Question 1

Why does blonde hair turn brassy and yellow?

Accepted Answer

It’s to do with colour chemistry. During the colouring process, hair is bleached and the natural pigment is removed or diluted. Any new colour that’s deposited gets gradually washed out, leaving brassy tones.

During the bleaching process, hair becomes more porous. Porous hair soaks up the metals and minerals in water, as well as pollutants, such as smoke and grime, from the environment. In time, these elements turn blonde hair yellow and brassy.

Also, blonde hair absorbs light instead of reflecting it, which makes it even more prone to damage that makes hair yellow and dull.

These factors all make bleached and coloured hair more likely to turn brassy and yellow.

Question 2

What does purple shampoo do to your hair?

Accepted Answer

The shampoo enhances blonde or lightened hair, as well as natural grey and white hair. It contains purple or violet pigments that colour-correct brassy tones to restore the former cool colour.

If you have blonde, silver or grey hair that tends to turn yellow, purple shampoo is your new best friend.

Question 3

How does purple shampoo work?

Accepted Answer

Purple shampoo removes yellow tones through a simple but very clever process. Yellow and purple are opposite each other on the colour wheel, which means they cancel each other out.

When you wash your hair with shampoo that contains purple or violet pigments, the pigment is deposited in the hair and yellowy tones are neutralised.

Question 4

Can you leave purple shampoo overnight?

Accepted Answer

No. To get the best results, follow the instructions on the shampoo bottle.

Usually, the recommendation is to massage the shampoo into wet hair and leave it on for three to five minutes. Depending on your hair type and the result, you may want to leave it longer or less next time you shampoo your hair.

If you leave the shampoo on for too long, it might add a lavender tinge to your hair. It's also more likely to have a drying effect.

Question 5

Can you use the shampoo daily?

Accepted Answer

We recommend starting to use the shampoo once a week and building up as needed, depending on your hair type, its condition and colour. Alternate with a colour-safe shampoo like Osmo Colour Save Shampoo.

Question 6

Why is purple shampoo good for blonde hair?

Accepted Answer

The shampoo provides a fast, easy and affordable way to maintain cool blonde hair colours in between salon visits.

Make it a regular part of your hair-care routine so your hair colour stays fresh and cool-toned.

Question 7

What’s the difference between purple and silver shampoo?

Accepted Answer

Silver shampoo doesn’t look silver. It’s also purple or violet.

All purple, silver, violet and blue shampoos work to neutralise brassiness and maintain colour by depositing purply-coloured pigment.

The shampoo you choose should depend on your hair and the colour you want. You may choose silver shampoo if want to maintain a cool, platinum shade in your grey, silver or blonde hair.

Question 8

Does purple shampoo dry out hair?

Accepted Answer

If your hair is porous, some purple shampoos can be drying. Always use a professional-quality shampoo and conditioner.

Sulphates give shampoo that foamy lather and help lift oil from your scalp, but they can also accelerate drying and fading. Choose a purple shampoo that’s sulphate free if you have dry hair.

Follow with a hair mask. Masks are intensely hydrating and replenish lost moisture while neutralising yellow tones.

Try the Perfect Blonde Trio from Pravana. You get a shampoo, conditioner and mask in one.

Question 9

Does purple shampoo break your hair?

Accepted Answer

The shampoo is formulated to return yellow and brassy to cool, blonde tones. If used correctly and with a conditioner and mask, it won’t break your hair.

However, if your hair is very dry and damaged and you use purple shampoo incorrectly, it can leave buildup on your hair that can make strands brittle, dull and prone to breakage.

Question 10

Can purple shampoo cause hair loss?

Accepted Answer

Purple shampoo doesn’t cause hair loss. If you have very bleached, damaged hair and overuse purple shampoo – using it too frequently or leaving it on too long – it could lead to hair breakage that looks like hair loss.
