Did you know that the color you're aiming for can also affect the processing time? For example, if you're going for a blonde bombshell look, you might need to let the dye sit for a bit longer, around 45-60 minutes. But, if you're opting for a rich, dark color, you might get away with a shorter processing time, around 20-30 minutes.

And, fun fact: some hair dyes contain ammonia, which can be pretty harsh on your locks. But, don't worry, there are ammonia-free options available, which might be a better choice for those with sensitive scalps or damaged hair.
