Kiehl's Amino Acid Conditioner — Lightweight Strengthening 16.9 fl oz for Manageable, Shiny Hair

Kiehl's Amino Acid Conditioner is a lightweight daily treatment that strengthens and hydrates hair using amino acids, jojoba and coconut oil for improved manageability and natural-looking shine.

This creamy, mild conditioner is formulated to work with all hair types, delivering moisture and slip without weighing strands down. Designed to be used after shampooing, the formula helps detangle, soften, and leave hair feeling resilient and easy to style. With a balance of conditioning oils and amino acids, it targets texture, smoothness and overall surface appearance while remaining gentle enough for everyday use.

How does this conditioner make hair feel softer without heaviness?

The blend of amino acids and lightweight oils coats the hair shaft to smooth cuticles and improve slip, so hair detangles and moves more freely. Coconut oil supplies nourishing fatty acids while jojoba oil mimics natural scalp lipids to add softness without greasy residue. Results are visible as improved manageability and a polished finish rather than weighed-down strands.

• Amino acids: strengthen and smooth the hair fiber
• Coconut oil: lightweight nourishment and shine
• Jojoba oil: softens without oiliness
• Creamy texture: easy rinse-out and no buildup

When should I use it and how long should I leave it on?

Apply this conditioner after shampooing while hair is wet; its quick-acting formula works in minutes. For standard conditioning, leave it on for around two minutes then rinse thoroughly. For extra softness on dry or textured hair, you can extend the leave-in time slightly or combine with a weekly deep treatment.

• Use daily or as needed after shampooing
• Standard leave-on: ~2 minutes
• Rinse well to avoid residue
• Pair with Kiehl's Amino Acid Shampoo for best synergy

Will it work for all hair types, including colored or fine hair?

The formula is gentle and balanced for a wide range of textures—from fine to thick, straight to curly—and is mild enough for color-treated hair. Its lightweight nature helps fine hair stay bouncy while providing enough moisture for drier textures. As with any product, perform a patch or strand test if you have specific sensitivities or recent chemical treatments.

• Suitable for fine, medium, and coarse hair
• Color-safe friendliness when used as directed
• Non-heavy formulation for lifty roots
• Works well with heat-styling routines
