Kiehl's Amino Acid Conditioner 1 L Refill — Lightweight Strengthening & Moisturizing for All Hair Types

This one-liter refill delivers the same creamy, easy-to-distribute formula developed to smooth and nourish hair after shampooing. Designed for everyday use, the conditioner targets softness, detangling, and shine while maintaining a lightweight finish suitable for all hair textures. Because it combines amino acids with plant-derived oils, it supports surface conditioning and slips through strands for fast rinsing and minimal residue.

How does this conditioner strengthen hair?

The formula uses amino acids—small building blocks that help reinforce the hair fiber’s surface—paired with nourishing oils to reduce breakage from combing and styling. Regular use helps hair feel firmer and less prone to snap during daily handling without adding heavy oils that cause limpness.

• Amino acids help condition and support cuticle alignment.
• Jojoba oil softens fiber for smoother detangling.
• Coconut oil supplies fatty acids for surface nourishment.

Will this weigh my hair down or make it greasy?

No—this conditioner is formulated with a lightweight, creamy texture that spreads easily and rinses clean. It provides moisture and slip without leaving heavy buildup, making it appropriate for fine, medium, or thick hair when used as directed.

• Light, non-greasy cream base for easy distribution.
• Rinses thoroughly to avoid residue and flatness.
• Suitable for daily use on most hair types.

How should I use the 1 L refill for best results?

Use after shampooing: apply to clean, wet hair, focusing on mid-lengths and ends, leave on for about two minutes, then rinse. For consistent improvement in manageability and shine, pair it with Kiehl’s Amino Acid Shampoo and incorporate into your regular hair routine.

• Apply to towel-dried hair after shampooing.
• Leave on ~2 minutes before rinsing thoroughly.
• Use with Kiehl’s Amino Acid Shampoo for optimal results.

What ingredients provide moisture and gloss?

Two plant-derived oils—jojoba and coconut—work alongside amino acids to deliver moisturizing fatty acids and softening benefits. Together they smooth the hair surface for enhanced shine while the lightweight base prevents a greasy feel.

• Coconut oil supplies nourishing fatty acids for hydration.
• Jojoba oil helps smooth and condition the hair fiber.
• Amino acids assist surface conditioning and manageability.
