How Often Should You Use Blue Shampoo? Like its purple cousin, blue shampoo isn't designed for everyday use. Instead, you can use it once a week as part of your existing haircare routine. This will prevent build up and your hair being left looking too dark or muddy.
As such, try to swap a blue shampoo into your routine about once a week to reap its benefits without risking discoloration. If you go overboard, you can use a clarifying shampoo to help remove unwanted pigment.
Using blue shampoo once or twice a week is definitely enough to tone down brassy hair and add moisture. You don't have to give up on washing your hair completely, just choose one of Aussie's regular shampoos that best fits your needs as part of your regular brunette toning routine.
Unless the shampoo is specifically designed to be used as a daily toner, applying purple shampoo every time you wash your hair is typically discouraged because it can begin to eliminate too much yellow from your hair.
No, it's not okay to leave blue shampoo in your hair for too long. It makes the yellow in your hair look more yellow and it's overused. It's not something that everyone needs all the time.
Shampooing once or twice a week with blue shampoo should be enough to keep any orange or red tones from showing through. If you need to wash in the meantime, use a nourishing, color-safe shampoo like our anti-frizz shampoo to keep your locks soft and healthy-looking.
The longevity of blue hair dye varies depending on several factors, including the shade, your hair's porosity, and your hair care routine. On average, blue hair dye can last between 4 to 8 weeks, but it may fade gradually over time.
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.
Keep in mind that purple shampoo does not replace your regular shampoo and should only be used once or twice a week. Doss warns that there is such a thing as too much purple. “When you eliminate too much yellow, it visually ends up darker and a lot of people don't want it to look darker,” she says.
Orange is opposite blue on the color wheel. This means blue cancels out orange. If you've got dark hair with balayage, ombré or conventional highlights, if you've lightened your dark hair completely, or if you have a combination of dark and light hair with highlights, blue shampoo is your solution for brassiness.
If your hair is resistant to color, using blue shampoo on dry hair may be more effective. If your hair takes color well, do a strand test on dry hair. If you rinse it out and end up with unwanted blue tones, you may be better off applying the shampoo to wet hair in the future.
The former isn't supposed to replace your regular haircare products—it's supposed to merely supplement them, so stick to using these products only once or twice a week, and only when you see the orange undertones emerge. Always follow up your blue shampoo with a conditioner that moisturizes your hair sufficiently.
Neutralizes brassy tones in all shades and adds silvery brightness to gray hair.
If you leave purple shampoo in your hair for 30 minutes, the risk of over-toning increases significantly. While purple shampoo is designed to neutralize brassy or yellow tones, leaving it on for an extended period can lead to overly cool or even purple-tinted hair, especially for those with light or porous hair.
But there's more to it than that – it's actually a type of hair toner that helps neutralize or enhance certain undertones in your color. Blue shampoo is typically used for brown hair, as it combats the kind of orange, red, and copper undertones that make brunette hair look brassy.
If you're a darker blonde with orange tones, blue shampoo neutralises orange tones within blonde hair, banishing brassiness. Perfect for brunettes turned blonde converts, whether you've gone ombre, balayage, highlights or gone all the way.
Like its purple cousin, blue shampoo isn't designed for everyday use. Instead, you can use it once a week as part of your existing haircare routine. This will prevent build up and your hair being left looking too dark or muddy.
If you've wondered whether you can use purple shampoo every day, the answer is generally no. Purple shampoo is most effective if used as needed to reduce visible brass.
USE & TIPS. Gently massage blue shampoo into wet hair. Lather and rinse well. For more intense results, and to fight brassiness in brown hair, leave shampoo on your hair for 2-3 minutes.

Blue toning formulas can help counteract orange tones in the hair. The reasoning goes back to basic color theory: Shades positioned opposite on the color wheel are complementary and effectively cancel each other out when combined.
If you have never toned your hair before, it's best to do a strand test first as the results of the treatment will vary depending on your hair's porosity. Leave the toner in for between 5-20 minutes: you can rinse a small section to see when the color has fixed to your liking.
