Final answer:
A Square haircut typically begins at the back of the head, specifically near the top, to create a reference point and build a balanced shape.
Step-by-step explanation:
You begin a Square haircut at what part of the head? The correct answer is b) Back, and to be more precise, near the top of the back of the head. In the execution of a square haircut, it's essential to establish a strong guideline or reference point from which the rest of the haircut can follow.
Most professional stylists start at the back because it allows for a clear connection point for the square shape to be built upon as they work through the sides and finish at the front. This method ensures that the haircut maintains a consistent length and balanced proportions throughout. By starting near the top of the back, the hairdresser can control the layering and graduation better, which are key elements in achieving a precise square or boxy silhouette.
