Keratin Smooth Conditioner is a luxurious, deeply hydrating formula that tames frizz, fluff, and flyaways. True to its name, it’s infused with keratin, the fibrous protein that’s essential for your hair’s strength and structure, making it perfect for dry or damaged hair. The Quat Complex strengthens each strand and helps prevent breakage, while provitamin B5 and shea butter work to moisturize and nourish your hair from the inside out, leaving it smooth, soft, and revitalized.
