Which of the following is used for styling hair in a salon?

The correct choice is the first option, which highlights combs and scissors as essential tools used for styling hair in a salon. Combs are integral for sectioning, detangling, and smoothing hair, while scissors are fundamental for cutting and shaping hair to achieve the desired style. These tools are versatile and allow hairstylists to create a wide range of looks, from simple trims to intricate hairstyles.

In contrast, the other options are more specialized or limited in scope. Razors are indeed used in hairstyling, but they may not encompass all aspects of the styling process. Electric shavers are primarily designed for shaving and might not be suitable for styling hair in the traditional sense. Therefore, the combination of combs and scissors is the most comprehensive and commonly used method for hair styling, making it the best answer for this question.
