delivered the opinion of the Court.

The District Court for the Eastern District of New York originally dismissed respondent’s complaint seeking declaratory and injunctive relief against a regulation promulgated by petitioner limiting the length of a policeman’s hair. On respondent’s appeal to the Court of Appeals for the Second Circuit, that judgment was reversed, and on remand the District Court took testimony and thereafter granted the relief sought by respondent. The Court of Appeals affirmed, and we granted certiorari, 421 U. S. 987 (1975), to consider the constitutional doctrine embodied in the rulings of the Court of Appeals. We reverse.

In 1971 respondent’s predecessor, individually and as president of the Suffolk County Patrolmen’s Benevolent Association, brought this action under the Civil Rights Act of 1871, 42 U. S. C. § 1983, against petitioner’s predecessor, the Commissioner of the Suffolk County Police Department. The Commissioner had promulgated Order No. 71-1, which established hair-grooming standards applicable to male members of the police force.1 The *240regulation was directed at the style and length of hair, sideburns, and mustaches; beards and goatees were prohibited, except for medical reasons; and wigs conforming to the regulation could be worn for cosmetic reasons. The regulation was attacked as violative of respondent patrolman's right of free expression under the First Amendment and his guarantees of due process and equal *241protection under the Fourteenth Amendment, in that it was “not based upon the generally_accepted standard of grooming in the community” and. .placed “an undue restriction” upon his activities therein. '

The Court of Appeals held that cases characterizing the uniformed civilian services as “para-military,” and sustaining hair regulations on that basis, were not soundly grounded historically.2 It said that the fact that a police force is organized “with a centralized administration and a disciplined rank and file for efficient conduct of its affairs" did not foreclose respondent’s claim, but instead bore only upon “the existence of a legitimate state interest to be reasonably advanced by the regulation.” Dwen v. Barry, 483 F. 2d 1126, 1128-1129 (1973). The Court of Appeals went on to decide that “choice of personal appearance is an ingredient of an individual’s personal liberty” 3 and is protected by the Fourteenth Amendment. It further held that the police department had “failed to make the slightest showing of the relationship between its regulation and the legitimate interest it sought to promote.” Id., at 1130-1131. On the basis of this reasoning it concluded that neither dismissal nor summary judgment in the District Court was appropriate, since the department “has the burden of establishing *242a genuine public need for the regulation.” Id., at 1131.

Thereafter the District Court, under the compulsion of the remand from the Court of Appeals, took testimony on the question of whether or not there was a “genuine public need.” The sole witness was the Deputy Commissioner of the Suffolk County Police Department, petitioner’s subordinate, who testified as to the police department’s concern for the safety of the patrolmen, and the need for some standards of uniformity in appearance.4 The District Court held that “[n]o proof” was offered to support any claim of the need for the protection of the police officer, and that while “proper grooming” is an ingredient of a good police department’s esprit de *243corps, petitioner's standards did not establish a public need because they ultimately reduced to “[ujniformity for uniformity’s sake.” 5 The District Court granted the *244relief prayed for by respondent, and on petitioner's appeal that judgment was affirmed without opinion by the Court of Appeals. 508 F. 2d 836.

I h-I

Section 1 of the Fourteenth Amendment to the United States Constitution provides in pertinent part:

“No State shall . . . deprive any person of life, liberty, or property, without due process of law.”

This section affords not only a procedural guarantee against the deprivation of “liberty,” but likewise protects substantive aspects of liberty against unconstitutional restrictions by the State. Board of Regents v. Roth, 408 U. S. 564, 572 (1972); Griswold v. Connecticut, 381 U. S. 479, 502 (1965) (White, J., concurring).

The “liberty” interest claimed by respondent here, of course, is distinguishable from the interests protected by the Court in Roe v. Wade, 410 U. S. 113 (1973); Eisenstadt v. Baird, 405 U. S. 438 (1972); Stanley v. Illinois, 405 U. S. 645 (1972); Griswold v. Connecticut, supra; and Meyer v. Nebraska, 262 U. S. 390 (1923). Each of those cases involved a substantial claim of infringement on the individual's freedom of choice with respect to certain basic matters of procreation, marriage, and family life. But whether the citizenry at large has some sort of “liberty” interest within the Fourteenth Amendment in matters of personal appearance is a question on which this Court's cases offer little, if any, guidance. We can, nevertheless, assume an affirmative answer for purposes of deciding this case, because we find that assumption insufficient to carry the day for respondent's claim.

