K18 Damage Shield Protective Shampoo — 8.5 oz Color-Safe, pH-Balanced Frizz Control & Detangling

K18 Damage Shield Protective Shampoo is a color-safe, pH-optimized cleansing formula that reduces frizz and tangles while helping maintain hair health and shine.

This lightweight shampoo is formulated to provide a deep, efficient clean without stripping color or upsetting the scalp microbiome. Designed for damaged, chemically treated, or frequently styled hair, the formula uses plant-derived surfactants and K18PEPTIDE to minimize protein loss and control cuticle swelling during washing. The result is smoother, more manageable hair with preserved color brightness and a healthier-feeling scalp.

How does this shampoo protect color and manage frizz?

K18 Damage Shield uses a pH-optimized system that limits excessive cuticle swelling while washing, which helps lock in color and reduce surface roughness that causes frizz. Gentle surfactants remove oil and buildup without harsh stripping, preserving shine and manageability.

• pH balanced to mimic hair’s natural acidity and reduce cuticle lift
• Color-safe cleansing agents to prevent premature fading
• Frizz control by minimizing cuticle disruption during shampooing

Will it work on chemically treated or damaged hair?

Yes — the formula was designed specifically for damaged and chemically processed hair. It cleans effectively while supporting hair structure through peptide support, leaving strands easier to detangle and style after rinsing.

• K18PEPTIDE helps reduce surface protein loss from color and chemical processes
• Gentle enough for daily or regular use without over-drying
• Helps improve wet detangling to reduce breakage during conditioning

How gentle is the shampoo on scalp and hair daily?

The shampoo’s microbiome-friendly formulation removes dirt and oil without disrupting the scalp’s natural protective barrier, so it’s safe for frequent use. Its plant-derived surfactants and pH tuning aim to maintain scalp balance while keeping hair soft and resilient.

• Certified microbiome-friendly to support scalp health
• Plant-derived surfactants for effective yet gentle cleansing
• Formulated to mimic hair’s natural pH for daily compatibility

What results can I expect after using K18 Damage Shield?

Expect cleaner, more manageable hair with less frizz and fewer tangles, plus improved surface shine and preserved color tone. Over repeated washes, hair feels healthier thanks to reduced protein loss and minimized cuticle damage during cleansing.

• Noticeable reduction in tangles and surface roughness after rinsing
• Shinier, more vibrant color retention with regular use
• Smoother styling and fewer breakage points when detangling

Who is this for: K18 Damage Shield Protective Shampoo is intended for people with color-treated, chemically processed, heat-styled, or otherwise damaged hair who want an effective cleanse without sacrificing color, scalp balance, or hair strength.
