Purple or blue shampoo: a guide to choosing the right one for your hair color

You’ve invested in a beautiful hair color, but a few weeks later, your highlights turn yellow or orange. This inconvenience affects many people with blond, gray or highlighted hair. Fortunately, a pigmented shampoo can neutralize these undesirable hues and revive theradiance of your color.

Violet or blue: understanding the difference between these pigmented skincare products

The key to choosing the right product lies in color theory. On the color wheel, opposite hues cancel each other out. Thus, violet neutralizes yellow, while blue combats orange reflections.

Your hair base therefore determines the right treatment for your needs. Hair that is naturally blond or bleached to a very light shade tends to turn yellow over time. On the other hand, brunettes who lighten their hair often see coppery tones emerge.

This phenomenon can be explained by the oxidation of pigments and the action of sunlight, chlorine or pollution. Identifying the nature of your unwanted highlights is therefore the first step before any purchase.

“Violet and blue don’t do the same job: one dejaunifies, the other decolors.”

Who should use purple shampoo?

This treatment is particularly suitable for polar, platinum or ash blondes. It also works on gray or white hair that turns yellow over time. In addition, very light highlights benefit from its neutralizing action.

The violet formula deposits cool pigments directly on the hair fiber. It doesn’t modify color deep down, but corrects surface nuances. The result is a fresh, luminous blond in just a few applications.

Foamie – Dejaunting Solid Shampoo (€5.95) offers a practical, economical alternative for maintaining your cool highlights on a daily basis, without weighing your hair down.

• Platinum or polar blondes with yellow highlights
• Grey or white hair dulled by time
• Light sweeps that lose their shine
• Bleached highlights turning golden
• Regular maintenance for cool colorations

Blue care: the solution for orange highlights

Brunettes who go blond know all about this problem. Their dark base contains warm pigments that stand out during fading. These copper or red highlights can ruin the desired result.

Blue Shampoo precisely targets these undesirable shades. Its formula, rich in cool pigments, neutralizes orange and copper. The result is a more even, natural-looking blond.

This product is also suitable for lightened chestnut or ombré hair. It also works on caramel colorations that turn red. Its action remains gentle, but effective on medium to dark tones.

Be careful, however, not to use it too often. Excessive use can dull hair or deposit too much pigment. Once or twice a week is generally sufficient for optimal maintenance.

How do I use these pigmented skincare products?

Application technique has a major influence on the final result. Start by wetting your hair, then apply the product to lengths and ends. Gently massage in for two to five minutes, depending on the desired intensity.

Never exceed the exposure time recommended on the packaging. Too much pigment can cause visible violet or bluish highlights. Rinse thoroughly with lukewarm water to remove any residue.

Alternate with a classic moisturizer to keep your hair healthy. These pigmented formulas can dry out the fiber over the long term. A nourishing mask is the perfect complement to your hair routine.

Common mistakes to avoid

Many people choose the wrong product out of ignorance. Using a violet skincare product on orange highlights will not produce convincing results. Similarly, blue won’t work on pale yellows.

Another common mistake is to apply these formulas to dry or damaged hair. The porosity of the hair causes too much pigment to be absorbed, creating stains. Always moisturize your hair before adding these products to your routine.

Some users leave the product on too long, hoping for a better effect. This practice, however, runs the risk of visibly coloring even the most porous strands. Patience and consistency are your best allies for a harmonious result.

Finally, don’t forget to protect your hands with gloves during application. Pigments stain skin and nails very easily. This simple precaution will prevent stubborn stains for several days.
