Which tool is commonly used for trimming hair ends?

The use of scissors for trimming hair ends is well-established in cosmetology. Scissors provide precision and control, allowing the stylist to cut hair to a desired length while maintaining the overall shape and style of the haircut. The blades of scissors are designed to create clean, straight cuts or to layer hair by using techniques such as slide cutting or point cutting. This versatility is crucial for achieving a polished finish, especially when dealing with the delicate ends of the hair.

In contrast, other tools serve different purposes. Razors are generally used for texturizing or creating softer, blended layers but may not be ideal for simply trimming the ends. Clippers are designed for cutting hair very short or creating fades, making them less applicable for a clean end trim. A comb, while essential for sectioning and elevating the hair during cutting, does not actually perform the cutting itself. Hence, scissors emerge as the most appropriate tool for this specific task.
