I would just be CAUTIOUS...
When you wet your hair, your hair get engorged or filled with water...This causes your hair to stretch when wet and retract once dry... When I was reading
"The Science of Black" (a GREAT read) it called this hydral fatigued
Doing this constantly to your hair COULD lead to breakage....
My advice would be to find a really good spray moisturizer that is WATER based...
My hair can also get really dry between washes, so I use a moisturizer every night before I go to bed, and put on a satin cap to keep the moisturize in/protect my ends from breakage.
I mix my own into a spray bottle using:
* about full 2/3 water
* about 2 quarter size amounts of favorite conditioner (cone free), some times a little more depending on the size of the bottle/what conditioner
* a drop of honey ( a humectant that will help draw in more moisture/water to hair)
* 2 teaspoons of olive oil (any oil is fine)
Using this as a nightly moisturizer and curl refresher has been much easier for me than washing my hair everyday.
I'm not saying that washing you hair everyday is ALWAYS bad. Everyone has different hair/different results. But when my hair was damaged from relaxers/heat, I washed my hair everyday and it caused ME breakage. So from my experience washing will not necessarily always be good for your hair. Especially with longer hair, when the ends are more fragile.
FYI: I wash 3x a week
Hope this really LONG post helps you some
