What is a characteristic of hair with low porosity?

Hair with low porosity does not absorb color quickly due to its tightly sealed cuticles. Instead, it often requires more time and effort for color to penetrate, leading to a less effective dyeing process compared to hair types with higher porosity.

Color fading is more typical of hair with high porosity, where the cuticles are raised and allow for easier escape of color molecules. Low porosity hair tends to retain color longer because the tightly closed cuticles prevent color from leaking out easily.

Processing typically takes longer for low porosity hair, as the closed cuticles inhibit the penetration of chemicals, whether they are for coloring, treatments, or conditioning. As a result, achieving the desired effects often requires extended application times compared to hair that is more porous.
