Which hair texture may tend to process slightly lighter than the intended level?

The correct answer indicates that coarse hair texture may tend to process slightly lighter than the intended level. This phenomenon is primarily due to the structure and porosity of coarse hair.

Coarse hair has a thicker diameter and often contains more layers of cuticle compared to finer textures. These additional layers can create a more robust barrier to color absorption, but once the dye penetrates, coarse hair can sometimes lift color more than expected because of its porosity and inherent characteristics. As a result, when color is applied, coarse hair can reflect and refract light differently, leading to the appearance of being a shade lighter than what was intended.

Moreover, the ability of coarse hair to absorb and hold moisture can also impact the final color result, making it critical for hairstylists to account for texture when formulating color. Careful adjustments in the mixing ratios or processing time may be necessary to achieve the desired color outcome for coarse hair.
