Cutting hair with a straight razor at a 45-degree angle is recommended because this angle allows for a smooth, controlled cut while effectively removing bulk and creating soft texture. This technique is commonly used to achieve a variety of styles, especially when the stylist is looking to add layers or provide a more textured finish. The 45-degree angle helps maintain the integrity of the hair strands during the cutting process, minimizing frizz and ensuring a clean line.

In addition, using a straight razor at this angle also helps in blending, as it allows for a more gradual transition between lengths. This is particularly important in today's hairstyling trends, where seamless layers are desired. The angle also gives the stylist better leverage when performing the cut, making it easier to maneuver the razor through the hair.

Other angles, such as 30 degrees, may not allow for sufficient cutting power or may result in uneven layers, while angles like 60 or 90 degrees could lead to a choppy appearance or difficulty in blending, which can negatively affect the overall look of the hairstyle. Therefore, the 45-degree angle is optimal for both stylistic precision and effective hair texture management.
