Before we get into the nitty-gritty, let's cover the basics: hair dye works by penetrating the hair shaft and depositing color. The longer you leave it on, the more intense the color will be - but be careful not to overdo it, or you might end up with over-processed hair!
Generally, the recommended time for leaving hair dye on is between 20 to 45 minutes, depending on the type of dye and your hair type. But, let's get real - everyone's hair is different, and what works for your BFF might not work for you.
That's why it's so important to follow the instructions and do a strand test before applying the dye to your entire head. This will give you a sneak peek into how the color will turn out and help you avoid any hair disasters.
