Keratin Complex Keratin Care Smoothing Shampoo 33.8 fl oz — sulfate- and sodium-chloride–free, frizz control & shine

Keratin Complex Keratin Care Smoothing Shampoo is a sulfate- and sodium-chloride–safe cleansing formula that reduces frizz, restores tensile strength, and boosts shine for all hair types.

This salon-grade shampoo from Keratin Complex blends keratin with soy and wheat proteins to gently remove buildup while supporting smoother, more manageable hair. Sized at 33.8 fl oz, the pump-ready bottle is designed for regular use on natural, color-treated, or keratin-treated hair. The formula avoids sodium chloride to help preserve professional smoothing treatments and deliver lasting softness without stripping vital moisture.

How does this shampoo control frizz while still cleansing?

The product uses a keratin-enriched surfactant system that lifts oil and dirt without roughing up the hair cuticle. Protein ingredients then sit on the fiber to fill gaps in damaged areas, leading to a sleeker surface and reduced flyaways. It balances effective cleansing with conditioning agents to prevent dryness.

• Keratin, soy, and wheat proteins smooth the hair shaft.
• Sulfate-compatible cleansing agents that avoid harsh stripping.
• Formulated without sodium chloride to protect smoothing treatments.

Will this damage keratin or smoothing treatments?

No — the formula is engineered to be compatible with keratin and other professional smoothing services. By excluding sodium chloride, it minimizes the risk of prematurely degrading treatment results, helping maintain the treated hair’s smoothness and longevity when used as directed.

• Sodium-chloride–free to reduce treatment wear-off.
• Gentle cleansing preserves treatment integrity.
• Regular use supports longer-lasting smoothness.

Is this suitable for dry, damaged, or color-treated hair?

Yes — the blend of proteins and moisturizing components is chosen to both cleanse and replenish hair that needs more strength and shine. It helps reduce roughness and improves manageability without compromising color or texture when paired with a compatible conditioner.

• Restores moisture and reduces brittleness.
• Adds body while keeping hair soft to the touch.
• Safe for color-treated hair when used with color-friendly conditioners.

How should I use the 33.8 fl oz bottle for best results?

Wet hair thoroughly, apply a small amount, and lather from roots to ends; rinse and repeat if hair is heavily soiled. For optimal smoothing and hydration, follow with a Keratin Complex conditioner or treatment and style as usual. The larger size is ideal for multiple months of regular use at home or in a salon setting.

• Use 2–3 pumps for medium-length hair; adjust for thickness.
• Pair with a Keratin Complex conditioner for best smoothness.
• Store upright; keep cap closed to protect formula longevity.

Who is this for: Professional stylists and at-home users seeking a reliable, treatment-friendly shampoo that tackles frizz and supports hair resilience. It suits anyone with dry, weakened, color-treated, or keratin-treated hair who wants a gentle-cleansing, protein-rich formula in a generously sized bottle.
