Here's why:
* Grease and oil: Grease and oil on your hair can interfere with the dye's ability to penetrate the hair shaft properly. This can lead to uneven color, dull results, and potentially even damage.
* Product buildup: Hair products like conditioners, styling gels, and serums can also create a barrier, preventing the dye from reaching the hair properly.
* Clean hair is best: A clean slate allows the dye to adhere to your hair strands more effectively, resulting in a more vibrant and even color.
Here's what you should do before dyeing your hair:
1. Wash your hair with a clarifying shampoo: This will remove any buildup from products and natural oils.
2. Condition as usual: Condition your hair to make it smooth and manageable.
3. Let your hair air dry completely: This will prevent water from diluting the dye and ensure it reaches the hair shaft correctly.
By following these steps, you'll achieve the best possible results from your hair dye and avoid potential problems.
