Which of the following describes a common condition affecting hair texture?

The condition that best describes a common impact on hair texture is a cowlick. A cowlick occurs when a section of hair grows in a direction different from the surrounding hair. This unique growth pattern can create a noticeable change in the texture and flow of the hair, often resulting in areas that may appear straighter, curlier, or stand out from the rest. It's particularly significant in styling because it can influence how other strands of hair lay or can be styled.

While baldness refers to hair loss rather than texture, and split ends denote damage that may affect overall appearance, they do not alter the inherent texture of the hair. Frizz, although it can affect the appearance of hair texture, is often a result of external factors such as humidity or dryness rather than a structural characteristic like a cowlick. Thus, cowlick is the most fitting choice when discussing alterations to hair texture itself.
