Which board regulates cosmetology practices in California?

The California Board of Barbering and Cosmetology is the correct entity responsible for regulating cosmetology practices in California. This board oversees the licensing, education, and practice standards for cosmetologists, barbers, estheticians, and manicurists within the state. By enforcing laws and regulations, the board ensures that professionals in the field adhere to safety and hygiene standards, thereby protecting public health and welfare.

The other options refer to different entities that do not specifically address the regulation of cosmetology. While the California Board of Health deals with broader health issues across various sectors, it does not focus solely on cosmetology. The California Board of Cosmetology and Aesthetics may seem relevant, but it does not exist as a standalone entity—cosmetology and barbering are both regulated under the Board of Barbering and Cosmetology. Finally, the California State Licensing Board is a generic term and does not directly correlate with cosmetology regulations, as it encompasses various licensing boards across different professions.
