What type of member does not belong to the cosmetology board?

A hairdresser is not officially recognized as a specific member type on the cosmetology board. While hairdressers are skilled professionals in the field, the board comprises distinct roles designed to represent different aspects of the industry.

Barbers, cosmetologists, and public members all play significant parts in the governance and regulatory functions of the board. Barbers and cosmetologists bring professional perspectives from their specific fields, ensuring that regulations consider the practical realities of the profession. A public member contributes an outsider's viewpoint, which is essential for transparency and public interest.

In contrast, the term "hairdresser" is often used interchangeably with "cosmetologist," but it lacks the formal designation needed to qualify as a board member. Therefore, this distinguishes hairdressers from the officially recognized roles on the board, making this the correct answer.
