NYK1 Salt & Sulfate-Free Shampoo for Color & Keratin-Treated Hair, 17 fl oz — Hydrating, Extension-Safe Formula

NYK1 Salt & Sulfate Free Shampoo is a gentle, 500ml cleansing shampoo formulated to protect and extend the life of keratin treatments, color, and hair extensions while delivering moisture and shine.

Everyday shampoos that contain salts or sulfates can prematurely fade color, weaken keratin bonds, and dry out extensions. This NYK1 formula cleanses without stripping, using coconut-derived hydration to keep hair soft, manageable, and less frizzy. It’s designed for unisex use and works across hair types, especially on chemically treated, dry, or damaged hair that needs extra protection after salon services.

How does this shampoo help preserve keratin and Brazilian treatments?

The sulfate- and salt-free composition prevents aggressive stripping of smoothing treatments, so keratin and Brazilian straightening last longer between salon visits. Regular use maintains the treatment’s smoothing effect by keeping proteins intact and minimizing frizz.

• Formulated without sulfates or salts to avoid breaking keratin bonds
• Gentle cleansing keeps smoothing treatments effective for months
• Maintains softness and reduces the need for frequent touch-ups

Will it protect color-treated hair and prevent fading?

Yes — the shampoo removes dirt and buildup while being mild enough to avoid stripping color molecules. It helps preserve vibrancy and shine so dyed hair looks fresher after more washes compared with standard detergents.

• Non-stripping surfactants protect color pigments
• Coconut-derived moisture reduces dullness and enhances gloss
• Use with NYK1 sulfate-free conditioner for best color retention

Is this safe for hair extensions and bonded systems?

The gentle formula is designed to protect adhesive bonds and delicate extension hair, preventing dryness, tangling, and premature curl drop. It cleans without roughing cuticles, helping extensions remain soft and manageable longer.

• Free from salts and sulfates that can weaken extension bonds
• Hydrating ingredients maintain softness and reduce tangles
• Helps preserve extension color and texture between appointments

What kind of hair will benefit most from NYK1 Salt & Sulfate Free Shampoo?

This shampoo suits dry, chemically treated, or fragile hair that needs gentle care: keratin and Brazilian-treated hair, color-treated strands, extensions, and hair recovering from damage. It’s also a good everyday option for anyone seeking milder cleansing without harsh ingredients.

• Recommended for keratin, color, and smoothing treated hair
• Works well on dry, brittle, or heat-stressed hair
• Unisex formula suitable for salon and at-home maintenance
