Final answer:
Using "Double-Notched" thinning shears will result in a textured and feathered look by blending and softening lines without notably reducing hair volume. Hence option B is correct.
Step-by-step explanation:
When cutting hair using "Double-Notched" thinning shears, the result will be b) a Textured and feathered look. Thinning shears have teeth or notches on one side while the other side is a smooth blade. The double-notched variant has two sets of teeth, which remove less hair with each cut compared to single-notched thinning shears. This creates a more subtle thinning effect, perfect for adding texture and softening lines without causing a drastic reduction in hair volume. By blending and removing bulk where necessary, they contribute to a style that has more movement and a feathered appearance, as opposed to creating blunt, straight edges or uniform layers. These shears are often used to create a seamless transition between hair lengths in a haircut.
