So, how long should you wait? The answer varies depending on the type of dye you're using, as well as your hair type and condition. For example, if you're using a semi-permanent dye, you might only need to leave it on for 20-25 minutes, while a permanent dye might require 30-45 minutes.
It's also important to consider your hair's porosity - think of it like a sponge! If your hair is very porous, it might absorb the dye quickly, while less porous hair might take longer. It's all about finding the right balance, like Goldilocks - not too little, not too much, but just just right!
Now, you might be wondering, what happens if I leave the dye on for too long? Well, my friend, it's not the end of the world, but it can cause some unwanted effects. Over-processing can lead to dry, damaged hair, and even color overload - where the color becomes too intense and uneven. Not cute!
