To use this Love Colours Green Venus Colour Conditioner, first put on protective gloves to prevent staining. Then, apply a good amount to clean, damp hair. Leave it on for 5 - 10 minutes and then rinse thoroughly. Remember, this product is for external use only. It has ingredients that might cause skin irritation, so do a patch test before using. Apply a small amount to clean, dry skin like the back of your neck or elbow. Let it dry and leave it alone for 24 hours. Check the area after 24 and 48 hours. If there's irritation or an abnormal reaction, stop using it and see a doctor. Avoid getting it in your eyes and don't use it on your eyelashes or eyebrows as it could cause blindness. This product is only for the hair on your head. Also, it's a good idea to do a patch test for any new product before regular use. If you notice redness or itching, stop using it right away.
