Millions of people around the world safely use hair colours regularly. However, in rare cases, allergy from hair colour products may develop at any time and at any stage in life, like many other food items we commonly know of, that are pulses, milk, brinjal, fish, crabs, etc. Hence, a skin hypersensitivity test is strongly recommended before every application of hair colour as a precautionary measure, even for regular users to ensure safe and pleasurable hair colouring experience. All safety instructions and precautions are mentioned on the pack in detail.



The skin hypersensitivity test must be done 48 hours before application on the hair. To conduct the test, cleanse a small area of skin behind the ear or inner surface of the forearm using soap and water or alcohol. Mix a pinch of powder with 1 or 2 drops of water and apply on previously cleansed skin, allow it to dry. Keep the product on for 48 hours and observe. If there is no reaction such as reddening, burning, itching, irritation or swelling in the area that the test was conducted the product can be safely used for hair colour application.
