Extended Product Information

FAQs

Do I need to mix this with a developer?

Yes, this product must be mixed with Welloxon Perfect developer at a 1:1 ratio.

Can I use this if I have had an allergic reaction to hair dye in the past?

No. ME+ technology reduces the risk of developing a NEW allergy, but it will not protect those who already have a known severe allergy to hair colorants.

How long does the color last?

As this is a permanent hair color, it is designed to last until the hair grows out or the color is cut off, though gradual fading may occur over many weeks.

Is this product suitable for all hair types?

Yes, it is formulated for all hair types, but results may vary depending on the underlying natural hair color and hair condition.

How do I perform an allergy alert test?

Apply a small amount of the mixed product to a small area of skin (usually inside the elbow) 48 hours before full application to check for any reaction.

Troubleshooting

Color result is lighter than expected

Check the developer volume used; higher volume developers provide more lift, which may shift the final shade.

Uneven color application

Ensure hair is saturated evenly during application and that sufficient product is used, especially on thick or long hair.

Staining on skin

Apply a barrier cream along the hairline and ears before application to prevent the dye from staining the skin.

Setup, Compatibility & Care

To use this product, mix 1 part Wella Koleston Perfect color with 1 part Welloxon Perfect developer. Always conduct a skin allergy test 48 hours before the actual application, even if you have colored your hair before. Ensure you are working in a well-ventilated area and wear appropriate gloves. Apply to dry, unwashed hair. After the recommended processing time, rinse the hair thoroughly until the water runs clear and follow up with a color-safe shampoo and conditioner to lock in the treatment and preserve the shine.
