What might indicate that a client's hair is low in density?

The indication that a client's hair is low in density is represented by the clear visibility of the scalp through the hair. When hair density is low, it means there are fewer hair strands covering a specific area of the scalp, making the scalp more prominent and easier to see. This visibility directly correlates with the number of strands present—if there are fewer strands, the scalp will be more exposed, indicating low density.

Other factors, such as a thick and full-bodied appearance, would suggest high density, as would shiny and smooth hair, which typically indicates healthy and well-nourished strands. Resistant curl patterns generally refer to the texture of the hair rather than its density, implying that the hair may be more coarse or tightly curled, which does not necessarily correlate with the number of strands present. In contrast, the clear visibility through the hair serves as a clear visual sign of low density.
