WILD HAIR COLORS: While appearance is a form of self-expression for many, we must keep in mind that weâ€™re constantly under a microscope in the workplace. We donâ€™t want to do anything that will prevent us from being taken seriously. Unless you work in creative industries, such as beauty, fashion or art, very bright and unusual colors should be avoided. Itâ€™s best to stick to shades of brown, black, and blond that complement on your skin tone. Unusual hair colors are a distraction and will make it difficult for colleagues to look past the bright hue.
