Important points about Radico Organic Hair Dye: After adding water to the powder and preparing the paste, apply it immediately to the hair. Do not leave the paste to dry, otherwise you will not get good results. If your hair has been blonded or chemically treated, It may not be possible to get the colour result you want immediately after the first treatment and you may need to colour again. To achieve a darker colour for each shade, leave the paste on for longer and heat with a hairdryer. If this is the first time the colour is applied, it may not give optimal results; especially if the hair is severely damaged, either from previous chemical treatments or from poor hair condition. Therefore, a second or third application may be required. At least 24 hours should elapse between the first and second or second and third application. No shampoo or conditioner is required after rinsing the hair, but can be used if desired. Once the process is complete, it is important to note that hair can continue to darken for up to five days. For best results, wash your hair every 2-3 days if possible, as the organic hair dye continues to work on the hair even after rinsing with water. Organic hair dye is safe to use on permanently curled hair. Remember that organic hair dye is 100% natural and made only from organic plants. The result may be milder compared to dyes based on chemical ingredients. Please don't think of it as a defect but as the beauty of Mother Nature. Please be patient and enjoy the natural results of organic hair colouring. Depending on the health of your hair, results may vary from person to person. If a person is sensitive or allergic to a particular plant, they may experience some sensitivity or allergies even though this is a 100% natural product, made only from organic plants. There are very few people like this. Therefore, as a precautionary measure, we recommend a sensitivity test before use. About the colours: Being 100% natural, the colour can vary from person to person. In order to accurately determine the colour after topcoat application, we recommend a test on a small section of hair before colouring the entire head. Problems: In very rare cases, and for a variety of reasons, hair may be left with a purple tint after a mild application of black dye, And after a brown dye application, it can leave an orange tinge. In this case, the following measures can be taken: - In the case of a purple tint, a natural henna paste can be applied to the hair and the hair will turn black. - In case of an orange shade, apply a paste of indigo powder and the orange shade will disappear. Safety Do not use if allergic to any of the constituent plants. Test a small amount on your skin before use. Do not use on eyebrows or lashes. Avoid contact with eye area. Do not dye hair if you have a skin rash or a delicate, irritated and/or damaged scalp. Keep out of the reach of children.
