There is no part of the body that announces itself more quickly than the hair. The face can be obscured. The body can be clothed. The hair is, in almost every human culture, the first thing that is read - in photographs, in hallways, in the first second of meeting someone new. The hair is also, perhaps for this reason, the part of the body on which we are most likely to spend the longest hours, in front of the smallest mirror, with the most particular attention. We are, all of us, to one degree or another, amateur hairdressers.

And yet we rarely talk about hair in the language of identity. We talk about it in the language of products - what to use, how to style, which trends to follow. We talk about it in the language of problems - dryness, breakage, frizz, oiliness, the long list of complaints that the industry exists, in part, to address. We do not, often enough, talk about it in the language of self. We do not say: this is the part of me that I have decided to make visible. This is the part of me I have spent the most hours with. This is the part of me I have chosen, again and again, every morning, to be a certain way.

The portrait we did not sit for

It is worth thinking about why hair carries this particular weight. The psychologist might say it has to do with visibility, with the way the hair is read before the rest of the body is parsed. The anthropologist might say it has to do with culture - with the long history of hair as marker of tribe, of age, of marital status, of profession. The poet might say something simpler, which is that hair is the only part of the body that grows after death. It carries, in its slow accumulation, the mark of time.

What is true, regardless of the explanation, is that we present ourselves to the world through our hair in a way that is harder to do through any other part of the body. A haircut is a sentence. A color is a paragraph. A style that is, on the face of it, very similar to last year's style is, in fact, an entirely different sentence. The hair is, in this sense, the only portrait we make of ourselves that other people get to see. We do not choose the shape of our faces. We do not choose the color of our eyes. We choose, almost entirely, the cut and color and texture of our hair. This is a fact worth sitting with.

The ritual of the morning

Most of us have a hair ritual, even if we do not call it that. The way the brush goes through, slowly, before the day begins. The way the product is warmed between the palms before being applied. The way the part is checked, and re-checked, against the mirror, until it falls just so. These are not tasks. They are closer to the way one might arrange a small altar - carefully, repeatedly, with the sense that the arrangement matters even when no one else will see it.

The hair ritual is, in many ways, the first beauty ritual we learn. It is the one that children observe, in their parents and older siblings, before they have any language for what is being done. It is the one that is taught to us, often, by the hands of others - the mother braiding, the grandmother combing, the auntie trimming. We absorb it before we have the words for it. By the time we are old enough to do it ourselves, the ritual is already in the hands.

The salon as confessional

There is a particular intimacy to the chair at the hairdresser. The mirror is angled so that you cannot see yourself without seeing the person behind you. The hands are at your head, working. The conversation, if there is conversation, is uncharacteristically close. There is, in this arrangement, something almost sacramental. The hairdresser is, for an hour or two, the only other person allowed to touch the part of you that you have decided to make public. The conversation that happens in that chair - the confidences, the small reports, the quietly important stories - is not incidental to the haircut. It is part of the haircut.

What we cut, what we keep

Haircuts are among the most legible life events. The bob that arrived in the year of the divorce. The long hair that lasted through the marriage and the children and the long quiet of the decade after. The shaved head that announced, at thirty-eight, a self that had not been there before. We cut our hair at the moments when we most need to mark something - a beginning, an ending, a turn. The cut is faster than a sentence but slower than a decision. It is, for the body, what the first paragraph is for the book.

There is also the question of what we keep. The hair we have decided not to cut, the color we have decided not to dye, the texture we have decided to wear as it is rather than as the industry would prefer it. To keep one's hair, in some basic sense, untouched is also a decision. It is the decision to wear what one was given. It is, in a world that constantly suggests we should be otherwise, its own quiet resistance.

The freedom of the bad hair day

There is, oddly, a freedom in the bad hair day. The face that has stopped trying to perform. The hair that has refused, for the morning, to be anything in particular. We live in a culture that has elevated the polished look to such a height that the unpolished look has become, by contrast, almost radical. To wear one's hair badly is to opt out of the constant small labor of presentation. It is to say: today, this is what I have. It is not what I am offering the world. It is what I have.

Hair, and the rest of the body

There is something almost absurd about the amount of attention we pay, as a culture, to the hair on our heads, and the almost no attention we pay to the hair on the rest of our bodies. The face is smoothed. The legs are cleared. The eyebrows are shaped. The hair on the head, alone, is allowed to grow and to be styled and to take up space. This asymmetry is not natural. It is cultural. It is the result of a long history of choices about which body hair is acceptable and which is not, and those choices change, decade by decade, in ways that are easy to forget were not always true.

What this means is that the way we wear our hair - the cut, the color, the texture - is not just an aesthetic choice. It is a participation in a long conversation about which bodies are allowed to be visible, and how. To grow one's hair long is, in one context, a feminine statement. In another, it is a political one. To shave one's head is, in one context, a practical decision. In another, it is a refusal. The same hair, on different heads, in different decades, means different things. We do not choose our hair in a vacuum. We choose it in the middle of a long argument.

Where this leaves us

The next time you find yourself in front of the mirror with a comb in your hand, consider what is happening. You are not, strictly speaking, fixing your hair. You are deciding, in a small way, what kind of a day you are going to have. You are deciding, in a small way, what kind of a self you are going to present to the world. You are also, in a small way, continuing a conversation that began long before you were born - the conversation about which bodies are visible, and how, and to whom, and at what cost.

The hair on your head is not the most important part of you. It is, however, the most legible. It is the part of you that the world sees first. It is the part of you that the world makes assumptions about. It is the part of you that you, alone among the parts of your body, get to decide, again and again, every morning, whether to change or to keep. That is not a small thing. That is, in fact, one of the larger freedoms we have.

To use it well is to remember that it is a freedom. To use it lightly is to remember that the hair will grow back. To use it deliberately is to remember that the self you present, today, is one of many possible selves, and that choosing among them is not vanity. It is authorship.
