What indicates high hair porosity?

High hair porosity refers to the hair's ability to absorb and retain moisture. When hair has high porosity, it has gaps and holes in the cuticle layer, allowing for quick absorption of moisture. This means that it can soak up water or hair products rapidly, which is a characteristic of porous hair types.

Additionally, high porosity hair tends to dry quickly after being wet due to the same gaps that allow moisture to enter easily. This can lead to the hair becoming dry and brittle if not properly cared for, as it loses moisture just as fast as it absorbs it.

Thick hair texture does not directly indicate porosity; hair thickness is related more to the diameter of individual hair strands rather than the condition of the cuticle. Similarly, low susceptibility to damage would be indicative of healthier hair with a good moisture balance, rather than hair with high porosity, which is often more prone to damage due to its compromised cuticle structure.
