Final answer:
The three basic categories of female hairstyles in AR 670-1 are short, medium, and long length, each with specific requirements to maintain a professional appearance and ensure they do not interfere with uniform headgear.
Step-by-step explanation:
The question refers to AR 670-1, which is the United States Army Regulation that dictates the wear and appearance of army uniforms and grooming standards. Among these regulations, there are specific guidelines regarding the hairstyles for females in the Army. Though the provided chapters do not directly relate to AR 670-1, the three basic categories of female hairstyles discussed there are short length, medium length, and long length.
Short Length Hair
For short hair, the regulation states that it must not interfere with the proper wear of all uniform headgear. Hairstyles should not exceed certain bulk and length limits and must present a neat, professional appearance.
Medium Length Hair
Medium-length hair must be secured, if necessary, to ensure that it does not fall over the eyebrows or below the collar's lower edge while in uniform. Like short hairstyles, it should maintain a professional appearance and not impede the wear of headgear.
Long Length Hair
Long hairstyles must be fashioned so that they can be neatly and securely fastened at the back of the head, not falling below the bottom of the collar, and not impeding the proper wear of headgear.
