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.
Then how committed are you to your color choice? In other words are you ready for a permanent change or are you still dabbling so that semi_permanent color would be a safer way to go?
