Salts and Sulphates are Abrasive and can alter the Colour and Strip the Treatment


This product does not contain Sodium Lauryl Sulfate, but instead it contains SLSA. It is a common misconception that these ingredients are the same thing when in fact they are entirely different. SLS is a harsh stripping, cheaper alternative to the more natural SLSA which is much more mild as a natural hydrophilic cleanser. Importantly our product is also free of Sodium Chloride and all other salts that may damage your hair and shorten the life of your hair treatment.


"I designed my no nonsense shampoo this way because I personally have all 4 hair treatments, colour, bleach, keratin and extensions.

After trying many well known competitor products I was so fed up with Salt & Sulphate Free Shampoos that just cleanse efficiently, but left the hair dull and lifeless. I found that they sneakily include the things that actually stripped hair and damaged the treatment, using synthetic silicones to attach to your hair so that you temporarily feel detangled and conditioned, but in fact there is no conditioning element at all.

My Shampoo cleanses well without stripping. It's then important to use NYK1 Conditioner. It's a rich consistency and conditions very well and will detangle your hair perfectly; protecting against blow drying, styling, straighteners and the elements. Avoid roots if you have fine or limp hair.

I'm confident that this is the best out there right now. My Shampoo & Conditioner are recommended by hair salons worldwide xxx"

How long does a bottle of NYK1 Salt & Sulphate Free Shampoo or Conditioner last?

NYK1 Salt & Sulphate Free Shampoo and Conditioner typically last between two and four months depending on frequency of use.

Isn't the ingredient "Sodium Lauryl Sulfoacetate" bad for your hair??

Sodium Lauryl Sulfoacetate (SLSA) has a completely different profile in terms of performance and mildness compared to Sodium Lauryl Sulfate (SLS).
