You might stumble across an odd ad in a marketplace while you are checking marketplace app: blue and purple shampoo. You may wonder, what kind of shampoo is it? Will it turn one’s hair blue and purple like that character on a sci-fi movie? Well, don’t think that far as blue shampoo is used mainly to neutralize brass hair caused by warm hue of hair color, such as brunette and blonde. For your information, blue shampoo is usually used by brunettes, while purple shampoo is for typical blonde. However, is blue shampoo for blonde available?
What could be the science behind this? It is so simple that an elementary school kid can understand. The trick lies in color wheel theory. If you look at it, the color faces a certain color is called as its complementary. In the making of blue and purple shampoo, this easy-peasy theory is applied to the max. The purpose of this complementary color is legit: to cut down the overabundance of warm pigments (red, auburn (or orange), and yellow hues) coming with brunette and blonde hair color.
Now look back at the color wheel. Then, take a look at the red, orange, yellow area. Take an imaginary line connecting the color to its complementary color through to the circle’s center. You will see that for yellow, it links to purple. While orange, it stands across blue – meaning that blue is its complementary color. And that’s how blue and purple shampoo is ‘invented’. Blue shampoo isn’t commonly used for blonde. But if you insist, there is a limitation for that. Blue shampoo for blonde can only work effectively if your blonde is a type of darker blonde. If the color of your blonde is too light, it cannot work as expected. And the vice versa is also applied – purple shampoo does not work effectively to ‘neutralize’ brass brunette. You can use it to wash your hair still, but the effect once expected will not be achieved.
Who’s Eligible to Use Blue Shampoo?
Blue shampoo, just like its name, is a kind of shampoo that contains blue tint. Along with its ‘friend in crime’ – purple shampoo – they become a nice solution for brassy hair especially the one with dyed hair.

However, since there are a broad range of brunette and blonde in or surrounding, what kind of brunette is suitable for blue shampoo? What kind of blonde is perfect for blue shampoo? Can someone with natural brunette or blonde use it?
Well, it turns out that colorists, hair color manufacturers, and cosmetologists have this specific chart to standardize hair color.

So, you should not expect to see any colors beyond black, brown, and blonde hue.

To determine what your hair color is, it is best not to depend on people’s opinion. Pick a section of your hair then extend it away from the rest of your hair. You should also pick a section where it doesn’t get too much sunlight in typical day; therefore, it is advised to get a section far from the crown.

How to Use Blue Shampoo for Blonde?
Well, if you have a darker blonde (by birth or after getting a perm) and planning to add blue shampoo into your routine hair treatment, the how-to use blue shampoo for blonde isn’t much different. The important thing to highlight is, you don’t have to use it on a daily basis. Just like washing your hair with regular shampoo, it is unnecessary to use blue shampoo every day. Even if you want that brass-free and shining hair, using shampoo every day isn’t even a word.
The experts say it is safe to use the tinted shampoo once a week. There are also references mentioning that two times per week is alright too. But every day use has never been mentioned by anyone, mostly because too much blue shampoo may turn your hair darker than the shade desired. Plus, your hair will be dry.

- First, wet your hair just like when you want to wash your hair using your regular shampoo.
- Start applying the shampoo. Here is where the main difference between common shampoo and blue shampoo is located: where you mainly focus your blue shampoo at.

- After you apply the shampoo thoroughly, simply rinse it off until no shampoo is left.
- Following the blue shampoo, you should continue the treatment by applying conditioner – despite any types of your hair.
- As the last step, dry your hair. If you are accustomed to air dry your hair, make sure to protect your hair first by using heatspray. Make your hair in sections then spray onto it.
