I have gone to washing my hair less often, usually only once a week (no inbetween CO's or rinsing) since it's been colder and have experienced more tangles and drier hair despite oiling and wearing updos often. Could this be because I am not washing it as much I wonder? Anyone else noticed this? It is also getting longer and more toward waist so that could be adding to it too. Just curious about other's experiences. Thanks!
