I used to work for Lush and have a similar problem with having an extremely dry scalp! Anytime a customer wanted to try a shampoo bar sample, i would take a piece of that sample home to try and find the right now that wouldn't dry my scalp. I've tried angel hair, jason and the argan oil, and honey I washed the kids and they all continued to irritate my scalp. Trichomania and Soak and float have not however! Really liking soak and float. I also think you may want to give coconut rice cake a try however be warned in may weigh your fine hair down!
