What must all bottles and containers, other than original manufacturers', be?

All bottles and containers, other than those from the original manufacturers, must be properly labeled as to their contents. This requirement is essential for safety and regulatory compliance within the beauty and personal care industry. Proper labeling ensures that anyone using the products can identify the contents quickly, which is critical in preventing misuse or accidental mixing of substances that may be harmful.

Labeling also allows for proper handling and storage, minimizing the risk of spills or reactions. It provides information about the ingredients, potential allergens, and any necessary precautions, which is vital for client safety during manicures or other beauty treatments.

While options like being color-coded or eco-friendly might seem beneficial, they do not meet the necessary legal and safety requirements that labeling does. The emphasis is on clear communication of what the product is and how it should be used, making proper labeling the primary focus.
