Groomer's Goop Shampoo

Groomer's Goop is a degreaser before it is a shampoo. It goes on a dry coat, works on grease, sap, tar or ground-in dirt, and only then do you add water to emulsify it.

That order is the whole trick, and it is the opposite of habit: wetting first seals the dirt into the hair and the product can no longer reach it. The range includes the original formula, the Snow White shampoo for light coats, and wipes for spot work.
