FAQs
Do I really need to perform an allergy test every time?
Yes. Even if you have used this product before without issues, a mandatory allergy alert test must be performed 48 hours before every single color application.
Can I use a different developer brand with this dye?
For best performance and to ensure the ME+ technology functions as intended, it is recommended to use Wella Welloxon Perfect developer.
How much lift can I expect with this shade?
Depending on the developer used, this formula can provide between 3 and 5 levels of lift.
Is this product suitable for sensitive scalps?
While the ME+ technology reduces the risk of developing a new allergy, it is not a guarantee of safety for everyone. Always consult with a professional and perform a patch test.
What is the mixing ratio for this color?
The product uses a simple 1:1 ratio (one part color to one part developer).
Does this product work on dark hair?
Yes, but the final result will depend on your starting hair level. A 7/3 is a medium blonde shade; applying it to very dark hair may require pre-lightening.
Troubleshooting
Color appears darker than expected
Verify the developer volume used; using a developer that is too high or leaving the color on longer than the specified processing time can result in darker deposits.
Uneven color result
Ensure hair is thoroughly saturated during application. Check for adequate sectioning and avoid overlapping the product onto previously colored hair.
Insufficient gray coverage
Check the mixing ratio and ensure you are using the correct developer volume; check that the hair was not excessively coated in oils or styling products before application.

Setup, Compatibility & Care
To achieve professional results, ensure you use a non-metallic bowl and brush for mixing the 1:1 ratio. Mix one part Wella Koleston Perfect ME+ with one part Welloxon Perfect developer until the mixture is uniform.
Compatibility: This product is compatible with all hair types and is designed to work as a permanent color solution.
Care Instructions: Post-coloration, use shampoos and conditioners specifically designed for color-treated hair to maintain the gold vibrancy and shine. Avoid heat styling for the first 24-48 hours to allow the color cuticle to fully seal.
