Hair density primarily determines the ____________.

Hair density refers to the number of individual hair strands per square inch on the scalp. This characteristic plays a crucial role in determining how hair is sectioned during cutting, styling, and coloring. When a stylist assesses hair density, they can make informed decisions about the size and number of subsections needed for various techniques. For instance, thicker or denser hair may require larger subsections to ensure an even cut or application of color, whereas thinner hair may need smaller subsections to avoid over-processing or achieve a more precise style.

Understanding hair density allows cosmetologists to tailor their approach to suit the client's hair type and desired outcome, ultimately leading to better results in their services.
