FAQs

Do I really need to do an allergy test every time?

Yes, even if you have used the product before, you must perform an allergy alert test 48 hours prior to each application to rule out any potential reactions.

Can I use any developer with this hair color?

It is highly recommended to use Wella Welloxon Perfect Developer to ensure the formula performs as intended and provides the best color results.

Is this product permanent?

Yes, Wella Koleston Perfect ME+ is a permanent hair colorant designed for long-lasting results.

Does it contain ammonia?

Koleston Perfect is a professional permanent cream color; please check the specific ingredient list on the box for ammonia content if you have sensitivities.

How much developer do I need to add?

The mixing ratio is 1:1. For every 60ml of color, use 60ml of developer.

Can I use this if I have had an allergic reaction to hair dye before?

No. The ME+ technology is for people who are not allergic to hair colorants. If you have previously experienced an allergic reaction to permanent hair dyes, do not use this product.

Troubleshooting

Color result is uneven

Ensure hair was evenly saturated during application and check that the mixing ratio was exactly 1:1.

Poor grey coverage

Verify that you have not diluted the color too much and ensure the processing time is sufficient for resistant grey hair.

Hair feels dry after coloring

Ensure you are using the correct developer volume; using a developer that is too high can cause unnecessary dryness.

Setup, Compatibility & Care

To prepare the product, ensure you are using a non-metallic bowl and brush for mixing to prevent chemical interference. Always mix the color with the recommended Welloxon Perfect Developer at a 1:1 ratio. For care after coloring, use color-safe shampoos and conditioners to maintain the integrity of the pigment and preserve the shine. The product is compatible with all hair types, but users should always conduct a strand test to determine the exact processing time required for their specific hair porosity and color history. Store the tube in a cool, dry place away from direct sunlight, and ensure the cap is tightly secured after each use to prevent oxidation.
