If you weren't one of the less than 2% of the world's population and have naturally copper hair, there's some things to consider before you color your way there -
Reds have taken a hit for a long time for being soulless or ugly and that is likely because of the rarity of the color and the fact that most with red hair, have freaky pale skin and possibly tons of freckles.
My childhood freckles mostly disappeared with adolescence, a few remain. My back is an utter freckle farm.
Brunettes are often associated with being intelligent or exotic, self-assured, and forthright.
Red heads, however, are simply rarest. We cannot go unnoticed, have nothing to lose by being heard, say it like it is, and have a sassy sense of humor.
