I use and like the HEHH conditioner. Some days my hair really likes it, other days it is just okay but it is a very good conditioner in my rotation.
I have come to the conclusion that you may be on the verge of coming to: That for my hair (porous too, BTW) and with my desert climate, my hair looks better with the milder cones than with the CG routine. I still use some CG conditioners, such as AOGPB, and I use Kirkland Hydrating as a cowash on my cowash days, but nowadays most of my stuff has the cones. I also find that my CG stuff works better when it's followed by the light cone leave-in. Example: the other day, killer hair day with Too Shea
and my Garnier Fructis leave-in over it. Too Shea
with a CG leave-in always left me with lots of frizz.
I like the bis-aminopropyl dimethicone (in the HEHH) and also the amodimethicone. This are "milder" silicones that you can get out with a low poo. They really help me with definition and cutting down on frizz. My hair does not
like the heavier cones such as cyclopentasiloxane or even plain ol' dimethicone. They are too gunky, plastic-y, and stringy in my hair.
So maybe the HEHH is indeed "that one product" for you! Just in case you'd like to try some other products that fit into the "light cone use" category, here are some others you might also consider:
new Pantene Curls Dry to Moisturized condish (bis-cone) I just got this and am testing it as a rinse out but also as a leave-in. So far, so good....
Pantene Curls Gel (PEG-12 Dimethicone, which is water soluble) This can be a little plastic-y but for the final touch up to smooth over everything before I head out the door, it is really good. Still testing for wet hair.
Garnier Fructis S&S Leave-In Conditioning Cream (a-cone)
Aussie conditioners also have the bis-cone but my hair doesn't like them as much.
