Which of the following must barbers avoid to remain licensed?

To maintain a valid barbering license, it is crucial to practice within the regulations set by the state. Practicing without a valid license is a direct violation of these regulations and can lead to serious consequences, including fines and the potential loss of one's ability to work as a barber.

Licensing ensures that barbers have met the necessary training, education, and health standards required to provide services safely and professionally. Therefore, to remain licensed, barbers must always operate with a current and valid license, adhering to the requirements laid out in their profession.

Engaging in practices without a valid license not only undermines the standards of the profession but can also pose risks to clients and compromise public health and safety.
