JOANNA PROFESSIONAL Cream oxidizer 6% 1000g

Hair colourants have been extensively studied and their safety has been repeatedly confirmed by independent scientists and regulatory authorities alike. Hair colourants themselves are regulated under the strict EU Cosmetics Regulation and are safe to use when the instructions are followed carefully.

HAIR COLOUR ALLERGIES
Reactions to hair colourants can occur for a very small number of people, in the same way that some individuals can react to a variety of foods and natural substances.

Allergic reactions to hair colourants are extremely rare. Of those individuals who have the potential to react to a hair colourant, potential reactions can be detected by carrying out the Allergy Alert Test, as directed, 48 hours before you wish to use the product. The Allergy Alert Test must be completed before each colour application, even if you have previously used the same hair colourant or the colourant of any other brand.

HOW TO TEST FOR ALLERGIES:

Remove Earrings
Behind the ear and using a cotton bud, apply a small quantity of unmixed colourant product sufficient to cover an area of 1-2cm² (e.g. the size of a small coin).

Re-apply
Re-apply two or three times allowing it to dry between each application. Carefully reseal the colourant container and keep it for the application 48 hours later.

48 Hours
Leave for 48 hours without washing, covering or touching.

Reactions
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.
