So, if things like oils, proteins, and panthenol (as it's used as a strand thickener) just sit on the hair instead on penetrating, is that just a coarse thing, or a porosity issue. Aloe and butters and fatty alchohols soak in well.
Fascinating topic, but it takes some time to wrap my head around it.
StruttsWife, that sounds like a fantastic color line. My colorist uses Wella, and he is pretty adamant that I try no to get my hair wet in the first 48 hours to prevent color loss. Something about the size of the red molecules needing time to fuse or penetrate or soemthing like that.
ETA: Straight oils just sit. Oils in a rich conditioner are OK.
Med/Coarse, porous curly.
