What SE said. I found I couldn't buy my aloe in the regular skin care sections cause all of them were not pure and had alcohol as one of the main ingredients. I'd have to look in the natural foods sections.
Alcohol would definitely increase the dryness. With dry hair you probably only washed once a week before dreading...if you are doing more now that's making it worse too. Jojoba oil like SE said is a oil that is added to many natural skin and hair care products as a moisturizer...
Also maybe only soaping your scalp when washing? My hair is the opposite and gets oily....so never personally had this.