Respondent has sought the protectiqn.:Jíf-_the- Four*245teenth Amendment, not as a member of the citizenry at large, but on the contrary as an employee of the police department of Suffolk County, a subdivision o'f the State of New York. While the Court of Appeals made passing reference to this distinction, it was thereafter apparently ignored. We think, however, it is highly significant. In Pickering v. Board of Education, 391 U. S. 563, 568 (1968), after noting that state employment may not be conditioned on the relinquishment of First Amendment rights, the Court stated that “[a]t the same time it cannot be gainsaid that the State has interests as an employer in regulating the speech of its employees that differ significantly from those it possesses in connection with regulation of the speech of the citizenry in general.” More recently, we have sustained comprehensive and substantial restrictions upon activities of both federal and state employees lying at the core of the First Amendment. CSC v. Letter Carriers, 413 U. S. 548 (1973); Broadrick v. Oklahoma, 413 U. S. 601 (1973). If such state regulations may survive challenges based on the explicit language of the First Amendment, there is surely even more room fór restrictive regulations of state employees where the claim implicates only the more general contours of the substantive liberty interest protected by the Fourteenth Amendment.

The hair-length regulation here touches respondent as ax) employee of the county and, more particularly, as a policeman. Respondent's employer has, in accordance wijth its well-established duty to keep the peace, placed myriad demands upon the members of the police force, duties which have no counterpart with respect to the public at large. Respondent must wear a standard uniform, specific in each detail.6 When in uniform he must *246salute the flag.7 He may not take an active role in local political affairs by way of being a party delegate or contributing or soliciting political contributions.8 He may not smoke in public.9 All of these and other regulations 10 of the Suffolk County Police Department infringe on respondent's freedom of choice in personal matters, and it was apparently the view of the Court of Appeals that the burden is on the State to prove a “genuine public need” for each and every one of these regulations.

This view was based upon the Court of Appeals’ reasoning that the “unique judicial deference” accorded by the judiciary to regulation of members of the military was inapplicable because there was no historical or functional justification for the characterization of the police as “para-military.” But the conclusion that such cases are inapposite, however correct, in no way detracts from the deference due Suffolk County’s choice of an organizational structure for its police force. Here the county has chosen a mode of organization which it undoubtedly deems the most efficient in enabling its police to carry out the duties assigned to them under state and local law.11 Such a choice necessarily gives weight to the overall need for discipline, esprit de corps, and uniformity.

The county’s choice of an organizational structure, therefore, does not depend for its constitutional validity on any doctrine of historical prescription. Nor, indeed, has respondent made any such claim. His argument does *247not challenge the constitutionality of the organizational structure, but merely asserts that the present hair-length regulation infringes his asserted liberty interest under the Fourteenth Amendment. We believe, however, that the hair-length regulation cannot be viewed in isolation, but must be rather considered in the context of the county’s chosen mode of organization for its police force.

The promotion of safety of persons and property is unquestionably at the core of the State’s police power, and virtually all state and local governments employ a uniformed police force to aid in the accomplishment of that purpose. Choice of organization, dress, and equipment for law enforcement personnel is a decision entitled to the same sort of presumption of legislative validity as are state choices designed to promote other aims within the cognizance of the State’s police power. Day-Brite Lighting, Inc. v. Missouri, 342 U. S. 421, 423 (1952); Prince v. Massachusetts, 321 U. S. 158, 168-170 (1944); Olsen v. Nebraska, 313 U. S. 236, 246-247 (1941). Having recognized in other contexts the wide latitude accorded the government in the “dispatch of its own internal affairs,” Cafeteria Workers v. McElroy, 367 U. S. 886, 896 (1961), we think Suffolk County’s police regulations involved here are entitled to similar weight. Thus the question is not, as the Court of Appeals conceived it to be, whether the State can “establish” a “genuine public need” for the specific regulation. It is whether respondent can demonstrate that there is no rational connection between the regulation, based as it is on the county’s method of organizing its police force, and the promotion of safety of persons and property. United Public Workers v. Mitchell, 330 U. S. 75, 100-101 (1947); Jacobson v. Massachusetts, 197 U. S. 11, 30-31, 35-37 (1905).

