What is the primary concern before selecting colors for a client?

The primary concern before selecting colors for a client is the texture and porosity of the hair. Understanding the hair's texture and porosity is crucial because these factors significantly influence how well the hair will absorb and retain color. The porosity of the hair refers to its ability to absorb moisture and color. Hair that is more porous may take color more quickly and can result in a more intense hue, while less porous hair may require different processes to achieve the desired color.

Texture is also important, as finer hair may respond differently to color treatments than thicker or coarser hair. Different hair types can lead to varying results in coloration and can also affect how long a color may last on the hair.

Taking these attributes into account ensures that the final result is effective, predictable, and aligned with the client’s desired outcome, leading to overall client satisfaction and hair health. Balancing these technical aspects with personal preferences, current fashion trends, and other factors is important but secondary to addressing the hair's inherent qualities.
