Strengthen, Smooth & Shield Hair from Daily Damage

Meet the K18 DAMAGE SHIELD Protective Conditioner — a lightweight, color-safe, and pH-balanced conditioner designed to protect and strengthen hair after every wash. Created by K18 Biomimetic Hairscience, this sulfate-free, silicone-free, vegan formula hydrates and defends hair from damage caused by heat styling, UV exposure, and environmental stress.

Repair and Protect with Every Use

Powered by the patented K18 Peptide™, this biomimetic conditioner works at the molecular level to restore softness, shine, and elasticity. Unlike heavy traditional conditioners that simply coat the surface, the K18 formula rebuilds the inner structure of the hair while creating a protective shield that locks in moisture and prevents future breakage.

Key Benefits

• Strengthens and protects hair from heat, UV, and mechanical damage

• Reduces frizz and enhances smoothness and shine

• Restores softness and manageability without weighing hair down

• Maintains the hair’s natural pH balance for lasting health

• Safe for color-treated, bleached, or chemically processed hair

• Vegan, cruelty-free, sulfate-free, silicone-free, and paraben-free

How to Use

1. After shampooing with K18 DAMAGE SHIELD pH Protective Shampoo, apply the conditioner evenly from mid-lengths to ends.

2. Leave on for 1–2 minutes to allow nutrients to absorb.

3. Rinse thoroughly.

4. For enhanced repair, follow with the K18 Leave-In Molecular Repair Hair Mask.

The Science Behind K18 Biomimetic Haircare

Every K18 formula is powered by K18 Peptide™ — a patented molecular technology that reconnects broken keratin chains inside the hair fiber. This innovation reverses damage from bleach, color, and heat while maintaining pH balance and strengthening hair from within. The DAMAGE SHIELD Protective Conditioner works as the perfect follow-up to the shampoo, sealing in hydration and providing a barrier against everyday stressors.
