Re: Porosity: what's up with that?
Vermelha - Castile soap bars are still made with lye. The only thing that castile means is that it was mostly (or completely, depending on how traditional the soapmaker is) olive oil and lye. After all, saponification, the reaction to create soap, is the reaction of an ester and a base.
The floating/sinking test seems like a really nice simple one to me. I know mine floats - virgin hair, straight, rarely heat-treated. I do use shampoo bars but I do remember hearing that they rarely work well on processed hair.
I wonder if silicones would temporarily decrease the porosity since it "seals" the cuticle?
Re: Porosity: what's up with that?
I actually have a bit of a theory about cones and porosity. My idea is that hair with cuticles that tend to be open (porous hair) is more likely to have cones get jammed under the cuticle and end up tangly/easy to damage/not shiny while using cones... whereas hair with a cuticle that tends to be closed (non-porous hair) is more likely to have cones wrap on top of the cuticle and keep hair shiny and easy to detangle.
Not sure how far my theory flies though :)

Hmm, sounds about right. Mind if I create a poll?

Go for it. I've always wondered if I was right :)
Re: Porosity: what's up with that?
My hair is naturally porous, but I just go with it I guess. I have stopped using chemicals but I still have a hard time getting moisture to stay in my hair.

That wasn't my experience at all, it was the exact opposite. When I went cone free is when I had the tangles and breakage from dryness.
Re: Porosity: what's up with that?
Interesting theory. That might explain why cones do wonderful things for the majority of my hair, but eventually give me sticky, tangly ends (where my hair is more porous due to age and some chemical damage). Looking forward to seeing the poll results.
From Buddaphlyy's post above, I would wonder if it makes a difference if your hair is naturally porous, or porous from damage. Perhaps cones settle evenly into naturally porous hair (working similarly to cones on non-porous hair) and build up unevenly in damaged hair (since the damaged areas are themselves very uneven and certain places would collect more buildup)...

Meh. My theories never pan out :)

You may be on to something but maybe it depends on the cone? Because when I was growing put my relaxer (therefore I had naturally porous roots and porous from damage on my ends) the only product that worked for my entire head was L'Oreal Nature's Therapy Unfrizz Smoothing Treatment which is chocked full of cones.
However, if I wasn't using this I would have to use one product for my roots and a totally different one for my ends to make my hair look alright.
Re: Porosity: what's up with that?
I wonder how good a gauge of porosity the float test is. I just tried it (I'm certain my ends are more porous than the rest of my hair) and what I expected to happen, did happen. Everything floated for a while, then I sort of poked the hair under several times along the length and everything came back to the surface quickly except the ends, which either stayed slightly submerged or floated back to the top more slowly (I did it with three different pieces of my hair).
Whether it's accurate or not, it's pretty relaxing to watch. *lol*
I'm going to leave one soaking for a while without touching it and see what happens...

Good point. There are so many types of cones with different solubilities...someone needs to do a proper scientific study! My brain hurts now! :D
