I cover my hair. Every day. Not when I am by myself, necessarily, but in the presence of others and certainly in public.
This is an actual law in Judaism, like keeping kosher or eating matzah on Passover. I grew up unaware of it. There were always certain things in Judaism that I was pretty sure Orthodox people did, but I didn't do. Like keeping Shabbos, for example. Or the observance of many other holidays, or that the women always seemed to be wearing skirts, or that the men attended frequent prayer services.
Then, from about age 18, I started to realize that those Orthodox Jews were actually keeping Judaism, not 'Orthodoxy', in the form that it was originally established and had been observed for thousands of years. And that the laws they were living by were amply supported by generations of scholarship and extensive documentation of sources.
Then, at age 20, I said to myself, "Enough is enough. I can't live in contradiction anymore, I can't ignore that I was born Jewish, I can't find sufficient answers in Reform or Conservative Judaism like I can in Orthodoxy, and if this religion is true, I have to change for it, even though I didn't grow up with knowledge of these things, and even though I am more comfortable living the way I do at present, than changing."
So I began to gradually live, eat, sleep, pray, dress, and behave like a religiously observant Jewish person. I educated myself on what I would need to fill this role, and to one day raise my children this way, and to prepare to have a marriage that reflected the beautiful moral values I had discovered in the Torah.
One law that I became aware of, but didn't observe because it didn't apply to me as a single person, was the law of hair covering. Then, last June, I got married.
My hair is now covered. It's a statement of modesty that was actually observed in more cultures up until pretty recently in human history when it went out of fashion. The difference with the Jewish religion is that because the laws are divine in origin, they didn't change just because women don't cover their hair in other cultures (especially Western culture). Jewish women were covering their hair 3,300 years ago, preceding the cultures that have risen and fallen since, in which women covered their hair. And trust me, they will continue to cover their hair, regardless of the trend to do so or not to do so. That's what it means to keep a law that is divine in origin. The source is way,way above public opinion or popular science, and it's older and much more substantiated.
It's interesting, because before I followed Torah, my hair WAS subject to Allure Magazine's advice that 'blunt bangs are in' (regardless of the face shape of the reader, of course), or that I needed to have the perfect layers, or that auburn lowlights were a must for the fall season. If I think back on the significance of my hair at the time, it was an object to me. I used it as a tool to try and define myself, albeit in an unsatisfying manner (true self-definition can never come from something as fleeting as hair).
Now my hair is subject to a few considerations-
What will keep it at its healthiest?
What style does my husband like the best?
When its covered, how do I want to cover it? Which choice of covering best reflects my values?
These questions are so much more empowered than 'how can I please everyone else in society?' which is basically the question that magazines like Allure are answering with every article and headline.
When I cover it, I am reconnecting to G-d, and to the Torah which I believe in and strive to fulfill. In high school and college, I used to search fervently through works of poetry and philosophy to find some meaningful statement about life that I could hold on to and follow. I was baffled by the possibility that there was nothing out there. School, traffic, work, retirement, dead. It just didn't make sense, but I didn't yet have a better or clearer answer for why I was on the planet.
Now I savor the moments in my day, which occur every day and will for the rest of my life, where I perform actions that reconnect me to my source, and to the source of everyone and everything. Covering my hair is one of those moments.
