It looks like you have a lot of hair. If you have a lot of hair, you can probably use a lot of product without it getting weighed down, especially if it's coarse.

My hair is Low Porosity, and I use plenty of curl creme and gel and one time forgot to rinse out conditioner and could hardly tell. So I don't think that's a good test.

If you really want to know, spring for the curl analysis! Cheap and informative.

I can tell mine is low porosity because:
It takes awhile to get wet
It takes a long time (6+ hours, up to 12) to dry if airdried from wet
It is Very Resistant to bleach, requiring 4 rounds with bleach and high volume peroxide to take out all the color, 6 hours of bleaching. Of course when I did bleach it, once it was done it was HIGH porosity.
It never gets split ends, even when grown for long periods of time.

Hope this helps.
