Final answer:
In a triangular one length above the shoulders haircut, forward over-direction is used. This creates a shorter front and a longer back, giving the haircut the desired triangular shape with a professional finish.
Step-by-step explanation:
Triangular One Length Haircut Over-Direction
When cutting a triangular one length above the shoulders haircut, the type of over-direction commonly used is forward over-direction. This technique involves combing and pulling the hair towards the front of the head before cutting. This method of over-direction helps create a shorter front and a longer back, resulting in the desired triangular shape. The key is to maintain consistent tension and over-direction to ensure an even and balanced cut around the head.
It's important for stylists to pay careful attention to the head shape, the natural fall of the hair, and the angle at which the hair is held and cut. These factors all contribute significantly to achieving the perfect triangular one length cut, leaving a professional and stylish outcome.
