ALLERGY ALERT TEST: Items you need to prepare the mixture: Cotton bud, clean tissues, saucer / small plate (do not use metal objects). Prepare the mixture: With a cotton bud, mix small amounts of colorant agent and developer of the same quantity on a saucer/small plate. With the cotton bud, apply a pea size of the mixture evenly with a thin layer on an area of 1 by 1 in. on the inner side of the forearm. Leave the mixture applied for 45 minutes without covering or touching it; avoid contact with clothes; after 45 minutes wash the test area with water and pat dry with a clean tissue. If any changes to the normal skin appearance, such as itching, redness, swelling on and around the test area occur at any time during testing or hair coloring, rinse off immediately, stop using the product and consult a doctor. This test represents an important precaution measure which has proved to be reliable when carried out under the conditions outlined. However, be aware that even if an Allergy Alert Test has been carried out, an allergic reaction may still be experienced when coloring the hair. The allergy alert test does not provide a guarantee that allergic reactions will not occur in the future. Seek medical advice if any doubt. If during product use or in the following days, the client experiences scalp/ skin stinging, burning, blistering, weeping, itching, rash or dizziness, faintness, shortness of breath or swelling to eyes/face, rinse immediately and discontinue use. Seek medical advice and contact the manufacturer. Keep the instructions in case the client experiences a reaction. Do not use when the hair has previously been colored with henna or metal dyes. Remove all metal objects from hair before application and keep them away during product use. Do not use metal bowl/stirrer for mixing. Avoid inhaling product and hold away from face when opening. Mix in a well-ventilated room. If you experience inhalation difficulties, leave the room. Use mixture immediately and do not exceed the development time stated. Avoid unnecessary skin contact, inhaling or ingesting product. Rinse if unnecessary skin contact occurs. Keep developer away from heat and light. Do not leave the mixture in a closed bottle as it may expand/burst. Rinse hair well after application. If product reacts during service (e.g. foaming, steaming or it gets hot) do not proceed further, rinse hair immediately.
