* Conditioner creates a barrier: Conditioner coats the hair shaft, creating a barrier that prevents the dye from penetrating the hair cuticle.
* Dye needs access: For hair dye to work, it needs to reach the inner layers of the hair shaft to deposit pigment. Conditioner blocks this access.
* Uneven results: If you try to dye hair with conditioner in it, the dye may take unevenly, resulting in patchy color or streaks.
To ensure proper hair dye application:
1. Wash your hair with a clarifying shampoo: This removes any product buildup, including conditioner, from your hair.
2. Thoroughly towel-dry your hair: Don't apply dye to soaking wet hair. Damp hair is ideal.
3. Avoid applying conditioner after dyeing: Wait at least 24 hours before using conditioner.
Exceptions:
* Some temporary dyes: Some temporary hair dyes are designed to be applied to conditioned hair. However, these dyes don't permanently change your hair color.
* Toning: In some cases, toners can be applied to conditioned hair to refresh or subtly change the color.
Always follow the instructions on your hair dye product for the best results.