We think the answer here is so clear that the District Court was quite right in the first instance to have dis*248missed respondent’s complaint. Neither this Court, the Court of Appeals, nor the District Court is in a position to weigh the policy arguments in favor of and against a rule regulating hairstyles as a part of regulations governing a uniformed civilian service. The constitutional issue to be decided by these courts is whether petitioner’s determination that such regulations should be enacted is so irrational that it may be branded “arbitrary,” and therefore a deprivation of respondent’s “liberty” interest in freedom to choose his own hairstyle. Williamson v. Lee Optical Co., 348 U. S. 483, 487-488 (1955). The overwhelming majority of state and local police of the present day are uniformed. This fact itself testifies to the recognition by those who direct those operations, and by the people of the States and localities who directly or indirectly choose such persons, that similarity in appearance of police officers is desirable. This choice may be based on a desire to make police officers readily recognizable to the members of the public, or a desire for the esprit de corps which such similarity is felt to inculcate within the police force itself. Either one is a sufficiently rational justification for regulations so as to defeat respondent’s claim based on the liberty guarantee of the Fourteenth Amendment.

The Court of Appeals relied on Garrity v. New Jersey, 385 U. S. 493 (1967), and amicus in its brief in support of respondent elaborates an argument based on the language in Garrity that “policemen, like teachers and lawyers, are not relegated to a watered-down version of constitutional rights.” Id., at 500. Garrity, of course, involved the protections afforded by the Fifth Amendment to the United States Constitution as made applicable to the States by the Fourteenth Amendment. Malloy v. Hogan, 378 U. S. 1 (1964). Certainly its language cannot be taken to suggest that the claim of a member *249of a uniformed civilian service based on the “liberty” interest protected by the Fourteenth-Amaiidment must necessarily be treated for constitutional purposes the same as a similar claim by a member of the general public.

The regulation challenged_here — did- not violate any right guaranteed respondent by the Fourteenth Amendment to the United States Constitution, and the Court of Appeals was therefore wrong in reversing the District Court’s original judgment dismissing the action. The judgment of the Court of Appeals is

Reversed.

Mr. Justice Stevens took no part in the consideration or decision of this case.

concurring.

I concur in the opinion of the Court and write to make clear that, contrary to the concern expressed in the dissent, I find no negative implication in the opinion with respect to a liberty interest within the Fourteenth Amendment as to matters of personal appearance. See Poe v. Ullman, 367 U. S. 497, 541-543 (1961) (Harlan, J., dissenting). When the State has an interest in regulating one’s personal appearance, as it certainly does in this case, there must be a weighing of the degree of infringement of the individual’s liberty interest against the need for the regulation. This process of analysis justifies the application of a reasonable regulation to a uniformed police force that would be an impermissible intrusion upon liberty in a different context.

with whom Mr. Justice Brennan joins, dissenting.

The Court today upholds the constitutionality of Suffolk County’s regulation limiting the length of a police*250man’s hair. While the Court only assumes for purposes of its opinion that “the citizenry at large has some sort of 'liberty’ interest within the Fourteenth Amendment in matters of personal appearance . . . ,” ante, at 244, I think it clear that the Fourteenth Amendment does indeed protect against comprehensive regulation of what citizens may or may not wear. And I find that the rationales offered by the Court to justify the regulation in this case are insufficient to demonstrate its constitutionality. Accordingly, I respectfully dissent.

I

As the Court recognizes, the Fourteenth Amendment’s guarantee against the deprivation of liberty “protects substantive aspects of liberty against unconstitutional restrictions by the State.” Ante, at 244. And we have observed that “[l]iberty under law extends to the full range of conduct which the individual is free to pursue.” Bolling v. Sharpe, 347 U. S. 497, 499 (1954). See also Poe v. Ullman, 367 U. S. 497, 543 (1961) (Harlan, J., dissenting).1 It seems to me manifest that that “full range of conduct” must encompass one’s interest in dressing according to his own taste. An individual’s personal appearance may reflect, sustain, and nourish his personality and may well be used as a means of expressing his *251attitude and lifestyle.2 In taking control over a citizen’s personal appearance, the government forces him to sacrifice substantial elements of his integrity and identity as well. To say that the liberty guarantee of the Fourteenth Amendment does not encompass matters of personal appearance would be fundamentally inconsistent with the values of privacy, self-identity, autonomy, and personal integrity that I have always assumed the Constitution was designed to protect. See Roe v. Wade, 410 U. S. 113 (1973); Stanley v. Georgia, 394 U. S. 557, 564 (1969); Griswold v. Connecticut, 381 U. S. 479, 485 (1965); Olmstead v. United States, 277 U. S. 438, 478 (1928) (Brandeis, J., dissenting).

