Generally speaking, permanent hair color should be left on for around 20-45 minutes, depending on the product and your hair type. If you have virgin hair (that's hair that's never been colored before), you may need to leave it on for a bit longer, while previously colored hair may require less time. It's all about finding that sweet spot, like the perfect cup of coffee - not too strong, not too weak!

But, let's get real, everyone's hair is different, and what works for your friend or sister may not work for you. That's why it's so important to follow the instructions carefully and do a strand test before applying the color to your entire head. It's like trying out a new recipe - you don't want to end up with a dish that's inedible, do you?
