Neatly trimmed and evenly graduated?

The U.S. Navy has relaxed hair length standards because of the coronavirus, according to this report in The New York Times. Such matters are normally covered by U.S. Navy Uniform Regulations art. 2201.1. Excerpt from the provision for men (the one for women is about four times as long):

Keep hair neat, clean and well groomed. Hair above the ears and around the neck shall be tapered from the lower natural hairline upwards at least 3/4 inch and outward not greater than 3/4 inch to blend with hair­style. Hair on the back of the neck must not touch the collar. Hair shall be no longer than four inches and may not touch the ears, collar, extend below eyebrows when headgear is removed, show under front edge of headgear, or interfere with properly wearing military headgear. The bulk of the hair shall not exceed approximately two inches. Bulk is defined as the distance that the mass of hair protrudes from the scalp. Hair coloring must look natural and complement the individual. Faddish styles and outrageous multicolored hair are not authorized. The unique quality and texture of curled, waved, and straight hair are recognized, and in some cases the 3/4 inch taper at the back of the neck may be difficult to attain. In those cases hair must present a graduated appearance and may combine the taper with a line at the back of the neck. One (cut, clipped or shaved) natural, narrow, fore and aft part is authorized. Varying hairstyles, including afro, are permitted if these styles meet the criteria of maximum length and bulk, tapered neck and sides, and do not interfere with properly wearing military headgear. Plaited or braided hair shall not be worn while in uniform or in a duty status. Keep sideburns neatly trimmed and tailored in the same manner as the haircut. Sideburns shall not extend below a point level with the middle of the ear, shall be of even width (not flared) and shall end with a clean shaven horizontal line. Figure 2‑2‑1 refers. "Muttonchops", "ship's captain", or similar grooming modes are not authorized.
