Blue vs Purple Shampoo: What’s the Difference

Before we answer this question, it’s important to note that all different hair colors present different undertones. Brunette hair typically produces warmer orange undertones, while those with very dark hair can have red undertones. As for blondes and others with light hair color, yellow undertones are what’s present. When these warm undertones start to appear in blonde hair, whether it’s due to color treatment, hair products, or heat styling, it’s referred to as brassiness.

To get rid of this unwanted brassiness, you’ll need to tone it down with the opposite, or complementary, color. If you think of the color wheel you first saw in elementary school, blue falls on the opposite side of the spectrum as orange. In contrast, purple sits across the color wheel from yellow. If you are wondering, “what does blue shampoo do?” and “what does purple shampoo do?” – this is it. The blue pigment cancels out orange, and the purple pigment cancels out yellow.

All this talk about color comes down to two important points. Blue shampoo removes orange tones from brunette or darker hair, while the purple shampoo is a great option when yellow tones appear in blonde or light-colored hair.

Blue shampoo vs purple shampoo: what are the benefits?

The biggest benefit of both blue shampoo and purple shampoo is the ability to neutralize unwanted yellow or orange tones at home with a toning shampoo. 

Maintains color longer

Rather than stopping into the salon more frequently to keep your hair color looking its best, you can help maintain your color just by washing your hair. This is great news for both bright blondes and brilliant brunettes.

Ensures shine + luster

Helping your color last longer isn’t the only advantage of blue and purple shampoos. They can also help with maintaining your hair’s natural shine and luster, again without having to stop by the salon for special treatments.

Saves you expensive trips to the salon 

One final benefit of blue shampoo and purple shampoo is that they can help you save time and money. They can reduce the number of trips you make to the salon by helping you maintain your hair color longer. Think of it as having the best of both worlds.
