What are the two determining factors if a hairstyle is acceptable?

The correct answer is based on the standards outlined in Army regulations regarding personal appearance. A hairstyle is deemed acceptable if it meets the criteria of being neat and conservative.

"Neat" implies that the hairstyle is well-groomed and tidy, without any disarray that could detract from a professional appearance. "Conservative" suggests that the hairstyle does not draw excessive attention, maintaining a level of modesty in line with military standards. These characteristics ensure that soldiers uphold the values associated with military professionalism and discipline.

The other options, while they include elements that could be part of a hairstyle’s attributes, do not encapsulate the primary focus of military grooming standards, which emphasize neatness and conservativeness above all else. Factors such as color and style, length and texture, or fashion and utility may be relevant in civilian contexts but do not align with the core evaluation criteria used in the Army.
