It seems that as soon as we leave the salon with dyed hair, the eternal battle begins: the color starts to fade and those unwanted tones that we don't like at all appear. Fortunately, there is a solution: shampoos with blue and purple pigments, irreplaceable allies in preserving the color until the next appointment at the hairdresser.
But which one should we choose?
The secret lies in color theory. On the color wheel, purple is opposite yellow, and blue is opposite orange. This means that:
Purple shampoo neutralizes yellow tones.
Blue shampoo counteracts orange or bronze tones.
Purple shampoo
If you have dyed blonde hair, it's normal for unwanted yellow tones to appear after a few weeks. Purple shampoo is the perfect solution for this. When washed, it releases a light purple pigment that helps neutralize yellow, giving your hair a cleaner, fresher, and cooler look.
Blue shampoo
For those of us with brown, chestnut, copper, and balayage hair, blue shampoo is the best choice. It helps to soften the orange or bronze tones that often appear after a few washes, while maintaining a more balanced and elegant color.
How to use them without damaging your hair
To avoid drying out or over-pigmentation, it's a good idea to alternate blue/purple shampoo with your regular shampoo, or mix them together. This helps to maintain hair moisture and prevents unwanted color changes.
