What is a purple shampoo?

Purple shampoo, also commonly known as silver shampoo, is a colour theory at its simplest: The temporary hue makes all types of light and blonde hair look fresh-from-the-salon radiant.

Every purple-coloured shampoo formula contains purple pigment to neutralise brassy and yellow tones on lighter hair. That’s because purple is the direct opposite colour of yellow on the colour wheel, which means purple and yellow will cancel one another out.

So, when using purple pigment on colour-treated brassy or yellow tones, it colour-corrects your hair’s hue, restoring it to its former natural or neutral brightness with cooler tones.

While purple shampoos are particularly popular among blondes, they can also be used to boost grey or brunette hair with golden highlights.

A word of caution, though: If your hair starts to take on a lavender (or blue) tint, cut back to one or two washes per week, and supplement with your regular shampoo.

Contrary to popular belief, purple shampoo isn’t just for blondes. As the fundamental purpose of a silver shampoo is to eliminate unwanted brassiness, it’s also useful to anyone who wants to get rid of rusty-looking hair too.

Asian hair, for example, ranges from dark brown to brown and naturally has these brassy tones, so a purple shampoo can be used on ash, brown, or highlighted hair to help tone hair strands and get a brown hue that looks healthier and brighter.

In terms of hair colour, South Asian hair has the highest levels of red pigments and melanin as compared to North Asians and Caucasians.

As a result, we experience a lot of deceptive colour payoff where the final hair colour after dyeing does not match the hair colour selected.

Another problem? We also tend to get unwanted brassiness that appears ‘rusty’, or dull and unhealthy hair, that starts to show when the colour begins to fade off.

The workaround to this issue? A purple shampoo, of course.

How do you choose the right purple shampoo formula for your hair?

The most important thing to do is to look for a shampoo with purple pigments. A good purple shampoo should come with concentrated purple pigments and the texture and consistency of the product should be opaque, not translucent to ensure there are enough colour pigments in each wash to neutralise the brassiness in your hair.

Apart from the number of purple pigments present to neutralise brassiness, it is also crucial that the formula doesn’t contain harsh salts and surfactants (think sulphates such as SLS and SLES) that can strip the hair from moisture and colour, resulting in premature colour fading.

This applies to all dyed and coloured hair such as brown, ash, bleached, highlighted, and blonde. If you have black hair, you can skip the purple shampoo.

The frequency and duration of using purple shampoo will affect the level of toning, so do allow some time for the formula to work its magic as neutralisation generally gets better with regular usage.

We have two tips that can help:

  • Use the purple shampoo on semi-wet (instead of dripping wet) hair and gently squeeze dry the hair with the hands or a towel before applying the purple shampoo. This ensures that the purple pigments are not diluted by the water and helps with its penetration into the hair cuticle.
  • Leave the purple shampoo on for longer (up to 10 minutes). The longer you leave the product in the hair before rinsing, the more the purple pigments can penetrate into the hair to neutralise the yellow and orange tones, resulting in longer-lasting effects.
