Kirkland Signature Professional Moisture Shampoo Conditioner 33.8 Fl Oz Pair

Kirkland Signature Professional delivers sustained hydration and color retention in a dual-pack of two 33.8-fl-ounce bottles.

Botanical Hydration and Gentle Surfactant System

The paired shampoo and conditioner combine Argania Spinosa Kernel Oil, Aloe Barbadensis Leaf Extract, Cucumis Sativus Fruit Extract, Lycium Barbarum Fruit Extract, Punica Granatum Extract, and Malus Domestica Fruit Cell Culture Extract to replenish moisture lost through heat styling or chemical processing. Cleaning relies on a sulfate-free architecture featuring Cocamidopropyl Hydroxysultaine, Sodium Cocoyl Isethionate, Potassium Cocoyl Glycinate, and Sodium Lauroyl Methyl Isethionate. This combination dissolves surface debris and excess sebum while maintaining the hair cuticle, resulting in smoother texture and reduced tangles post-wash.

Color Lock and Formulation Transparency

Manufactured in the United States by Costco Wholesale Corporation, this collection carries a dye-free specification that protects dyed or bleached hair from artificial colorant transfer and oxidation. The formula omits phosphates, parabens, and synthetic color dyes, aligning with routine maintenance cycles for sensitive scalps and eco-conscious rinses. Each vessel contains exactly one liter of water-aqua-eau-driven solution engineered for extended shelf stability.

• Two 33.8 fl oz (1 L) containers included
• Purified water base with targeted lipid-restoring botanicals
• Engineered to prevent color fading and dullness
• Explicitly free of added phosphates, parabens, and artificial dyes

Choose this set when you need measurable ingredient transparency, reliable slip for detangling, and bulk volume that replaces frequent small-bottle replacements at professional retailers.
