The natural level of a client's hair color can be accurately determined by using the N scale on the hair color chart. The N scale is specifically designed to provide a standardized reference for assessing natural hair color levels, on a scale ranging typically from 1 (black) to 10 (lightest blonde). This scale allows the stylist to objectively categorize the hair color, helping to ensure consistent communication regarding color applications and outcomes.

Consulting the client may provide subjective insights about their hair history or preferences, while a visual inspection can give a stylist a general idea but lacks the precision offered by the N scale. Applying a temporary color does not help in determining the natural color, as it affects the hair's appearance without providing any fundamental information about the client's natural hair color. Therefore, the N scale is the most reliable method for assessing the natural level of hair color.
