Blondes everywhere know that Violet and Blue shampoos can help maintain salon blonde hair for longer, keeping the tone fresh and vibrant and eliminating the chance of yellow or orange tones appearing.

But how do they work? Let’s go back to school and art lessons where we learnt about colours and how the interact with each other by enhancing or neutralising.

All colours have the capability of neutralising their opposites. If, for example you have green hair and wanted to neutralise it, the opposite of green is red. If you apply a red colour over green hair, you don’t get red hair, you get something neutral, depending on how light or dark the colours used are it will create a muted brown.

When it comes to blondes, the lighter the salon colour, the paler the violet needs to be to help maintain a clean blonde, likewise, the darker the blonde is the more deeper the violet ior blue needs to be to help neutralise the unwanted tones.

Naturally it isn’t as simple as the colour wheel above suggests, but the one below gives a clearer idea of how complex and precise anti yellow shampoo needs to be to be able to work on different levels and tones of blonde. And whilst this image relates to colour in a broader spectrum, the principles are the same for everything.
