If you're blonde, you've probably heard of violet shampoo . This product is so essential in the care routine of those who have light hair (natural or colored, it doesn't matter) became famous for helping to eliminate the yellow tones of the threads.

Blue or violet shampoo, that's the question
The first step in understanding blue shampoo is to remember that your hair is not just one color, but a mixture of shades that together form the nuance you see. The base color of blonde hair is yellow, which becomes more and more apparent as the surface tones fade over time. It is the so famous (and unwanted by most blondes) yellowish hue. This is where the violet shampoo comes in: the color manages to neutralize the hair's yellowish tone , leaving the blonde strands more luminous and with a more lively nuance again.
But why violet and not other colors like green or red? Violet is used in contrast to yellow because of the so-called Oswald Star, a model within colorimetry (the science that studies colors) that displays in a simplified way primary, secondary, cold, warm, their mixtures and, of course, opposites. .
For this reason, violet shampoo is used to neutralize the yellow tones of blonde hair. And with the blue shampoo the idea is exactly the same, only to neutralize a different color: orange. “The composition and agents change, but the purpose is similar to violet”, confirms Adriano Almeida, a trichologist from São Paulo and director of the Brazilian Hair Society.

Due to external aggressions (read humidity, wind, sun and pollution), previous colorings or even the combination of different hair products, your blonde can take on more intense shades of orange or copper instead of yellow. “If the hair turned orange or coppery , the blue shampoo is the most indicated to neutralize this color”, says dermatologist Livia Pino, from Rio de Janeiro.
Your blond hair turned yellow after coloring and you only have blue shampoo at home. Is the effect the same? According to the expert, it is better not. “If you use blue shampoo in this case, the hair will 'pull' to gray ”, he says. In other words, every problem with your exact shampoo color.
Another important issue for both blue shampoo and violet shampoo is the frequency of use, which generally should not go beyond once a week. “Usually these shampoos can dry out the hair. But each case must be individually evaluated by a trained professional”, Livia warns.
