The 'Ultra Color' line is designed for intense results. While it works on all hair textures, the vibrancy of Copper Passion 7.40 will be more pronounced on lighter hair. On very dark hair, the result may be a rich tone with copper undertones rather than a bright copper. Refer to the shade guide on the packaging for expected results on different starting shades.

The conditioner is enriched with 5 nourishing oils to help restore your hair, making it up to 3x shinier and up to 3x stronger. It also locks in moisture and helps maintain color vibrancy post-dyeing.

Immediately rinse the product off if symptoms occur. If you experience an allergic reaction, do not use the product again. Always perform the 48-hour skin allergy test before *every* application, even if you've used hair dye before.
