HIGH TOLERABILITY AND PERFORMANCE
The Permanent Hair Colour Gel offers high tolerability thanks to the test on sensitive skin.
However, it is always recommended to perform a sensitivity test 48 hours before each use of the product, even if a hair colouring product has been used before.
Get a bandage and a cotton swab. Soak the bandage with a small amount of colour and developer. You can use the two ends of the cotton swab to collect the two liquids. Do not use metallic objects. Seal the bottles tightly.
Apply the bandage with a small amount of mixture to the forearm area or behind the ear and do not remove it. After 45 minutes, rinse and pat the area dry with a clean tissue. If you notice itching, redness or swelling above and around the test area within the next 48 hours, rinse and do not use the product. Consult a doctor if necessary. This test is an important precautionary measure that has proven reliable when the provided instructions are strictly followed. However, the sensitivity test does not guarantee that allergic reactions will not occur in the future. If you have any doubts or questions, consult a doctor.
