A wave nouveau is a type of perm solution that is used to create waves or curls in the hair. It does not contain any colorants, so it will not change the color of your hair.
If you want to change the color of your hair, you will need to use a hair dye product.
Here's the difference:
* Wave nouveau: Alters the texture of the hair (makes it wavy or curly)
* Hair dye: Alters the color of the hair
It's important to remember that you should always consult with a professional hairstylist before using any hair products, especially if you are unsure about how to use them or if you have any concerns about your hair health.
