Here's why:
* Different Chemical Compositions: Cream developer is designed for use with traditional hair color, which uses ammonia and peroxide to lift and deposit color. Gel color, on the other hand, utilizes a different chemical composition and relies on a UV lamp to cure the color.
* Incompatibility: Mixing cream developer with gel color will likely result in an unpredictable reaction. It could lead to uneven color application, an undesirable color result, or even damage to your hair.
* Gel Color Activator: Gel color requires a specific activator, often a gel or liquid formula, that is designed to work with the gel color's chemical composition. This activator helps to cure the color under the UV lamp.
To use gel color correctly, you need to:
* Purchase a gel color kit: These kits usually include the gel color, activator, and instructions.
* Follow the instructions carefully: Ensure that you understand the recommended application technique, curing time, and any other specific instructions.
Remember: Using the wrong products can lead to poor results and potentially damage your hair. If you have any questions about using gel color, it's best to consult with a professional hair stylist.
