What are three basic rules that apply to hair in order to maintain a professional appearance?

To maintain a professional appearance, hair should be clean and well-groomed, free from excessive product buildup or visible tangles. It should also be styled appropriately for the workplace, avoiding overly casual or extreme hairstyles that may distract from professionalism. Finally, hair color should be kept natural or subdued, ensuring it aligns with the company's culture and dress code standards.
