A shampoo should be chosen based on what criterion?

Choosing a shampoo based on the condition of the client's hair and scalp is essential for effective hair care. The condition reflects various factors such as dryness, oiliness, scalp sensitivity, and specific hair types (like curly, straight, or color-treated hair). Each hair and scalp type requires tailored ingredients and formulations to address issues such as dandruff, moisture balance, or color protection. For example, a client with dry hair may benefit from a moisturizing shampoo, while someone with an oily scalp might need a clarifying shampoo to effectively remove excess oil.

While hair color, product availability, and cost may influence decisions, they do not directly address the individual needs and health of the client's hair and scalp as effectively as selecting a product based on these conditions. By focusing on the condition, stylists can recommend products that not only cleanse but also enhance the overall health and appearance of the hair, leading to a more satisfying outcome for the client.
