Lol @ketchito, I am reading this at little bit after 6 am and ... it is a deep thought ...
Also, you need some media to let conditioning agents diffuse...it'd be like trying to swim in a pool with no water (not sure this is a good analogy, though 😅)
@Abdullah No worries! So, conditioning agents to go where they're supposed to go, need certain media (polar) to move and diffuse, and water is the perfect media...also, to keep both hair and conditioning agents in the right ionic state for deposition to occur. If your hair is dry, you won't have this available (except for the water from your product and the one that is bound to the most external layer of your hair, which is barely enough). An exception to this are anhydrous oils, which composition is obviously water free (natural oils, esters, silicones) and whose coating function requires no charge interaction.
@Abdullah By dry hair I was just referring to free water (there will always be some water within the cortex, but that's bound water, and won't act as solvent for actives). When hair loses lipids, it loses insulation, which means water exchange with the environment is more constant and dependent on factors like temperature.
