Before using this or any new hair product, do a patch test on a small area of your skin. Wait 24 hours. If you notice redness or itching, don't use the product. To maintain your hair color, use a color - safe shampoo and conditioner. Also, avoid excessive sun exposure as it can fade the color. This vegan hair dye is a great choice for those who care about animal - friendly products and want to add a fiery touch to their hair.
