K18 Damage Shield Protective Shampoo 16 fl oz — Gentle, Frizz-Reducing Daily Cleanser for Color-Treated Hair

K18 Damage Shield Protective Shampoo is a daily-use cleansing formula that reduces frizz and tangles while helping maintain the appearance of healthy, resilient hair.

This lightweight, 16 fl oz bottle from K18 combines gentle surfactants with smoothing and conditioning ingredients to cleanse without stripping. It’s designed for hair that needs improved manageability and protection from dryness and static, making styling easier and helping preserve salon treatments. The formula focuses on detangling, reducing frizz, and supporting an overall smoother finish after washing.

How does K18 Damage Shield help reduce frizziness?

The shampoo's mild cleansing agents remove buildup that contributes to flyaways while moisturizing components smooth the hair surface. This reduces static and the visual signs of frizz so hair lays flatter and feels softer.

• Gentle surfactants cleanse without over-drying
• Conditioning agents smooth cuticle scale
• Lightweight formula avoids weighing hair down
• Helps maintain humidity resistance for a neater finish

Will it make detangling easier after washing?

Yes — the formula is designed to improve slip during rinsing and conditioning, so combs and hands move through hair with less resistance. That reduces breakage from tugging and leaves hair easier to style.

• Improved slip cuts down on brushing stress
• Works well with leave-in conditioners and serums
• Suitable for wet detangling for all hair types

Is this shampoo safe for color- and chemically-treated hair?

K18 Damage Shield is formulated to be gentle enough for color-treated and chemically processed hair, helping preserve treated hair’s appearance by avoiding harsh stripping. It supports manageability so styles last longer between salon visits.

• Non-stripping cleansing helps protect color vibrancy
• Gentle on chemically-treated textures and finishes
• Works as part of a maintenance routine for treated hair

How should I use this 16 fl oz bottle for best results?

Apply a small amount to wet hair, lather focusing on the scalp, then rinse thoroughly before following with conditioner or a treatment. For thicker or dirtier hair, a second lather can be used; finish with a detangling conditioner if desired.

• Work into wet hair and scalp, then rinse well
• Repeat if hair is very oily or product-laden
• Pair with a K18 conditioner or treatment for optimal results
