I've tried this a few times and i like the way it works, u don't have a hardness on your head and its soft and shiny. Is this a better way to keep your hair up? Does using conditioner more or less damaging to your hair?Using hair conditioner as a sub for hair gel?
I would think it would make your hair greasy looking. But I don't use gel so who knows.
