Hey there! Here's how to use our White Hair Toner. First, always do a patch test on your skin. This helps you avoid any allergic reactions. Next, wash your hair and dry it with a towel. Then, take a tint brush or comb and spread the toner evenly through your hair. Let it develop for about 20 to 45 minutes. After that, rinse it out until the water runs clear. Remember, for a really bright and vivid colour, it's best to use the toner on bleached or pre - lightened hair. But if you want a more subtle look, you can use it on untreated hair too. And since our products are vegan and cruelty - free, you can feel good about using them. Take care of your hair by using our toners regularly, and you'll keep your hair soft and stylish!
