What Is Blue Shampoo?
Blue shampoo, also known as blue toning shampoo, is a color-depositing shampoo formulated with blue pigments. Its primary purpose is to neutralize orange, red, and brassy tones that can develop in brunette or dark-colored hair over time. These unwanted tones often result from factors such as sun exposure, heat styling, and the natural fading of hair color between salon visits.
The science behind blue shampoo is rooted in color theory. On the color wheel, blue sits opposite orange. This means that blue can cancel out or neutralize orange tones, much like how purple shampoo is used to neutralize yellow tones in blonde hair. By incorporating blue shampoo into your hair care routine, you can maintain a cooler, more balanced hair color and prevent brassiness from taking over.
Why Do You Need Blue Shampoo?
Brunettes and those with dark hair, whether natural or color-treated, are prone to developing warm, brassy tones as their hair color fades. This can happen for several reasons:
- Sun Exposure: UV rays from the sun can cause your hair color to oxidize, leading to the appearance of warmer tones.
- Heat Styling: Frequent use of hot tools like straighteners, curling irons, and blow dryers can contribute to color fading and the emergence of brassy hues.
- Water Quality: Hard water, which contains high levels of minerals, can deposit these minerals onto your hair, leading to color changes over time.
- Chemical Treatments: Color treatments, especially those involving bleach or lightening agents, can alter the natural undertones of your hair, making brassiness more likely.
Blue shampoo addresses these issues by depositing cool blue pigments onto your hair, effectively neutralizing the warm tones and restoring your color to a more desirable shade. This is especially beneficial for those with highlights, balayage, or ombre styles, as these techniques often involve lightening certain sections of the hair, making them more susceptible to brassiness.
How to Use Blue Shampoo
Using blue shampoo correctly is crucial to achieving the best results. Here’s a step-by-step guide on how to use blue toning shampoo effectively:
- Start with Damp Hair
Blue shampoo should be applied to damp hair, not soaking wet. Start by thoroughly wetting your hair in the shower, then gently squeeze out the excess water. Damp hair will allow the blue pigments to distribute more evenly.
- Apply the Shampoo Evenly
Dispense a generous amount of blue shampoo into your hands and work it into your hair, starting at the roots and working your way to the ends. Be sure to focus on areas that are most prone to brassiness, such as the mid-lengths and ends, as these are often the sections that have been lightened or colored.
- Leave It On
The amount of time you should leave blue shampoo on your hair depends on the level of toning you need. For subtle toning, leave the shampoo on for 2-3 minutes. If your hair is particularly brassy or you want a more intense toning effect, leave it on for up to 5 minutes. However, it’s essential to follow the instructions on the product packaging, as leaving it on too long can result in an ashy or overly cool tone.
- Rinse Thoroughly
Once the desired time has passed, rinse your hair thoroughly with cool or lukewarm water. This helps to close the hair cuticle, locking in the pigments and sealing in moisture. Make sure to rinse until the water runs clear, as any leftover product can weigh down your hair or leave a bluish tint.
- Condition Your Hair
After rinsing out the blue shampoo, follow up with a conditioner. If you have a blue toning conditioner, even better! Conditioning helps to restore moisture to your hair, leaving it soft and manageable. Focus the conditioner on the mid-lengths and ends, where your hair is most prone to dryness.
- Style as Usual
Once you’ve completed your blue shampoo routine, you can style your hair as usual. You should notice a difference in the tone and vibrancy of your hair, with brassiness significantly reduced and your color looking fresher and cooler.
How Often Should You Use Blue Shampoo?
The frequency with which you use blue shampoo will depend on your hair type, color, and the specific product you’re using. For most people, using blue shampoo once or twice a week is sufficient to maintain their desired tone. However, if your hair is particularly prone to brassiness or you’re trying to correct an overly warm tone, you may need to use it more frequently.
It's essential to monitor your hair's response to blue shampoo. Overuse can lead to an overly cool or ashy tone, which might not be the look you’re aiming for. If you notice your hair becoming too cool or losing its natural warmth, reduce the frequency of use or alternate with a regular, non-toning shampoo.
