Final answer:
The technique described for alternately crossing side strands over the middle one without adding extra hair is characteristic of a Three-strand braid.
Step-by-step explanation:
The technique described, where the first side goes over the middle strand and then the other side section goes over the middle strand, refers to a Three-strand braid. A Dutch braid is created in a similar way but involves tucking the strands under rather than over. A French braid also begins with three strands but includes the addition of hair from the sides as you progress down the braid, which is not described in your initial technique. Cornrows are much smaller and often tighter to the scalp braids that can also incorporate a three-strand method, but they are done in rows across the scalp. In summary, a basic three-strand braid is conducted by alternately crossing the side strands over the middle one without adding additional hair from the sides.
