If you’ve got dyed hair then preserving your colour at home has never been easier — especially for bottle blondes.

This is where you need some purple shampoo in your life. Delicate, clean blonde hair colour in particular can tend to fade faster, lose shine, and can look brassy or yellow very fast.

So what is a purple shampoo?

It contains purple pigment to neutralise brassy and yellow tones on lighter hair. It’s purple because on the colour wheel it’s the direct opposite colour of yellow, so essentially they cancel each other out. So purple shampoo on dyed hair with yellow tones can “colour correct” your hair’s hue, restoring it to a more natural tone.

Are purple shampoos just for blondes?

No - they can also be used to boost grey or brunette hair with golden highlights.

How and when should you use purple shampoo?

To use a purple shampoo, wet the hair and lather on the formula. Once applied evenly, leave it on for two to four minutes depending on the amount of brassiness or yellow in the hair. When rinsing the shampoo out of your hair, use cool water, which will help close the cuticle and seal the colour.

Start by using purple shampoo once a week and build up if needed. Purple shampoo helps keep colour fresh, but it’s important not to over-use it. If you start to notice too much purple tone in your hair, it’s time for a break!
