What the Army haircut regulation actually requires

The Army has specific rules about how short your hair must be, written in Army Regulation 670-1. The regulation does not mandate one single haircut style — it sets length limits and appearance standards that your hair must meet. For men, the most common standard is that hair on top of the head cannot be longer than 1 inch when measured from the scalp, and the sides and back must be tapered and blend smoothly. For women, hair must be neat and professional; it can be longer, but it cannot fall below the collar when worn down, and it must be secured if it reaches past the collar.

The reason for these rules is military readiness and uniformity. The Army views grooming standards as part of discipline and unit cohesion. A soldier who meets grooming standards is seen as someone who follows orders and maintains military bearing. The regulation applies to all active duty soldiers, National Guard members, and Army Reserve soldiers while they are in uniform or on duty.

The specific measurements and rules can shift slightly depending on your hair type and texture. Soldiers with curly or textured hair may have different length allowances because the hair naturally takes up more space. Your unit's first sergeant or barber can tell you exactly what passes inspection in your command, since some units enforce the standard more strictly than others.

Key Takeaways

  • Army Regulation 670-1 sets hair length limits: typically 1 inch on top for men, and for women, hair must not fall below the collar when worn down.
  • The regulation allows for variation based on hair texture, so soldiers with curly or textured hair may have slightly different length allowances.
  • Hair must look neat and blend smoothly; the standard is about appearance and military bearing, not just length.
  • Your unit's first sergeant or barber is the best source for what will pass inspection in your specific command.

How the measurement works in practice

When a barber or supervisor checks your hair against regulation, they are measuring from the scalp outward. For the top of the head, they measure the longest hair and check that it does not exceed 1 inch. For the sides and back, they look at how the hair tapers — it should gradually get shorter as it moves down the neck and sides, not cut in a sharp line or left shaggy.

The taper is as important as the length. A regulation haircut typically means the sides are cut shorter than the top, creating a gradual blend. This is why a standard military barber cut looks the way it does: short on the sides, slightly longer on top, and everything blending together smoothly. If your hair is cut to 1 inch on top but the sides are not tapered, it will likely not pass inspection.

Women's hair standards focus more on neatness and how it sits when worn down. If your hair is longer than collar length, you must wear it up in a bun or similar style that keeps it off your collar and looks professional. The bun must be centered on the back of the head and secured so it does not come loose during the day.

What happens if your hair does not meet the standard

If your hair fails inspection, you will be given a direct order to get it cut to regulation within a set timeframe — usually a few days. This is not optional. Failure to comply after being ordered is a violation of military law and can result in disciplinary action, which may include loss of pay, extra duty, or more serious consequences depending on how many times you have been told.

The first time you fail inspection, your chain of command will usually give you a warning and a important date. If you show up for the next inspection with hair that still does not meet the standard, the consequences become more serious. Repeated violations can lead to a formal counseling statement in your file, which affects your performance record and promotion potential.

In practice, most soldiers get their hair cut regularly — often every two weeks — to stay well ahead of the standard. This is cheaper and easier than dealing with an inspection failure. Many military installations have barber shops on base that understand the regulation perfectly and can cut your hair to standard in one visit.

Exceptions and special circumstances

The Army does allow exceptions for medical reasons. If you have a scalp condition, dermatological issue, or other medical problem that makes it painful or unsafe to cut your hair to the standard length, you can request a medical waiver from your unit's medical officer. You will need documentation from a doctor explaining the condition and why the standard haircut would be harmful. With a waiver, you are temporarily excused from the standard, but you must still keep your hair as neat and professional as possible under your medical restriction.

Religious accommodations are also possible in some cases. If your faith requires you to wear your hair in a certain way — for example, Sikh soldiers who wear uncut hair and turbans — you can request a religious accommodation. The Army has procedures for reviewing these requests, though approval is not automatic and depends on whether the accommodation can be granted without affecting military readiness or safety.

Soldiers on medical leave or temporary duty assignments may have different enforcement, but the standard itself does not change. If you are unsure whether your situation qualifies for an exception, talk to your first sergeant or your unit's chaplain.

How the standard differs by branch and rank

The Army standard applies to all ranks equally — a private and a colonel must both meet the same hair length and appearance requirements. However, other branches of the military have slightly different rules. The Marine Corps typically enforces a shorter standard than the Army. The Navy and Air Force have their own regulations that may allow slightly longer hair. If you are moving between branches or considering enlisting in a different service, ask about that branch's specific grooming standards.

Within the Army, some special units — like certain airborne or special operations units — may have stricter or more strictly enforced standards, but the regulation itself does not change based on your unit type or your rank. What does change is how closely your unit inspects and how quickly they act if someone is out of standard.

Where to find the full regulation and get clarification

The complete grooming standards are in Army Regulation 670-1, titled "Wear and Appearance of Army Uniforms and Insignia." You can read the full text on the Army Publishing Directorate website, though the language is formal and technical. The regulation is long and covers uniforms, insignia, and jewelry as well as hair, so finding the hair section takes some reading.

For a clearer explanation, your unit's first sergeant is your best resource. They enforce the standard every day and can show you exactly what will pass in your unit. Your barber — especially if they work on a military installation — also knows the standard well and can cut your hair to meet it. If you are not sure whether your hair currently meets the standard, ask either of them to check before you show up for an official inspection.

Frequently Asked Questions

Can I wear my hair in braids or locs if they are short enough?

Braids and locs are allowed under Army Regulation 670-1 as long as they meet the length and appearance standards. The hair itself must not exceed 1 inch when measured from the scalp, and the overall style must look neat and professional. Braids must be uniform in size and neatly arranged. Check with your first sergeant about your specific unit's interpretation, since enforcement can vary.

What if I have a very curly or textured hair type?

The regulation accounts for hair texture. Soldiers with curly, coily, or textured hair may be measured differently because the hair naturally compresses and takes up less length than straight hair of the same measurement. Your barber or first sergeant can measure your hair correctly for your hair type. The key is that the hair must look neat and professional, not just meet a specific number.

Do I have to get a haircut before basic training?

You do not have to, but it is a good idea. When you arrive at basic training, your hair will be cut to regulation as part of the in-processing. If you show up with very long hair, the barber will cut more off. Getting a regulation cut before you arrive means you will not lose as much hair and you will already know what the standard looks like.

What if my barber cuts my hair too short or uneven?

If your hair is cut unevenly or too short, tell your barber when ready so they can fix it. Most barbers will correct a bad cut at no extra charge. If the barber is on a military installation, they understand the regulation and should fix it right away. If you are using a civilian barber, bring a photo of a regulation cut or describe the standard clearly so they understand what you need.

Can women wear their hair down if it is exactly at collar length?

No. The regulation states that hair must not fall below the collar when worn down. If your hair reaches the collar, it must be worn up in a secured style. "At the collar" is considered the same as "below the collar" for regulation purposes, so if there is any doubt, wear it up.
