Which hair condition is characterized by high porosity?

High porosity in hair refers to a condition where the hair cuticles are raised or damaged, allowing moisture and products to easily enter and exit the hair shaft. This characteristic leads to several implications for hair texture and maintenance.

A rough texture is commonly associated with high porosity hair because the compromised cuticle structure can create a bumpy or uneven surface. The irregularities in the hair shaft can lead to an appearance that is less smooth, resulting in a rough feel when touched. People with high porosity hair often find it more difficult to maintain moisture and may notice frizz or a lack of shine, which further emphasizes the roughness of the texture.

Normal elasticity, water retention, and color absorption typically do not directly describe high porosity. Normal elasticity refers to the hair's ability to stretch and return to its original shape, which can vary independently from porosity. Water retention would pertain to how well hair retains moisture, which is often an issue in low porosity hair. Color absorption is related to how hair interacts with dyes; while high porosity hair can absorb color quickly, it can also lead to uneven results and fade more rapidly.

Therefore, the association of rough texture with high porosity is a significant indicator of the condition, making it
