We put 23 shampoos for coloured hair to the test. Which give a longer lasting colour?

Supermarket shelves are full of shampoos for coloured hair making claims such as “helps fight fade out”, “keeps colour looking vibrant”, or “helps prolong colour”. Your hairdresser has probably recommended using an expensive colour-safe shampoo to prevent your colour fading. But do colour-care shampoos make a difference? You might be surprised at our results.

If you spend money on hiding those annoying grey hairs or want to liven up your do with a new hue, you want the colour to last as long as possible. So it makes sense to buy a shampoo specifically for coloured hair … and many of us do. According to figures from the Cosmetic Toiletry and Fragrance Association, Kiwis spend at least $3.1 million a year buying shampoo for coloured hair.

To find which shampoo gives a longer lasting colour, we put 23 shampoos for coloured hair to the test. We also included TRESemme Deep Cleansing Shampoo (a shampoo for all hair types), Johnson’s Baby Shampoo and water.
