Seems those that bring you hair color in a box have gotten the message. You'll notice more fruity scents rather than something that smells like a toxic waste dump when using them. Apparently all part of an effort to make the time spent coloring your hair seem more like putting on make_up rather than doing something that requires you don a hazmat suit.
But any such stigma associated with coloring our mane is long gone. Anymore it's so common no one gives it a second thought. In fact some of us would be hard pressed to recognize our own natural hair color it's been so long since we have seen it. Because as they say color is a girl's best friend.
