I did the strand test several times and found out that I have the three types of porosity, but my hair is mainly porous. (I also have the three textures as well.) Without a detangler, ladies with low porosity seem to have little to no tangles, while ladies with high porosity hair state their hair tangles easily. This is even after using a detangler. Ladies with normal porosity use a detangler or even water just once and their hair seems to stay detangled. HTH
