What type of braiding is typically used as a base for sew-in weaves?

Cornrow braiding is the type of braiding typically used as a base for sew-in weaves due to its flat and secure nature. When cornrows are created, they lie close to the scalp, providing a stable foundation that allows the extensions or weave to be stitched securely. This method minimizes bulkiness and helps ensure the weave lays flat against the natural hair, creating a seamless look.

Additionally, cornrows can be styled in various patterns, making them versatile for different sew-in applications. Their tightness and neatness also contribute to the durability of the weave, allowing it to hold in place for extended periods without causing unnecessary strain on the natural hair.
