I used it for the first time about a week ago, my hair is extra dry as well, it feels almost like straw. I used the balancing moisturizer, and then I Deep conditioned with heat using SM deep treatment mask. I co-washed about 2 days later because it still felt dry and I moisturized and sealed. Still dry. My hair is extra frizzy as well, it's never felt like this. I hate to shampoo often, but I might do so this week to remove some of the residue and then Ill DC overnight. My hair does seem stronger though, I don't have as much breakage/shedding.
If I use it again, I won't use their balancing moisturizer and I may do as suggested above and either shampoo after application, or co-wash, then DC.
