Final answer:
The braid that is created by adding hair from the sides into the strands as they are crossed over each other is known as a Dutch braid, which is characterized by its raised and plaited appearance.
Step-by-step explanation:
The braid described in the question is called a Dutch braid. This is a style of braid where hair is picked up from the sides and added to the strands as they cross over each other. Unlike the three-strand braid, which is more straightforward, or the fishtail braid that involves weaving smaller sections of hair together, the Dutch braid has a distinctive look because it appears as though it's sitting on top of the hair. The cornrow is a type of braid that is close to the scalp, typically in straight rows. The Dutch braid can be recognized by its raised, plaited appearance, making it a popular choice for both casual and formal hairstyles.
