Kiehl's Amino Acid Shampoo — Coconut Oil Clarifying 33.8 fl oz (1 L) Refill, Paraben-Free, Strengthening

Kiehl's Amino Acid Shampoo is a gentle, daily-use cleanser formulated with amino acids and coconut oil to clarify hair, add body, and help reduce breakage while preserving moisture.

This 33.8 fl oz (1 L) refill bottle delivers a lightweight, creamy shampoo designed for everyday use on all hair types. The formula blends amino acids for mild cleansing and moisture retention, coconut oil for fatty-acid nourishment, and wheat protein to condition strands. It rinses clean without weighing hair down, leaving hair feeling soft, shiny and fuller in appearance.

How does this shampoo clean without drying my hair out?

The formulation uses gentle amino-acid based surfactants instead of harsh detergents, so it lifts oil and buildup while helping the hair retain water. Coconut oil and wheat protein are included to replenish lipids and condition the fiber during the wash.

• Amino acids: mild cleansing agents that support moisture balance.
• Coconut oil: supplies fatty acids to help nourish and smooth the strand cuticle.
• Wheat protein: adds conditioning and temporary strengthening for a softer feel.

Will it work for my hair type—fine, thick, or color-treated?

The shampoo is formulated to be suitable for all hair types because of its lightweight texture and non-greasy finish. It adds volume and body to fine hair without heaviness, while providing hydration and conditioning for medium to thick hair; it is also paraben-free for everyday use.

• Fine hair: creates lift and fuller appearance without residue.
• Thick or coarser hair: moisturizes and smooths fibers for manageability.
• Color-treated hair: gentle cleansing helps preserve vibrancy when used as part of a proper routine.

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

Dispense an appropriate amount onto wet hair, massage into a lather from roots to ends, then rinse thoroughly. For optimal performance, follow with a compatible conditioner or the Kiehl's Amino Acid conditioner to lock in moisture and reduce tangles.

• Wet hair first to help even distribution and lather.
• Massage gently to stimulate scalp circulation and dissolve buildup.
• Rinse completely and finish with conditioner for added softness.

Is this product free of any harsh ingredients I should avoid?

The shampoo is paraben-free and formulated with mild surfactants and conditioning agents rather than sulfates known to strip moisture. While it is gentle, always check the ingredient list if you have specific sensitivities or allergies.

• Paraben-free: avoids common parabens used as preservatives.
• Mild surfactants: designed for everyday cleansing without excess dryness.
• Contains coconut oil and wheat protein: natural-derived conditioning components.

Who is this for? This 1 L refill is ideal for anyone who wants a gentle, everyday shampoo that clarifies and conditions without weight—people looking to add body to fine hair, maintain softness in medium-to-thick hair, or simplify routines with a single, multi-use cleanser. It suits households that prefer larger refill sizes for longer-lasting supply, and those who favor formulas focused on moisture balance and manageable results.
