POROSITY TEST

Take a couple of strands of CLEAN hair from your comb or brush and drop them into a glass of water ( room temperature). Let them sit for 2-4 minutes. If your hair floats, you have low porosity. If it sinks to the bottom of the glass, you have high porosity. If it stays in the middle you have normal porosity.

Avoid trying this test when your hair is dirty and full with products.
