Polyquaternium 7 Hair Conditioner - Professional Salon-Grade Detangling & Smoothing Treatment for Frizzy, Dry, and Damaged Hair - Perfect for Daily Use, Post-Color Care, and Heat Styling Protection

Polyquaternium 7 is a water-based conditioning agent used in shampoos, conditioners, and leave-in hair products as well as bath and shower gels and body wash.

Designed for use in surfactant based products, this liquid dries to form a protective barrier and seals in moisture, creates a silky soft feel, and prevents the negative effects of humidity on hair. When used in leave-in applications it provides good slip for detangling and imparts softness and shine.
