Which of the following is NOT a selling point of professional salon products?

The reason that larger container sizes are not considered a selling point of professional salon products is that the focus typically lies in the quality, effectiveness, and tailored benefits these products offer rather than their packaging size. Professional salon products are designed to address specific hair and skin needs, which speaks to their efficacy and expert formulation.

When salon professionals recommend these products, they rely on their knowledge and experience, which adds a level of trust and credibility to the recommendation. Additionally, the performance of professional products is generally superior due to their higher concentration of active ingredients, making them more effective for clients' specific conditions or concerns. Consequently, these aspects provide compelling reasons for clients to choose professional over generic or consumer products, whereas the size of the container does not inherently offer enhanced benefits or value.
