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

NYK1 SALT Sulfate-Free Shampoo and Conditioner is a gentle two-step system that cleanses and conditions color-treated, keratin-treated hair and extensions without sulfates, salt or parabens.

This duo (two 16.9 fl oz / 500 ml bottles) is formulated to protect processed hair by avoiding harsh detergents and sodium salts that can strip color, weaken bonds from keratin treatments, or reduce the lifespan of hair extensions. Lightweight yet nourishing, the pair aims to maintain shine and manageability while minimizing fading and de-bonding after professional treatments.

How does this set protect color and extend vibrancy?

The sulfate- and salt-free cleansing base avoids aggressive surfactants that accelerate dye wash-out, helping pigments stay vibrant between salon visits. The conditioner deposits moisture and smoothing agents that lock in shine and reduce surface roughness where color fades fastest.

• Gentle surfactants cleanse without stripping pigment
• Conditioner smooths the hair cuticle to retain color
• Paraben-free formulation reduces exposure to harsh preservatives
• Large 500 ml bottles provide longer between-purchase use for treated hair

Will this work with keratin treatments or Brazilian blowouts?

Yes — the formula omits salt and sulfates that can prematurely break down the keratin coating applied during straightening treatments. Regular use helps preserve the smoothing effect and reduces the need for frequent touch-ups.

• No sodium/salt to avoid de-bonding of keratin coatings
• Hydrating conditioner supports the treatment’s smooth finish
• Balanced cleansing protects treatment longevity without residue

Is this suitable for hair extensions and fine hair?

The set is crafted for gentle performance: the shampoo thoroughly cleanses while minimizing tangles, and the conditioner nourishes without weighing hair down when applied away from the roots. For extensions and fine hair, applying conditioner from mid-length to ends prevents slippage and buildup near attachment points.

• Shampoo cleans without heavy buildup that stresses bonds
• Conditioner is rich but lightweight to avoid flattening fine hair
• Recommended: apply conditioner an inch from roots for extensions

How does it behave on oily scalps or textured hair?

The sulfate-free cleansing system removes excess oils effectively while preserving natural moisture balance, making it suitable for oily roots paired with drier ends. Textured and chemically treated hair benefit from the smoothing conditioning ingredients without exposure to harsh salts that can create frizz and breakage.

• Thorough but gentle cleansing for oily scalps
• Conditioner manages frizz and improves detangling on textured hair
• Formulated to avoid irritation and preserve hair structure

Who is this for? NYK1 SALT Sulfate-Free Shampoo and Conditioner is intended for anyone with color-treated, keratin-treated or extended hair who wants a mild, preservative-conscious aftercare routine. It also suits people with fine, oily, or textured hair looking to protect salon treatments and maintain smoother, longer-lasting results from home care.
