Yay! Good luck. If it doesn't work for you then come back and let the rest of the board take a stab at it. There are plenty of other ways to treat dry scalp/buildup I'm sure. Also try rubbing aloe or coconut oil into your scalp at night when it's especially irritated. You can always rinse and wash it out in the morning.
