Meet the purple wonder product that can banish brassy tones and save blonde hair

Purple shampoo is every colourist’s saviour product. If a client with lightened hair is using one (the right way), they’re one step ahead with their hair colour aftercare #goldstar.

Yes, the colour’s ridiculously pretty but don’t underestimate the power of purple shampoo when it comes to keeping your hair colour tones under control. Whether it’s blonde hair or grey hair, purple shampoo can rescue the tones in lightened hair - with pretty instant results.

Time to wise up on the power of purple shampoos. Your colourist will thank you for it.


So what exactly is purple shampoo and why do you need it? Lightened hair (especially blonde hair) needs extra aftercare to keep the colour salon-fresh and banish unwanted warm tones.

Put simply, the purple pigments in purple shampoo counteracts the unwanted yellow in cool blonde tones. So, if you can’t seem to keep your hair at just the right blonde or grey tone, purple shampoo could be the answer for keeping those brassy tones at bay. It’s the aftercare hack that can make a big difference to lightened hair if you start using purple shampoo in your regime just once a week.

Put purple shampoo on your radar if you have light coloured hair - it can be salon achieved or natural. Think blonde, platinum, silver, grey, white, or cool pastel tones. Because purple shampoo is made especially for light hair, it won’t make a difference to brunette colour unless you have blonde highlights to maintain.

Purple shampoo doesn’t have to feel harsh on your hair to work its colour corrective magic. For a natural, paraben-free formula, step forward Biolage’s new ColorLast Purple Shampoo (aka your blonde BFF for counteracting unwanted yellow tones with its hard-working purple pigments).

More than a purple shampoo, its nourishing, vegan-friendly formula contains fig and orchid extracts to help cool-toned blonde or grey hair feel two and a half times softer, with three times less breakage. It’s the ultimate aftercare for maintaining your hair colour until your next salon visit.

So what’s the difference between the ColorLast Shampoo and ColorLast Purple Shampoo? While the ColorLast Shampoo protects and maintains your lightened hair, the ColorLast Purple Shampoo specifically contains purple pigments to neutralise any unwanted warm or yellow tones.


A common misconception with newbie purple shampoo users is that you use it instead of your regular shampoo. We get it, it’s amazing, but start off by using purple shampoo once or twice a week max – you can always build up the usage if you need to.

Alternate your hero purple shampoo, like Biolage ColorLast Purple Shampoo, with your regular colour care shampoos, like Biolage ColorLast Shampoo or Biolage R.A.W. Color Care Shampoo for Color Treated Hair - both gently cleanse but keep your hair colour vibrant. You can also mix your purple and regular colour care shampoo together for less violet deposit in your hair.

If you start to notice a purple or violet tone in your hair once it’s dry, put the purple shampoo down and take a breather. Using a clarifying shampoo will remove any hints of purple residue.


Want to know how to use purple shampoo at home? Read on for our pro purple shampoo how-to. If you’re not sure on the optimum frequency for using purple shampoo on your hair colour and type, ask your colourist for their advice.

1: Keep your purple shampoo regime to once a week, but get into a regular routine to keep warm tones at bay.

2: Alternate or mix in with a regular colour care shampoo to keep your hair colour vibrant and healthy.

3: Apply the Biolage ColorLast Purple Shampoo to wet hair, throughout the roots and ends, and lather.

4: Leave the purple shampoo to work in counteracting warm tones for 3-5 minutes before rinsing out thoroughly.

5: To keep your lightened hair soft, detangled and healthy, use a colour care conditioner, like Biolage ColorLast Conditioner.

6: Use a coloured or dark towel to pat your hair dry gently. The purple pigments can stain your towel but don’t worry, any residue colour will wash out.

7: When you’re not using your purple shampoo, always use an aftercare focused shampoo on lightened or bleached hair, like Biolage ColorLast Shampoo.
