K18 Damage Shield Shampoo & Conditioner Set — Color-Safe 2-Pack, pH-Protective & Lightweight

K18 Damage Shield Shampoo and Conditioner Set is a full-size, color-safe daily wash system that gently cleanses, protects, and conditions damaged or color-treated hair without silicones or heavy buildup.

This two-piece kit combines a pH-balanced shampoo and a lightweight protective conditioner formulated to reduce cuticle swelling, soften strands, and shield hair from daily sources of damage like UV exposure and pollution. Built around K18's biotech approach and K18PEPTIDE, the set is designed to fit into a regular routine between deeper repair treatments, delivering manageable, shiny hair after each wash while helping maintain salon color and integrity.

How does this set help protect color-treated hair?

The shampoo's pH-optimized formulation minimizes cuticle opening, which helps retain color molecules and reduce premature fading. The conditioner seals and smooths the cuticle with a ceramide blend and a biotech polysaccharide barrier that deflects environmental stressors.

• pH-protective shampoo decreases cuticle swelling to lock in pigments
• Ceramide-rich conditioner seals hair for up to 3 days of enhanced protection*
• Biotech polysaccharide shields hair from UV and pollution
• Formulated without film-forming silicones or waxes to avoid buildup

Will this set work for fragile or chemically treated hair?

Yes — the gentle cleansing action is designed to avoid over-drying while K18PEPTIDE helps reduce protein loss during routine washing. The conditioner strengthens and detangles without weighing the hair down, making styling and comb-through easier for fragile strands.

• Microbiome-friendly shampoo that cleans without stripping
• Lightweight gel conditioner fortifies and detangles
• Reduces protein loss to support hair structure during daily care
• Safe for repeated use between K18 leave-in treatments

How should I use the Damage Shield Shampoo and Conditioner for best results?

Apply the shampoo to wet hair, focusing on the scalp, then rinse thoroughly; follow with conditioner applied from mid-lengths to ends, leave briefly, and rinse. Use this daily wash routine between K18 Leave-In Molecular Repair Hair Mask sessions to keep hair protected and manageable.

• Massage shampoo into scalp and rinse completely
• Apply conditioner from mid-lengths to ends, detangle, then rinse
• Use as daily maintenance between deeper K18 repair treatments
• Pair with styling products as needed—no silicones in conditioner to interfere

What ingredients make this set low-build-up and salon-quality?

K18 follows a less-is-more philosophy, favoring targeted biotech actives and a clean formulation to deliver salon-level results without unnecessary film-formers. The conditioner avoids silicones and waxes that commonly cause residue, while the shampoo supports scalp and cuticle health with a pH-balanced base and microbiome-friendly choices.

• K18PEPTIDE to help minimize protein loss
• Ceramide blend to seal and strengthen cuticles
• Biotech polysaccharide for environmental shielding
• No film-forming silicones or waxes to prevent buildup

Who is this for: The K18 Damage Shield Shampoo and Conditioner Set is intended for people with color-treated, chemically processed, or otherwise damaged hair who want a daily wash that protects color, reduces frizz, and leaves hair soft and shiny. It suits anyone seeking a lightweight, salon-grade maintenance routine that complements periodic K18 leave-in molecular repair treatments without adding residue.
