Hey there! Here's how to use our Rubine hair colour. First, you need to do a patch test on your skin. This is really important to make sure you're not allergic to the product. Next, wash your hair and dry it with a towel. Once your hair is dry, take a tint brush or comb and spread the dye evenly through your hair. Now, be patient and let the dye work its magic for around 20 to 45 minutes. After that time, rinse your hair with water until the water runs clear. Remember, for a really bright and vivid color, it's best to use the dye on bleached or pre - lightened hair. But if you have untreated hair, you'll still get a nice, subtle tint. And since it's a vegan and cruelty - free product, you can feel good about using it. There's no need to worry about any harsh chemicals harming your hair because of the conditioning formula. It'll keep your hair soft and silky. Enjoy your new look!
