When my hair was long, it was definitely high porosity. It would just soak everything up, felt rough when I ran my fingers up a strand, dried insanely fast, seemed to gobble up conditioner and product, met all the criteria for HP.

About 6 weeks ago, I big chopped (about 9" off total) and since then I've noticed subtle changes; it takes longer for my hair to dry, I now "drip" out of the shower (before, I could scrunch a few times and the drips were gone), have had less need for heavy products, use less product, no longer feels rough when i run my finger up a strand, etc etc.

I think my hair is now officially normal porosity. Just thought I'd share.
