K18 Damage Shield Color-Safe Shampoo, 8.5 fl oz — pH-Balanced, Color Protection & Frizz Reduction

K18 Damage Shield Color Safe Shampoo is a pH-optimized, color-safe cleanser that removes dirt and oil while protecting color, reducing frizz, and preserving hair health.

This shampoo is formulated for colored and damaged hair that needs a thorough but gentle wash. Using plant-derived surfactants and a pH balanced base, it cleans without over-swelling the hair cuticle, helping to keep color vibrant, reduce tangling, and enhance shine. The formula includes the brand’s signature K18PEPTIDE to help lower protein loss and a certified microbiome-friendly profile to protect the scalp barrier.

How does this shampoo protect hair color during washing?

The shampoo’s pH-optimized formula limits excessive cuticle opening, which reduces the amount of color stripped during cleansing. Mild, plant-based surfactants remove oils and residues without aggressively extracting dye molecules, so color lasts longer between salon visits.

• pH-balanced to minimize cuticle swelling
• Plant-derived surfactants that cleanse without harsh stripping
• Formulation aimed at preserving dye adherence and vibrancy

Will this shampoo help reduce frizz and tangles?

Yes—by cleaning without over-drying and by maintaining cuticle integrity, the shampoo helps hair lie smoother and detangle more easily. Reduced cuticle disruption leads to less friction between strands, which lowers frizz and shortens styling time.

• Mild cleansing to avoid excessive drying
• Cuticle-friendly pH to maintain smooth strand surfaces
• Improved slip for easier combing and less breakage

Is this gentle enough for everyday use and sensitive scalps?

The formula is designed to be gentle for regular use: it mimics hair’s natural pH and avoids harsh surfactants that disrupt the scalp’s protective microbiome. That means you can cleanse frequently without stripping essential oils or upsetting scalp balance.

• Microbiome-friendly certification to protect scalp health
• Gentle plant-derived cleansers safe for frequent washing
• Designed to support both hair and scalp comfort

What role does the K18PEPTIDE play in the shampoo?

The included K18PEPTIDE helps reduce protein loss during cleansing, supporting the hair’s structural integrity. While the shampoo is primarily a cleanser, the peptide contribution helps hair feel stronger and less prone to damage from everyday washing and styling.

• Helps lower protein loss during washing
• Supports hair strength and resilience
• Complements other K18 treatments in a haircare routine

Who is this for: This shampoo is a match for people with color-treated, chemically processed, or mechanically damaged hair who want a reliable daily or regular cleanser that preserves color and supports hair health. It’s suitable for anyone seeking a gentler, scalp-friendly alternative to harsh clarifying shampoos, including those who use frequent styling tools or chemical services.
