You need to use more moisturizing products. There's nothing in your products to provide you with moisture your hair so desperately needs.
My stylist recommends avoiding mousse, as the propellent can be very drying.
I'd question the low porosity, too. Because low porosity hair is really smooth, it doesn't have the tendency to tangle like hair that is more porous. While I keep my hair shorter and get haircuts every six weeks, the only time my hair tangles is when I use an ingredient it doesn't like (castor or mineral oil.)
