Purple shampoo vs blue shampoo: how to fix brassy hair, and when you need a toner instead

Summer sun, swimming pools and hard water all turn beautiful blondes and brunettes brassy. Here is how toning shampoo works, whether you need purple or blue, how to use it without turning your hair lilac, and the professional products that keep colour cool between salon visits.

Published 4 December 2026 by Lime Light Hair & Beauty Products.

Why does hair go brassy?

When hair is lightened, the bleach or lift colour breaks down the natural dark pigment in stages: from brown to red, then orange, then yellow, and finally pale yellow. The warm undertones left behind are what we call brass. A toner covers them up after colouring, but that cool tone slowly washes out.

Everyday life speeds this up:

• Sun and UV break down cool toner pigments.
• Chlorine and swimming pools strip colour and leave hair dry.
• Hard water and minerals build up on the hair and add a yellow or orange cast.
• Heat styling without protection fades colour faster.
• Strong shampoos wash toner out with every wash. A sulphate-free shampoo helps it last.

How does the colour wheel fix brassy hair?

Toning products work on a simple colour rule: colours opposite each other on the colour wheel cancel each other out. So the pigment you need depends on the brass you can see.

Purple shampoo vs blue shampoo: which do I need?

Look at your hair in natural daylight and ask: is it more yellow or more orange?

Does purple shampoo work on brown hair?

Only a little. Purple targets yellow, and lightened brown hair usually turns orange, so blue pigments do a better job. If your brunette has yellow-gold highlights, purple shampoo can still help those lighter pieces.

What is black or ash toning shampoo?

Black pigment shampoos, such as milk_shake Icy Blonde, are made for very light blonde, platinum and silver hair. They counteract warm yellow and orange reflects and push the colour towards a cool ash or icy silver finish. They are strong, so they are best for the lightest blondes.

How do I use purple shampoo properly?

1. Wet your hair well. If it is very dirty or full of product, wash first with your usual sulphate-free shampoo.
2. Apply evenly. Work the toning shampoo from roots to ends, focusing on the brassiest areas. Gloves help avoid purple fingertips.
3. Time it. Leave it on for 1 to 5 minutes. Start at the short end and build up as you see how your hair responds.
4. Rinse and condition. Follow with a toning conditioner or mask, or a moisture conditioner, as bleached hair needs hydration.
5. Repeat once or twice a week. Use your normal colour-safe shampoo on the other wash days.

When do I need a toner instead of a toning shampoo?

Toning shampoo is a maintenance product. It deposits a small amount of pigment with every wash. It cannot lift colour or make a big change. You need a salon toner or gloss when:

• The hair is strongly orange or yellow straight after lightening.
• The tone is uneven, with patches of different warmth.
• You want a specific shade, such as beige, pearl or champagne blonde.
• Toning shampoo is no longer keeping up between appointments.

Frequently asked questions

Can purple shampoo damage my hair?

No. It is a gentle shampoo with added pigment. The only risks are a temporary lilac tint or dryness if it is overused, which a normal wash and a good conditioner fix.

My hair turned purple. What do I do?

Do not panic. Wash once or twice with a clarifying or regular shampoo and the tint will fade quickly. Next time, leave the toning shampoo on for less time.

Can I use purple shampoo every day?

It is best not to. Once or twice a week keeps most blondes cool without dulling them.

Does purple shampoo work on grey and silver hair?

Yes. Grey and white hair often turns yellow from the sun, smoke and minerals, and purple shampoo brightens it back to a clean silver.

Can I use purple shampoo on dry hair?

Some people apply it to dry hair for a stronger effect, but it can be patchy and intense. Most stylists recommend wet hair and short timings.

Is blue shampoo the same as purple shampoo?

No. Blue pigment cancels orange tones on darker, lightened hair; purple pigment cancels yellow on blonde hair.
