To understand low porosity, we need to understand porosity in general. Porosity refers to the ability of hair to absorb and retain moisture. The level of porosity determines how much water and other products can penetrate the hair and scalp. Dr. Karen Kaga, a California-based board-certified dermatologist, previously explained to us: The cuticle can be damaged by heat, over-handling, or chemicals, resulting in a change in the porosity of the hair. ”
Low porosity hair makes it difficult for water and other substances to penetrate the hair. Due to the tight cuticle, the product tends to stay on top of the hair, which can lead to dryness, breakage and tangling. is the best course of action.
To do this, grab a glass of water, collect a few strands and drop them into the water. Observe how your hair reacts to a small amount of water. If it floats on the surface, it is hair with low porosity. If it sinks, it is hair with high porosity. And if it’s in the middle of the glass, it likely has moderate to normal porosity.
