This is a permanent hair dye, meaning the color is designed to be long-lasting. As your hair grows, you will need to reapply to cover new root growth.

Yes, a skin allergy patch test is mandatory and must be performed 48 hours before each and every use of this product, even if you have used hair colorants before. Allergies can develop suddenly.

Each pack typically includes: 1x colouring cream, 1x developer cream, 1x Caring Gentle pH Post-Colour Shampoo, 1x Caring Lightweight Mask (conditioner), and 1x pair of protective gloves.

ReflectU technology is designed to help achieve natural and easily achievable hair color results that complement your existing tones, preventing a flat or artificial appearance.

This product can be used on previously colored hair. However, the final shade may vary depending on the existing color and condition of your hair. Always refer to the shade guide provided in the box.

Ensure you followed the processing time accurately. Your original hair color and condition significantly impact the final result; consult the shade guide on the box. Inadequate saturation during application can also lead to uneven results. If hair was previously colored, this could also affect the outcome.

Ensure the product was applied thoroughly and evenly to all grey areas, especially stubborn ones around the temples or hairline. Verify that the correct processing time was observed. For very resistant greys, ensure adequate product saturation.

Immediately after coloring, use the entire amount of the provided `Caring Lightweight Mask` (conditioner) for deep nourishment. For ongoing care, incorporate a weekly deep conditioning treatment or hair mask. The ammonia-free formula is designed to be gentle, but external factors like heat styling or sun exposure can contribute to dryness.

Immediately rinse the product from your hair and scalp. This highlights the absolute necessity of the 48-hour patch test. If irritation persists, seek medical advice. Do not re-apply the product if an allergic reaction is suspected.

Ensure you thoroughly shook the developer bottle after adding the colouring cream for at least 60 seconds until the mixture is uniform. If the mixture still appears incorrect, it's best not to proceed and consult the manufacturer or discard the product.
