The notion of "unprofessional" hair has been historically rooted in Eurocentric beauty standards, which often favor straight hair textures. The idea that curly hair is unprofessional stems from outdated and biased perceptions that associate it with a lack of neatness, control, and seriousness.
However, in recent years, there has been a growing movement towards challenging these narrow beauty standards and embracing diversity in hair textures. Curly hair is now widely recognized for its beauty, versatility, and uniqueness. It is important to note that the perception of curly hair as unprofessional is often subjective and based on personal biases rather than any objective criteria.
