FAQs

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

Yes. Even if you have used this product before, you must perform an allergy alert test 48 hours before every application as per the manufacturer's safety instructions.

Can I use a different brand of developer with this dye?

It is highly recommended to use Welloxon Perfect Developer to ensure the chemistry of the ME+ technology works correctly and to achieve the promised results.

What is the processing time for this color?

Processing times vary based on the desired level of lift and hair condition, but typically ranges from 30 to 45 minutes.

Is this product safe for pregnant women?

Please consult with your physician regarding the use of permanent hair color products during pregnancy.

How should I store unused dye?

Keep the tube tightly capped and store in a cool, dark environment. Once mixed with developer, the product must be used immediately and cannot be stored.

Troubleshooting

Color appears uneven after application

Ensure the product is thoroughly mixed with the developer and applied in small, uniform sections to guarantee full saturation.

Grey hair not fully covered

Verify that the mixing ratio is exactly 1:1 and check that sufficient processing time has elapsed for your specific hair texture.

Unexpected allergic reaction during the process

Stop application immediately, rinse hair and skin with lukewarm water, and seek medical attention if irritation persists.

Pros and Cons

Pros

  • Significantly reduced risk of allergic reaction compared to traditional formulas
  • Excellent grey coverage capabilities
  • Helps minimize hair damage through free radical neutralization
  • Produces deep, uniform, and long-lasting color results
  • Simple 1:1 mixing ratio streamlines the preparation process

Cons

  • Requires professional application for best results
  • Allergy alert test required 48 hours before every single use
  • Not intended for home users without prior coloring experience

Setup, Compatibility & Care

To prepare the color, use a non-metallic bowl and brush to mix one part Koleston Perfect with one part Welloxon Perfect Developer until the consistency is smooth and creamy. Ensure the hair is clean and free of heavy styling product buildup before application. Always wear professional gloves during the coloring process to protect your skin. After the development time is complete, rinse thoroughly until the water runs clear and follow up with a professional-grade color-locking shampoo or conditioner to seal the cuticle. For long-term maintenance, keep the tubes stored in a cool, dry place away from direct sunlight and ensure the cap is tightly sealed to prevent oxidation of the product inside the tube.
