Which of the following is considered a ground for disciplinary action?

Failure to wear clean garments is indeed considered a ground for disciplinary action within the cosmetology profession. Cleanliness and hygiene are critical standards in cosmetology, as they directly affect client safety and the overall image of the profession. Maintaining a professional appearance, including wearing clean garments, is essential to uphold the reputation of cosmetology services and to ensure a healthy environment for clients.

When cosmetologists fail to adhere to these cleanliness standards, it can lead not only to unsatisfactory service but also potentially to health risks for clients. Thus, adherence to dress codes that emphasize cleanliness is enforced as part of maintaining professional standards within the industry.

Unlicensed practice under supervision does not align with the legal requirements established for practicing cosmetology, but it is a separate issue regarding licensing rather than personal conduct. Excessive advertising, while subject to regulatory standards, typically relates more to fairness and competition in the market rather than personal hygiene. Similarly, failing to maintain a business website, while important for modern business practices, is not typically a ground for disciplinary action in relation to health and safety standards.
