Furthermore gelatin is not a homogenous substance, some brands will be smaller and some larger molecules. There will also be variation in the recipes used: which conditioner, how much of the additives, how thick or thin we spread the mix and so on. Some will be applying after an anionic shampoo, some after a cationic conditioner wash ....
