THE PERFECT SHAMPOO FOR ALL HAIR TYPES - NYK1 Salt & Sulphate Free Shampoo has a gentle cleansing formula designed to protect and nourish your hair. This sulphate free shampoo helps extend the life of hair treatments, including keratin, colour, and smoothing treatments. Enriched with coconut oil to lock in moisture and deliver lasting hydration, it leaves your hair super soft, shiny, and manageable. Ideal for dry, damaged, or chemically treated hair, this non-stripping, salon-quality shampoo keeps your hair healthy, smooth, and frizz-free.
SAFE FOR HAIR EXTENSIONS - Hair extensions are specially treated and require gentle care, but regular shampoos and conditioners can be too harsh and may cause damage. This can leave extensions dry, dull, tangled, and faded, and make curls drop faster. Our gentle sulphate and salt free shampoo is specially formulated to protect adhesive bonds, maintain softness and shine, and help your extensions stay beautiful, tangle-free, and long-lasting.
PROTECTS AND MAINTAINS VIBRANT COLOUR - Regular shampoos and conditioners can fade your colour in just a few washes, leaving your hair dull and less vibrant. Protect your investment and prolong your vibrant shade with this Salt & Sulphate Free shampoo, specially formulated to gently cleanse and nourish coloured hair without stripping your colour.
IDEAL FOR KERATIN & BRAZILIAN TREATMENTS - A must have salt & sulphate free shampoo specially formulated to protect and extend the life of your Keratin or Brazilian Treatment. Regular shampoos with salts can strip your treatment within just a few washes. To further maintain smooth, frizz-free results for up to 3-4 months, use with NYK1 Salt & Sulphate Free conditioner.
GENTLE SULPHATE & PARABEN-FREE FORMULA - Formulated to cleanse without stripping moisture or natural oils, helping maintain a healthy scalp and hair. Protects your keratin treatments, hair bonds, permanent waves, and colour treated hair for longer-lasting results. The gentle formula helps reduce exposure to harsh ingredients, supporting a healthier scalp and hair.
