Eliminate coppery tones and restore cool elegance to your brunette or dark hair!
Karseell Blue Hair Mask has been specially formulated to neutralize the orange and copper tones that commonly appear in brown, dark hair, or chocolate balayage highlights. Unlike the Purple Mask (which targets yellow tones), the blue pigment is uniquely capable of cancelling unwanted orange oxidation tones. In addition to correcting color, its professional formula deeply hydrates and helps repair damaged hair.

- Glove use: Wearing gloves is important, as the blue pigment is highly concentrated and may stain hands and nails.
- Apply evenly from mid-lengths to ends.
- Processing time: 3–5 minutes for light neutralization and maintenance of cool tones. 10–15 minutes for intense neutralization of strong coppery reflections.
- Rinse thoroughly with plenty of water.
Frequently Asked Questions
What is the difference between the Purple Mask and the Blue Mask?
The Purple Mask is designed for blondes and grey hair (neutralizes yellow tones). The Blue Mask is designed for brunettes and dark hair (neutralizes orange and copper tones). If you have orange highlights, the Blue Mask is the best option.
Can it be used on very light blonde hair?
It is not recommended for very light or platinum blonde hair, as the blue pigment may leave a greenish cast. For those shades, the Purple Mask is the better choice.
Does it stain the bathroom?
Because it contains a strong pigment, it is recommended to rinse the shower or sink thoroughly after use to prevent persistent stains.
How do I know it is the original product?
On our official website, we guarantee authenticity. The original product has a dense consistency and an intense indigo-blue color that ensures color correction from the very first application.
