The K18 Damage Shield pH Protective Shampoo is a professional-grade, color-safe cleanser engineered to effectively remove dirt, oil, and impurities while actively safeguarding hair health and strength. Featuring a highly advanced, pH-optimized and microbiome-friendly formula, this gentle shampoo maintains the scalp's natural ecosystem and prevents the hair cuticle from swelling excessively during washing. Infused with the patented K18PEPTIDE™, it works to reinforce the hair's structural integrity, dramatically reduce frizz, and lock in color vibrancy without over-drying or stripping moisture.

Key Benefits

• K18PEPTIDE™ Fortification: Delivers targeted peptide biotechnology to strengthen the hair fiber during the cleansing process, enhancing overall resilience.

• pH-Optimized Engineering: Specifically formulated with a low-pH baseline to keep the hair cuticle closed and flat, minimizing frizz, maintaining smoothness, and preserving hair color.

• Gentle, Effective Cleansing: Efficiently lifts away product buildup, excess sebum, and environmental impurities without pulling out natural hydration or leaving the hair feeling brittle.

• Microbiome-Friendly Design: Respects and protects the delicate ecosystem of the scalp, preventing irritation and ensuring an optimal environment for healthy hair development.

• Daily Defending Care: Safe and gentle enough to be used every single time you wash, providing an excellent foundation for any hair repair or styling regimen.

How to Use

1. Apply: Thoroughly wet your hair. Dispense a moderate amount of DAMAGE SHIELD pH Protective Shampoo and focus the application on your scalp and roots.

2. Massage: Work the shampoo into a rich, gentle lather using your fingertips to stimulate the scalp and lift away impurities.

3. Rinse: Rinse completely with warm water, ensuring no residue is left behind.

4. Repeat: If you have heavy product buildup or thick hair, repeat the washing process a second time if necessary.

5. Follow Up: For maximum protection against daily damage, follow directly with the K18 DAMAGE SHIELD pH Protective Conditioner.

Pro Tip: This shampoo creates the perfect, ultra-clean canvas for biotechnology treatments. If it is a "treatment day" where you plan to use the K18 Leave-In Molecular Repair Hair Mask, wash with this shampoo, skip the conditioner entirely, towel-dry thoroughly, and apply the mask directly to your damp strands for maximum absorption.
