FAQs

Do I still need an allergy test if I have used this product before?

Yes, a professional allergy alert test should be performed 48 hours before every single colouration process.

Can I mix this with developers from other brands?

For guaranteed results and to ensure the ME+ technology functions correctly, it is strongly recommended to use only Wella Welloxon Perfect Developer.

Is this product permanent?

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

Does 7/77 cover white or grey hair?

Yes, this formula is capable of providing up to 100% grey coverage.

What is the correct mixing ratio?

The mixing ratio is 1:1, meaning one part colour cream to one part developer.

Is this safe for all hair types?

Yes, it is suitable for all hair types, but a strand test is recommended to ensure the desired colour result on your specific hair history.

Troubleshooting

Colour looks patchy or uneven

Ensure that the hair was fully saturated during application and that you used enough product to cover all sections uniformly.

Grey hair is not fully covered

Check your mixing ratio and ensure the hair was not treated with heavy oils or silicones prior to application, which can act as a barrier.

Hair feels slightly dry after colouring

Use a deep conditioning treatment or a professional-grade post-colour hair mask to restore moisture balance.

Setup, Compatibility & Care

To achieve optimal results, you must mix one part of the Koleston Perfect 7/77 colour cream with one part of Wella Welloxon Perfect Developer. The mixture should be applied to clean, dry hair.

Compatibility: This product is designed for professional use and works best with the Wella Welloxon developer system. Always use non-metallic mixing bowls and brushes when preparing the dye.

Care: After the processing time, rinse the hair thoroughly until the water runs clear, then apply a suitable colour-protecting shampoo and conditioner to lock in the pigment and maintain the natural shine.
