Kiehl's Amino Acid Shampoo 1 L Refill — Coconut Oil Clarifying, Strengthens Hair

Kiehl's Amino Acid Shampoo is a gentle daily cleanser with amino acids and coconut oil that cleans hair, adds body, and helps reduce breakage while preserving moisture.

This 33.8 fl oz (1 L) refill of Kiehl's Amino Acid Shampoo is formulated to clarify and refresh hair without stripping natural hydration. The lightweight, creamy formula foams easily to lift away dirt, excess oil, and styling residue; amino acids, coconut oil, and wheat protein work together to support softness, manageability, and visible shine. Paraben-free and crafted for use on all hair types, the refill format makes it economical and convenient for regular use.

How does this shampoo clean without leaving hair dry or heavy?

The formulation uses mild surfactants complemented by amino acids that help cleanse while preserving hair’s moisture balance. Coconut oil and wheat protein add nourishing lipids and conditioning support so hair feels soft rather than stripped. Because the texture is lightweight and creamy, it spreads easily and rinses clean without residue.

• Mild, low-irritation surfactants for effective cleansing
• Amino acids to support moisture retention and hair structure
• Coconut oil delivers fatty acids for conditioning without weight
• Wheat protein helps improve manageability and smoothness

Will this help reduce breakage and make hair look fuller?

The shampoo targets surface cleansing and internal hydration to reduce friction and brittleness that can cause breakage. By improving softness and flexibility, hair is less prone to snapping during styling or detangling, which can give the appearance of greater volume and health. Regular use contributes to fuller-looking, more resilient strands.

• Strength-supporting amino acids fortify hair fibers
• Hydrating coconut oil adds slip for gentler detangling
• Wheat protein conditions to minimize breakage during styling
• Creates body and lift without adding heavy deposits

How should I use the 1 L refill to get best results?

Pour a measured amount into your regular shampoo bottle, or dispense directly into your palm if you prefer. Apply to thoroughly wet hair, massage to create a lather from roots to ends, then rinse completely. For optimal results follow with a conditioner or the matching Kiehl’s Amino Acid conditioner.

• Refill into pump bottle for convenient daily use
• Massage gently—focus on scalp and mid-lengths
• Rinse thoroughly to prevent build-up
• Pair with Kiehl’s Amino Acid conditioner for extra softness

Who is this for: The Kiehl's Amino Acid Shampoo 1 L refill suits anyone seeking a daily, paraben-free cleanser that balances gentle yet effective cleansing with conditioning benefits.

If you want a lightweight shampoo that supports strength, adds body, and leaves hair soft and shiny without heaviness, this refill offers an economical and eco-aware option.
