The following precautions must be adhered to before using any hair colourant.
Do not use if you have already had a reaction to a hair colourant or if you have a sensitive, itchy or damaged scalp.
Every time you colour your hair it is important to carry out an Allergy Alert Test 48 hours beforehand.
Behind the ear and using a cotton bud, apply small quantity of the unmixed colourant product sufficient to cover an area of 1 to 2 cm2 (e.g. the size of a small coin).
Re-apply two or three times allowing it to dry between each application.
Carefully reseal the colourant container and keep it for the application 48hrs later.
Leave for 48 hours without washing, covering or touching.
If during this period you notice any abnormal reactions – such as itching, redness or swelling in or around the test area, DO NOT APPLY THE PRODUCT
Remember, when using hair colourants, always Be Colour Safe.
