What must barbers ensure regarding their products before using them on clients?

Barbers have a responsibility to ensure that the products they use on clients are not expired and are stored properly. This is crucial for several reasons, primarily concerning the safety and health of the clients. Expired products can lose their efficacy and may even cause harmful reactions or infections. Additionally, improper storage of barbershop products can lead to contamination or degradation, further compromising their safety.

Understanding the significance of product integrity is essential for maintaining a professional standard in barbering. Clients trust barbers with their health and appearance, which is why it is vital for barbers to conduct proper checks on the conditions of their products. This practice not only protects clients but also reflects well on the barber's professionalism and adherence to health regulations.

Other considerations like promotion or brand diversity, while potentially beneficial for marketing, do not directly impact client safety and product effectiveness. Therefore, focusing on the condition and storage of products is paramount in a barber's daily practice.
