How does a cosmetologist determine the best shampoo for a client's hair?

To determine the best shampoo for a client's hair, a cosmetologist must assess the client's unique scalp and hair care needs. This involves considering factors such as the client's hair type (straight, wavy, curly), texture (fine, medium, coarse), and overall condition (dry, oily, damaged). It can also involve examining the scalp for issues like dryness, dandruff, or sensitivity.

By evaluating these individual characteristics, the cosmetologist can recommend a shampoo formulated specifically to address the client’s issues, whether that means adding moisture, reducing oiliness, enhancing shine, or providing scalp treatment. This personalized approach ensures the client receives the most effective product for their hair, enhancing the health and appearance of their locks, rather than relying on subjective preferences, trends, or brand fame.
