You might want to turn to blue shampoo if your hair is turning a brassy orange. A simple wash can really turn back the time on your gorgeous, coloured hair.

Blue shampoos are typically used to neutralise brassiness in brown hair, since blue is opposite to orange on the colour wheel.

Whether you have brown hair or caramel-coloured highlights, a blue shampoo may be just what you need to eliminate those orange hues.

In this article, we’ll be sharing the differences between blue shampoo and purple shampoo. You can also expect a few before-and-after photos as well as a list of the best blue shampoos for brassy hair.

If you’ve heard of colour toning shampoos, you might have seen purple shampoos and wondered how it differs from a blue shampoo.

Purple shampoo is used to eliminate the yellow colours that can surface in blonde hair. This works because purple is the opposite of yellow on the colour wheel, similar to how blue is the opposite of orange.

After identifying the undertones you want to eliminate, it is easy to choose between blue shampoo and purple shampoo. In fact, we’ve even got a list of best purple shampoos if you want to maintain your blonde hair.

Adding blue shampoo into your regular shower routine is a very simple process. You just need to use it a few times a month or at most every other time you wash your hair.

Here are the steps to use a blue shampoo:

  1. Wear some gloves to save your nails from being stained blue.
  2. Wet your hair and massage the blue shampoo in. Try to apply it as evenly as possible from root to tip.
  3. Allow the shampoo to sit according to product instructions. Usually, the longer it sits, the more it will work. (But don’t leave it on too long, as you can end up with blue strands!)
  4. Rinse off the blue shampoo and follow up with your usual conditioner and other haircare products.
  5. Admire your brass-free hair in the mirror and enjoy those beautiful tresses.

Here are a few before and after photos of how blue shampoo can really help to get rid of those brassy tones. You’ll also be able to get a better idea of what you can look forward to.
