Hair dyes can be a great way to change the color of your hair without going to a salon. There are many different types of at home hair dyes, so you can find one that works best for you. Some hair dyes require you to dye your entire hair at once, while others are color-safe and can be applied in small doses over time. Before using any hair dye, be sure to research the product and consult with a professional about what will work best for your hair type and color.
