Which characteristic is NOT usually evaluated when assessing hair type?

When assessing hair type, the characteristic that is not typically evaluated is color. The primary focuses when determining hair type include texture, porosity, and density.

Texture refers to the thickness or width of the individual hair strands and can be classified as fine, medium, or coarse. This characteristic helps determine the overall look and manageability of the hair.

Porosity indicates how well hair can absorb and retain moisture, which is crucial for understanding how products will perform on a client's hair. Hair can be classified as low, medium, or high porosity based on its ability to hold moisture.

Density measures the number of hair strands on the scalp, which can affect styling choices and product selection. It refers to how closely the strands are packed together, impacting volume and overall appearance.

Color, however, is not a determinant of hair type but rather a separate characteristic that may be considered when selecting hair dye or treatments. It does not influence the structural properties of the hair itself, which are essential for assessing hair type and developing an effective hair care plan.
