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

NYK1 SALT sulfate-free shampoo and conditioner set is a gentle, no-sulfate, no-salt duo formulated to preserve color, keratin treatments and hair extensions while cleansing and conditioning without stripping.

This two-bottle value pack (2 x 16.9 fl oz / 500 ml each) pairs a mild, non-stripping shampoo with a balancing conditioner designed for processed and treated hair. The formulas avoid sulfates, sodium chloride (salt) and parabens, so they help maintain professional treatments such as Brazilian keratin straightening, color services and attachment systems. Use the set as your regular aftercare to keep bonds, coatings and dye vibrancy intact while still removing oils and build-up.

How does this set protect keratin and smoothing treatments?

Because the shampoo and conditioner are free from sulfates and salt, they do not aggressively strip the keratin coatings or weaken treatment bonds. The gentle surfactants cleanse without opening or breaking the treatment layer, helping the smoothing effect last longer between salon visits.

• Sulfate- and salt-free formulas that minimize bond disruption
• Gentle cleansing preserves keratin coatings
• Conditioner smooths and detangles without heavy buildup
• Recommended for post-treatment aftercare and maintenance

Will this set keep hair color from fading faster?

Yes — the NYK1 color-protecting shampoo and conditioner are formulated to be non-stripping, reducing pigment loss compared with harsh, sulfate-rich products. They gently remove surface residues while helping maintain color saturation and shine.

• No sulfates or salts that accelerate color washout
• Balanced conditioning keeps hair smooth and reflective
• Suitable for both permanent and semi-permanent dyes
• Regular use helps color look vibrant longer

Can I use these on hair extensions and fine hair safely?

The set is suitable for all hair types, including fine hair, oily scalps and extensions. The shampoo cleans effectively without heavy surfactants, and the conditioner delivers moisture without weighing fine strands down when applied correctly.

• Conditioner advice: apply an inch from the roots for extensions or fine hair
• Non-stripping shampoo reduces slipping or loosening of bonded extensions
• Lightweight conditioning maintains movement and shine
• Safe for repeated use as part of extension aftercare routines

What ingredients are avoided and why does that matter?

The formulas deliberately exclude sulfates (SLS/SLES), sodium chloride (salt) and parabens. Those omissions reduce the risk of drying, color fading and treatment de-bonding, while still providing effective cleansing and conditioning for processed hair.

• No sulfates — gentler lather, less pigment stripping
• No salt — helps preserve keratin and extension bonds
• Paraben-free — avoids certain preservatives some users prefer to skip
• Formulated for compatibility with salon treatments and daily care

Who this is for: This NYK1 SALT shampoo and conditioner duo is aimed at anyone who wants to protect professional hair work — people with keratin or Brazilian blowout treatments, freshly colored hair, or attached hair extensions — plus those with fine or chemically processed hair who need a gentle, maintenance-focused wash-and-condition routine. Keep using both products together for best results: the shampoo cleans without stripping, and the conditioner restores smoothness and manageability without heaviness.
