Step-by-step explanation:
The method that involves sewing weft or natural hair onto a cornrow braid and wrapping it to create African locks or dreadlocks is called Twisting.
Twisting is a popular method used to create dreadlocks. It involves dividing the hair into sections and twisting each section with a comb or by hand. This method is effective for all hair types, including weft or natural hair.
For example, if you have weft or natural hair and want to create African locks or dreadlocks, you can divide your hair into small sections, apply a styling product or gel to make the hair more manageable, and then twist each section tightly. As you twist, you can wrap the hair around itself to create the desired lock or dreadlock shape.
