So I’m a noob at dying hair and using bleach. I’m really not sure how to do my hair, it’s dark brown fading to chestnut auburn brown with a pluck of hair that’s now faded red. Can I dye it dark brown first and then bleach the stripes or do I section my hair and dye both the colors at the same time? Can someone make a step by step and what I should use 🙏
