When selecting an appropriate shampoo for a client, what should be considered the key factor?

The key factor in selecting an appropriate shampoo for a client is the ingredients list. Understanding the ingredients allows a stylist to assess how the product will interact with the client's specific hair type, condition, and concerns. For instance, if a client has dry or damaged hair, a shampoo with moisturizing properties and nourishing ingredients would be essential. Conversely, if a client has oily hair, a clarifying shampoo that removes excess oil and buildup would be more suitable.

While brand popularity, price, and fragrance may influence a client's choice, they do not provide the same level of insight into how effective the shampoo will be for addressing the individual’s needs. Therefore, focusing on the ingredients ensures that the stylist can recommend the most beneficial product tailored to the client’s hair and scalp condition. This approach ultimately leads to better hair health and client satisfaction.
