Giovanni TTTT low poo will help with the itching, but I never use it more than once a week. A dab of straight tea tree oil will help too. I can only use a tiny bit, because my hair is fine (even though it's crazy thick). Also, how are you massaging your scalp when rinsing out your products? That makes a HUGE difference for me.
