Our products do not contain PPD.
Some of our products (our permanent colours) do contain an ingredient called toluene-2,5-diamine sulphate (also known as PTD).
PTD has a similar chemical structure to PPD and works in a similar way to activate the colouring pigments for permanent hair colour. There is some evidence to suggest that PTD causes fewer allergic reactions than PPD, but a small number of people can still experience a reaction to this ingredient and that is why it is very important to carry out an Allergy Alert Test 48 hours before using the product every time you colour your hair.
You will find information on how to carry out the test inside the pack and there is also lots of help available on our website.

If you notice any abnormal reactions during the Allergy Alert Test 48 hour period such as itching, redness or swelling in or around the test area DO NOT APPLY THE PRODUCT.
Our semi permanent root cover products and Glosses do not contain phenylene diamines. Please note our glosses are not designed to cover grey but instead designed to deep condition and give amazing tone. Our root touch up products are direct dyes that are designed to last up to 3 washes.
If you have any further questions please let us know.
