Hair porosity is your hair’s ability to absorb and retain moisture. The three types of hair porosity are low porosity, medium porosity and high porosity. Having low porosity hair makes it harder for moisture to get into your hair cuticle and this tends to make your hair feel dry and harder to manage. Those with low porosity hair will benefit from deep conditioning treatments that help open their hair cuticles. Those with medium porosity hair usually require less maintenance. Their hair cuticles are less tightly bound and allow the perfect amount of moisture into their hair cuticle making their hair easier to style and retain moisture. Those with medium porosity hair, benefit from occasional deep conditioning treatments. High porosity hair allows plenty of moisture to penetrate the hair cuticle due to gaps between those cuticles. High porosity hair tends to easily become dry and absorb products quickly. Those with high porosity hair benefit from using leave-in conditioners and moisturizers.
How to test your hair porosity
- Fill a bowl with water.
- Take a strand of hair and place it in the bowl. (Make sure your hair is freshly washed and dried with no product in it for accurate results).
- Observe how fast your hair sinks.
What the results mean
- You have low porosity hair if: the hair strand floats at the top
and slowly sinks to the bottom.
- You have medium porosity hair if: the hair strand immediately
drops to the middle, then slowly sinks to the bottom.
- You have high porosity hair if: the hair strand sinks to the
