Eight ways to stop your hair turning yellow

You left the salon with the most beautiful shade of blonde, which took ages to do, and you’re delighted with the result. But hang on … is that yellow you see? It can’t be more than two weeks since it was done, so why, why, why is it changing colour?

We understand that you’re annoyed that your colour is changing, but unfortunately that’s just the nature of hair – even a permanent colour will fade, change and be washed out of the hair. How much your colour changes is affected by two things: the condition of your hair and the products that are used to colour your hair and then to maintain that colour.

The number and range of products in hairdressing is huge and confusing, and you are bombarded with them from every direction. Why do I care? Because I want to make sure that you love your hair. xx


When you go blonde, the colour inside the hair is revealed. This always has a yellow tinge, but when your hairdresser uses a toner it neutralises and cools down that warmth. However, this toner generally washes out of the hair with each shampoo. So, if you want to stay a cool blonde for any length of time there are eight things you need to take a look at:

  • What shampoo will stop my hair turning yellow?
  • What conditioner will stop my hair turning yellow?
  • Do I need to use a heat protector on my hair?
  • Can I use a toner at home?
  • What temperature should my dryer/irons be?
  • Will bonding treatments stop my hair going yellow?
  • Will a treatment stop my hair going yellow?
  • Take your stylist’s advice.

1.What shampoo will stop my hair turning yellow?

Purple shampoo is used especially for neutralising yellow tones. Purple sits opposite yellow on the colour star, so the stronger the tone of purple/violet the more yellow will be eliminated from your hair. If you want to keep your hair’s ash colour then you really need to use a purple product.  However, for some people, purple shampoo isn’t great for condition – if you’ve tried some and it didn’t suit your hair type, then choose a shampoo for coloured hair instead. These are designed to protect your colour when you shampoo, keeping it in the hair longer.

2. What conditioner will stop my hair turning yellow?

Another product you can use is a purple conditioner or treatment. As with shampoo this has a built-in purple pigment but unlike a shampoo, which is designed to clean, a conditioner will help leave your hair in better condition, looking less yellow and feeling great, too.

3. Do I need to use a heat protector on my hair?

The heat from your dryer opens the hair cuticles and lets the colour out, which will change the look of your colour. By using a heat protector you put a barrier between the heat and your hair, preventing this from happening.

4. Can I use a toner at home?

A toner will last for around 14 or so washes, depending on the brand and strength. Ask your hairdresser what they have in stock, as this will be better than you trying things out at home. There are many available in shops, but do be careful as it may not be the colour you’re looking for  – the tone can be strong, and although you may want purple or grey looking hair it can be a bit of a shock if this wasn’t the look you were looking for.

5. What temperature should my dryer/irons be?

The hotter your electricals, the faster you will lose the colour in your hair. The heat opens cuticles, leaving the hair open to damage, which can quickly change the look of your colour. So turn down the heat and the speed. It’s better to take a bit longer drying and straightening your hair that to blast the goodness out of your hair.

TIP:  The best way to remove moisture from your hair is to wrap a towel round your head for a good ten minutes. Once that’s done your hair should be feeling a bit less wet. Then comb out your hair or, better still, use a Tangle Teezer. Give it a quick blast, then reduce the heat and slow down the dryer.

6. Will bonding treatments stop my hair going yellow?

Bonding treatments are the big new thing: Olaplex, Fibreplex and Bond Ultim8 are just a few of the brands available. They are designed to strengthen the bonds that are weak and prevent further breakage in the hair. The more bonds in the hair for the colour molecules to attach themselves to, the better. Again, the better your hair condition, the longer your colour will last.

7. Will a treatment stop my hair going yellow?

Treatments do a different job to a bonding treatment as they help to strengthen, nourish and re-hydrate the hair.

The more you do to your hair the more moisture and strength it will lose, and its condition will slowly deteriorate. To maintain healthy hair and avoid damage you need to replace the moisture and restore the strength, otherwise the colour will wash straight out.

For dry, dehydrated hair you need restore moisture for the hair to keep its elasticity, and for brittle, easily broken hair you need to build its strength – some people’s hair needs both.

My advice is to have a weekly treatment to keep your coloured hair in great condition and slow down any colour changes.

8.Take your stylist’s advice
