Alternatives to Selsun shampoo for itchy horses

[ElleSkywalkingintheair]

Have had great success with using Selsun shampoo for itchy horses this year, I've also used Nizoral on the less itchy ones which has helped with generic bum itching, but seems Selsun (the 2.5% stuff not the blue) is in very short supply and swapping hands for stupid prices (89.99 anyone?) So has anyone got any alternatives that work as well?

The Nizoral is good too, and easier to find but am not sure if is something better out there?

Many thanks folks
