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.
Hard as it is to believe there was once a time when those who colored their hair were looked down on by "respectable" women. Some would sneer, "She gets her color out of bottle, you know." Making it sound like that was a bad thing.
