The last few years have seen a bigger_than_ever push for natural and organic beauty products. Many consumers are under the impression that components found in "organic" or "natural" hair products make them inherently safer. Unfortunately it's not that simple, according to the U.S. Food & Drug Administration. In fact, not only is organic hair dye not necessarily safer than synthetic hair dye, organic hair dye simply doesn't exist.
The last thing you want is to run out of dye halfway through the process. If your hair is shoulder length or longer, you may need two boxes to cover your whole head, depending on hair thickness. (And if you end up with a leftover box, you can always use it next time) Take the strand test : If you're trying a new shade, test it on a few trimmed hairs or hidden pieces first, and look at the result before you commit. A common horror story from testers who didn't do this: hair that turned orange and purple!
