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.
In any case, it's certainly true that coloring your locks can change the way you look. It can revitalize things taking them from boring to fresh and new. Which is why so many of us have wholeheartedly embraced coloring our locks. You just want to make sure the change is for the better.
