Shampoo for coloured hair

You’re rocking your new hair colour, and you really don’t want it to go down the drain in your first few washes. But hair care products can quickly strip hair dye; even spending time outdoors can fade your vibrant new shade.

• Down the drain
• ÌÇÐÄVlog verdict

Salon and supermarket shelves are stocked with ‘colour care’ products that make claims like “keeps colour looking vibrant”, “10 weeks’ colour protection” and “helps prevent colour fade” – but does using a colour care shampoo actually make any difference?

The test

We tested 28 colour care shampoos (listed in the table below) alongside Tresemmé Deep Cleansing Shampoo  (a popular general shampoo for all hair types), Johnson’s Baby Shampoo, and washing just with water. Samples of blonde human hair were dyed using three red hair dyes – Schwarzkopf Brilliance 43 Red Passion and L’Oréal Preference P67 Scarlet Intense Red, available from supermarkets, and Cosmo Service Personal Colour Intense Red Light Blonde, purchased from a salon warehouse.

The laboratory assessed:

• Effect of washing by subjecting each sample of hair to 12 washes with each shampoo. The colour intensity was measured using a spectrophotometer before and after washing.
• Effect of UV exposure by exposing a portion of each hair sample (after being washed 12 times) to the equivalent of six weeks’ exposure to summer daylight. The colour change of the exposed and unexposed sections was then compared.  

Down the drain

In our test, washing hair with water caused the least colour change after 12 washes. 

When comparing shampoos, there’s no clear winner. Although we didn’t test these shampoos with their respective conditioners, the Nourish Coloured Hair Shampoo technically caused the least amount of colour change, while the Pantene Pro-V Colour Therapy was considered to have caused the most change. But can you pick it from the image?

Hair sample 1 is dyed with L’Oréal Preference, pictured before any washing. The other samples show the colour change after 12 washes in the specified shampoo (or water).

1. Control – L’Oréal Preference
2. Water
3. Nourish Naturals Coloured Hair Shampoo
4. Schwarzkopf Extra Care Hair Repair With Liquid Keratin Ultimate Colour Shampoo
5. Tresemme Deep Cleansing Shampoo (popular general shampoo for all hair types)
6. Ecostore Dry, Damaged, Coloured Shampoo
7. Pantene Pro-V Colour Therapy

Even when it comes to UV protection, none of the shampoos appear to offer any specific benefits. However, we did find that of the three hair dyes chosen, the Schwarzkopf Brilliance dye held the colour better than the L’Oréal Preference, which had the most colour change. Statistically, the Cosmo salon dye wasn’t better or worse than the other two.

ÌÇÐÄVlog verdict

These colour care shampoos can be pricier than standard formulations (the regular Tresemme and the baby shampoo both cost under $2 per 100mL), but spending more doesn’t mean you’ll get better results. You can pay anywhere from $0.88 to $13.60 per 100mL for the shampoos we tested. Whether stated or not, these products want us to believe that you can have the ‘just dyed’ look for longer, but this isn’t the case. 

Based on our results, investing in these types of shampoos won’t guarantee you the results you’re looking for. So if you really want a ‘colour care’ shampoo, you might as well just buy a cheap one. Alternatively, why not buy a good general shampoo the whole household can use?
