Short answer

Dissolve two tablespoons of citric acid powder in roughly one litre of hot, but not boiling, water. Soak the shower head in it for about an hour, or put a zip-lock bag of the solution over a fixed head and hold it with an elastic band. Wipe the head with a cloth and run water through it again.
