An ancillary effect of the policy is that it reinforces the elimination of accommodations for transgender soldiers, requiring them to dress and meet the standards of their birth gender.

The Army announced updated appearance, grooming, and uniform standards following a force-wide review, emphasizing professionalism and discipline as reflections of Army values. Key changes include clarified rules on hairstyles, cosmetics, fingernails, jewelry, uniforms, insignia, and body composition assessments. Developed with input from leaders across the Army, the policy is intended to realign standards with warfighting priorities and eliminate ambiguity.

The Army also reinforced its facial hair policy in July 2025 through Army Directive 2025-13, requiring soldiers to remain clean-shaven in uniform or while on duty in civilian clothes, with only temporary medical exemptions and permanent religious accommodations.

The Council on American-Islamic Relations (CAIR) called on the Pentagon to protect the religious rights of military personnel after Defense Secretary Pete Hegseth announced a new "no beards" policy. Hegseth told military leaders, "no more beards… we're going to cut our hair, shave our beards and adhere to standards." CAIR urged the Department of Defense to clarify that religious accommodations will remain in place for Sikhs, Muslims, Jews, and others.

Historically, the rule in the US Army for about 100 years has been that the Army allows religious freedom and will accommodate as much as it can. However, the priority is always the mission, followed by the men, or in Army terms, "mission, men." While attempts would be made to accommodate religious practices, if a practice prevents a soldier from carrying out duties, then that individual cannot serve.

For example, Jewish soldiers were allowed to wear a yarmulke under their helmet because it did not interfere with equipment. But a beard, even for religious reasons, was not permitted because a protective mask would no longer seal. Similarly, a Sikh turban could not be worn with a combat uniform because it interfered with the helmet and other equipment

From 1948 to 1984, Sikh men were permitted to serve in the US military while wearing beards and turbans. That changed in 1984, when Gen. John A. Wickham Jr., then Chief of Staff of the Army, eliminated the exception for Sikhs and others who wore "conspicuous" items of faith, citing health and safety concerns. The official reasoning was that turbans and uncut hair interfered with helmets and equipment, while beards prevented protective masks from sealing properly.
