Where on the hair strand does a haircut take effect?

A haircut primarily takes effect at the ends of the hair strand. This is where the physical length of the hair is altered, influencing the overall shape and style of the haircut. When cutting hair, stylists remove or reshape the hair at the ends to achieve the desired look, which can vary from trimming split ends to creating an entirely new style.

While the root, mid-shaft, and entire strand are all integral parts of the hair, they do not directly reflect the immediate area affected by a haircut. The root represents the point of hair growth and is not altered with cutting, while the mid-shaft might be involved in layering or texturizing but is not the focal point of a standard haircut. The entire strand encompasses all parts of the hair but does not indicate the specific area where cutting action occurs. Thus, focusing on the ends provides the clarity needed when discussing where the impact of a haircut is most pronounced.