If little can be found in past cases of this Court or indeed in the Nation’s history on the specific issue of a citizen’s right to choose his own personal appearance, it is only because the right has been so clear as to be beyond question. When the right has been mentioned, its existence has simply been taken for granted. For instance, the assumption that the right exists is reflected in the 1789 congressional debates over which guarantees should be explicitly articulated in the Bill of Rights. I. Brant, The Bill of Rights 53-67 (1965). There was considerable debate over whether the right of assembly should be expressly mentioned. Congressman Benson of New York argued that its inclusion was necessary to assure that the right would not be infringed by the government. In response, Congressman Sedg-wick of Massachusetts indicated:

“If the committee were governed by that general *252principle . . . they might have declared that a man should have a right to wear his hat if he pleased . . . but [I] would ask the gentleman whether he thought it necessary to enter these trifles in a declaration of rights, in a Government where none of them were intended to he infringed.” Id., at 54-55 (emphasis added).

Thus, while they did not include it in the Bill of Rights, Sedgwick and his colleagues clearly believed there to be a right in one’s personal appearance. And, while they may have regarded the right as a trifle as long as it was honored, they clearly would not have so regarded it if it were infringed.

This Court, too, has taken as an axiom that there is a right in one’s personal appearance.3 Indeed, in 1958 we used the existence of that right as support for our recognition of the right to travel:

“The right to travel is a part of the 'liberty’ of which the citizen cannot be deprived without due process of law under the Fifth Amendment. ... It may he as close to the heart of the individual as the choice *253of what he eats, or wears, or reads.” Kent v. Dulles, 357 U. S. 116, 125-126 (1958) (emphasis added).

To my mind, the right in one’s personal appearance is inextricably bound up with the historically recognized right of “every individual to the possession and control of his own person,” Union Pacific R. Co. v. Botsford, 141 U. S. 250, 251 (1891), and, perhaps even more fundamentally, with “the right to be let alone — the most comprehensive of rights and the right most valued by civilized men.” Olmstead v. United States, supra, at 478 (Brandeis, J., dissenting). In an increasingly crowded society in which it is already extremely difficult to maintain one’s identity and personal integrity, it would be distressing, to say the least, if the government could regulate our personal appearance unconfined by any constitutional strictures whatsoever.4

*254II

Acting on its assumption that the Fourteenth Amendment does encompass a right in one’s personal appearance, the Court justifies the challenged hair-length regulation on the grounds that such regulations may “be based on a desire to make police officers readily recognizable to the members of the public, or a desire for the esprit de corps which such similarity is felt to inculcate within the police force itself.” Ante, at 248. While fully accepting the aims of “identifiability” and maintenance of esprit de corps, I find no rational relationship between the challenged regulation and these goals.5

As for the first justification offered by the Court, I simply do not see how requiring policemen to maintain hair of under a certain length could rationally be argued to contribute to making them identifiable to the public as policemen. Surely, the fact that a uniformed police officer is wearing his hair below his collar will make him *255no less identifiable as a policeman. And one cannot easily imagine a plainclothes officer being readily identifiable as such simply because his hair does not extend beneath his collar.

As for the Court’s second justification, the fact that it is the president of the Patrolmen’s Benevolent Association, in his official capacity, who has challenged the regulation here would seem to indicate that the regulation would if anything, decrease rather than increase the police force’s esprit de corps.6 And even if one accepted the argument that substantial similarity in appearance would increase a force’s esprit de corps, I simply do not understand how implementation of this regulation could be expected to create any increment in similarity of appearance among members of a uniformed police force. While the regulation prohibits hair below the ears or the collar and limits the length of sideburns, it allows the maintenance of any type of hairstyle, other than a ponytail. Thus, as long as their hair does not go below their collars, two police officers, one with an “Afro” hair style and the other with a crewcut could both be in full compliance with the regulation.7

*256The Court cautions us not to view the hair-length regulation in isolation, but rather to examine it “in the context of the county's chosen mode of organization for its police force.” Ante, at 247. While the Court’s caution is well taken, one should also keep in mind, as I fear the Court does not, that what is ultimately under scrutiny is neither the overall structure of the police force nor the uniform and equipment requirements to which its members are subject, but rather the regulation which dictates acceptable hair lengths. The fact that the uniform requirement, for instance, may be rationally related to the goals of increasing police officer “identifi-ability” and the maintenance of esprit de corps does absolutely nothing to establish the legitimacy of the hair-length regulation. I see no connection between the regulation and the offered rationales 8 and would accordingly affirm the judgment of the Court of Appeals.
