Keratin Complex Keratin Care Smoothing Shampoo 33.8 fl oz — sulfate-free, frizz-reducing daily formula

Keratin Complex Keratin Care Smoothing Shampoo is a sulfate-free, sodium-chloride–free cleansing formula that reduces frizz, restores moisture, and reinforces hair strength for all hair types.

Designed for daily use on dry, damaged, color- or keratin-treated hair, this professional-grade shampoo combines keratin with soy and wheat proteins to gently cleanse while improving manageability and shine. The 33.8 fl oz size is ideal for salon use or at-home routines where consistent smoothing and protection of keratin treatments are priorities.

How does this shampoo reduce frizz without stripping hair?

The formula avoids harsh salts and sulfates that can remove natural oils and degrade smoothing treatments. Instead, it uses protein-enriched ingredients that help seal the hair surface, improving slip and reducing static. Regular use keeps strands smoother and easier to detangle.

• Free of sodium chloride to protect keratin treatments
• Protein blend of keratin, soy, and wheat to reinforce the cuticle
• Gentle surfactants that cleanse without over-drying
• Improves comb-through and reduces breakage during styling

Will this work on color-treated, chemically processed, or naturally curly hair?

Yes—the gentle cleansing base and strengthening proteins make it suitable across textures and treatments. For color-treated or chemically processed hair, the mild formula helps maintain vibrancy and prevents accelerated fading. Curly hair benefits from enhanced moisture and reduced frizz without weighing curls down when used correctly.

• Safe for keratin-treated and color-treated hair
• Supports moisture balance for dry or porous hair
• Compatible with curly and wavy textures for definition
• Helps reduce tangles common after chemical services

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

Apply a small amount to wet hair, emulsify into a lather focusing on the scalp, then rinse thoroughly. For thicker or longer hair, repeat if needed and follow with Keratin Complex conditioner or mask to lock in smoothing benefits. Use consistently to maintain the protective effect on keratin treatments.

• Use a coin-size amount for short hair; more for longer hair
• Lather at the scalp to remove oils and buildup
• Rinse fully and follow with matching conditioner
• Ideal for daily or regular salon use due to large size

What tangible hair improvements can I expect and when?

You can expect softer, shinier hair and fewer flyaways after the first few washes as surface smoothing takes effect. Strengthening proteins help reduce breakage over weeks of regular use, while protection from sodium chloride helps extend the life of keratin treatments. Results vary by hair condition and styling routine.

• Immediate improvement in manageability and shine
• Noticeable frizz reduction within a few washes
• Gradual strengthening and less breakage with continued use
• Better maintenance of professional smoothing treatments

Who is this for? Keratin Complex Keratin Care Smoothing Shampoo in the 33.8 fl oz size is aimed at stylists, frequent users, and anyone with dry, damaged, chemically treated, or frizz-prone hair who wants a salon-quality shampoo that cleanses gently while supporting smoother, stronger strands. Choose this bottle if you need a larger supply for consistent at-home care or salon use and prefer a formula that complements keratin services.
