Can I use any remaining Tints of Nature Permanent Colour for my next application?

Yes and no. If left unmixed and in their original bottles the colour gel and colour fix can last up to 6 months from the opening date. However, if the colour gel and colour fix are mixed, the solution will only last for one hour due to the oxidisation process.

Please be aware we recommend storing the left-over bottles in a dry place out of direct sunlight.
