    Hi Suzi,

    The shelf life of all our unopened hair colourants is 3 years from the date of manufacture. We would recommend using the product within this time in order to achieve the best results. After this time, the product may still be effective; but please ensure that you do a Strand and Sensitivity Test as normal.

    You can find the manufacturing date from the Production Code: Look at the first 4 numbers of the production code. The first number represents the year of manufacture, the next 3 digits represent the exact day of manufacture. (The letters in the code are not relevant to the date of manufacture). So if the production code was 93303725C2, the product would have been manufactured on the 330th day of 2009, so still within the 3 year shelf life.

  • I know you can use it up to 3 years but what would happen if it has been on the shelf for longer?
