The word red in red hair covers a tremendously wide spectrum ranging from warm reddish brown to the quite unnatural hair color purple. Bleaching used to be the first step when coloring hair red. This is however rarely necessary with the newer coloring technologies
Without any doubt, right now the strongest hair color trend is red. Currently, the fashion world is particularly partial to blazing copper colors, which may just barely pass as natural. Red-haired models have never been so much in demand! (www.modelswithredhair.com).
You can be one of the trailblazers for this trend if you have shoulder-length hair. Red hair updos and streaked strands of soft wavy red hair are especially fashionable. Of course, there is no trend without a counter-trend.
