Even as the workforce continues to age, the answer to the question whether gray adds gravitas for those seeking to be hired or promoted or is a drawback that is best disguised depends on the circumstances. According Dave Carpener, writing for the Associated Press, experts suggest that Americans are ambivalent about gray hair in the workplace--with some companies eager to hire the gray-haired, while in some other areas there is extreme discrimination against older workers. There may also be sex-based differences, with women feeling less comfortable going gray in the workplace than men.
