NYK1 SALT Sulfate-Free Shampoo & Conditioner Set for Color-Treated Hair — 2 x 16.9 fl oz, Keratin-Safe, Paraben-Free

NYK1 SALT sulfate-free shampoo and conditioner set is a gentle two-step system designed to cleanse and condition color-treated, keratin-treated, and extension-enhanced hair without stripping bonds, coatings, or pigments.

This daily duo pairs a non-sulfate shampoo with a lightweight yet nourishing conditioner to extend the life of professional services like Brazilian keratin and color treatments, while keeping extensions smooth and manageable. Free from sodium chloride, sulfates, and parabens, the formulas focus on gentle cleansing and moisture balance so processed hair looks healthier, shinier, and lasts longer between salon visits.

How does this set protect keratin and smoothing treatments?

The formula avoids salt and harsh sulfates that can weaken protein-bonded coatings and speed up treatment breakdown. It provides a low-foaming, non-stripping cleanse that helps maintain the integrity of keratin and smoothing services while preserving slip and softness.

• Zero sodium chloride and sulfate surfactants reduce bond disruption.
• Conditioner restores moisture without weighing treated hair down.
• pH-balanced approach helps preserve professional coatings and shine.

Will this set keep my color from fading too quickly?

Yes — by avoiding aggressive detergents, the shampoo minimizes color leaching and the conditioner seals cuticle layers to lock in pigments longer. Regular use helps maintain vibrancy between color appointments while reducing dullness caused by harsh cleansing agents.

• Sulfate-free cleansing to protect dye molecules from rapid loss.
• Moisture-balancing conditioner that smooths cuticles for improved color reflection.
• Formulated to be safe for repeated use on color-treated hair.

Is this suitable for hair extensions and fine hair?

The set is formulated to be gentle on delicate hair types and extensions: the shampoo cleans without heavy residue, and the conditioner nourishes without excessive weight. For extension wearers or those with finer strands, applying conditioner away from the roots keeps volume intact while conditioning lengths and ends.

• Lightweight conditioning avoids matting or slip buildup at the bond area.
• Shampoo removes oils and product without stripping adhesive points.
• Recommended conditioner application: start an inch from the scalp for fine or extension hair.

How does this routine differ from everyday drugstore products?

Many mainstream shampoos use sodium chloride and strong sulfates that create aggressive lather but can accelerate loss of treatments and color. NYK1 SALT prioritizes milder surfactants and clean ingredients so performance focuses on long-term preservation rather than immediate foaminess.

• No salt, no sulfates, no parabens — reduced irritants for sensitive scalps.
• Balanced formulas that cleanse effectively without de-bonding coatings or color.
• Two 16.9 fl oz bottles deliver salon-oriented aftercare at home.

Who is this for? This shampoo and conditioner pair is ideal for anyone with chemically processed hair — from clients fresh out of the salon after keratin or Brazilian blowout treatments to people with color-treated tresses or bonded extensions. It also suits those with fine or sensitive hair seeking a gentler daily cleanse that preserves professional treatments and enhances shine without heavy buildup.
