The difference between duckbill clips and alligator clips largely lies in their design and use. Duckbill clips are typically long, straight, and flat, resembling a duck's bill. They are great for holding large sections of hair during styling or drying processes, especially when creating waves or volume. On the other hand, alligator clips are designed with interlocking teeth that resemble an alligator's mouth. These clips are excellent for sectioning hair during styling or cutting, providing a secure hold without slipping.
