Howdy, there! Lol
I live in a desert city in Cali, and I feel your pain on the lack of moisture in hair. My hair naturally really dry too on top of that, so I pretty much lost in the moist hair game.
So to help my keep moisture in I just keep a small spray bottle wiff water, condish and some oil mixed in whenever I go. It really helps a lot!
I never tried aloe vera before, so I can't help on that part.
