It should also look professional and allow you to wear uniform headgear in the proper manner, so your hair must not be too full or too high on the head. In addition, your hairstyle shouldn't need many grooming aids. If you use pins, combs, barrettes, elastic bands or similar items, they must be plain, similar in color to your hair, and modest in size. Wigs or hairpieces must also conform to these guidelines. Hair will not contain excessive amounts of grooming aids, or touch eyebrows. Hair color/ highlights/frosting (must not be faddish). No shaved heads or flat-top hairstyles for women.
