The primary function of a barber's straight razor is for close shaves and detailing haircuts. This tool is specifically designed to achieve the closest possible shave by closely following the contours of the skin, which helps in removing hair very close to the surface. This quality makes it highly effective for creating defined lines and sharp edges within hairstyles. In barbering, straight razors are often used for finishing touches that require precision and a clean look, which can enhance the overall appearance of a haircut.

The other options do not capture the primary purpose of the straight razor. While cutting hair into different lengths and creating layers can be accomplished with various tools, they are generally better suited for techniques using scissors, clippers, or other types of razors. The introduction of texture in hair is often done with specialized shears or texturizing tools rather than a straight razor. Thus, option C encapsulates the primary aspect of the razor's usage in providing both closeness in shaving and precision in detailing haircuts.
