into action when it detects anything from a heat tool to actual sunlight–forms a literal shield of protection against frizzing, fading, and environmental damage. Joico’s formaldehyde-free KeraShield Complex (with Keratin, Brazil Nut Oil, and Tucuma Butter) strengthens the hair and keeps unruly hair at bay for up to 72 hours.
