It's important to perform an Allergy Alert Test each time you colour your hair, even if you’ve used at home hair dye before and had no reaction, as skin can develop an allergy over time.
An allergic reaction can consist of itchy skin, redness or even blisters on your scalp, so it’s really important to do an Allergy Alert (Patch) Test to avoid these. DO NOT use the product if you experience any reaction.
Follow these simple steps 48 hours prior to applying colour to your hair:
1) Mix a coin-sized amount of the colour formula (A) and activator (B), plus the same sized amount of the Shade Shot (if adding for a personalised finish) and mix together in a bowl.
Tip: It’s very important to fasten the caps on the bottles tightly after you have opened them for the Allergy Alert Test, to prevent the products oxidising and ensure the active ingredients will work after the test.
2) Use a cotton bud to apply a small amount behind your ear. Or use a cotton wool pad wrapped around the pointed tip of the colour brush in our Accessories Kit.
3) Dispose of leftover product down the sink, with running water. Leave the water running slightly longer after disposing of contents to ensure all product has gone.
4) Leave it on for 48 hours before washing off. You shouldn’t even notice it’s there.
If you have any signs of reaction, wash it off immediately and do not use the permanent colour. Please do contact us at firstname.lastname@example.org if this is the case and we will happily refund you for the product.
If you show no signs of reaction to the dye, it is your all clear to go ahead and use your perfect shade match as instructed.
