What is the process of cutting hair shorter called?

The process of cutting hair shorter is referred to as haircutting or trimming. This term encompasses the various techniques used to modify the length of the hair, whether it involves creating a significant change in length or simply maintaining a style by removing split ends and refreshing the overall look. Haircutting is a fundamental skill for barbers and hairstylists, as it allows them to enhance the client's appearance according to their preferences.

In contrast, thinning is typically used to reduce bulk in thick hair rather than to shorten it, focusing on texturizing. Styling refers to arranging the hair in a particular way, often using products and tools to create a desired look, rather than cutting the hair itself. Shaping can imply both cutting and styling, but it is often more about creating a specific silhouette rather than just shortening the hair. Thus, haircutting or trimming is the most accurate term for the action of reducing hair length.
