ProGroom's 3 step de-shedding system starts with Furex Step 1: Cleanse. There is also and (available separately) 

The advanced, 3 point Furex system targets removal of stuck undercoat of double-coated breeds. This system eliminates the need to pre-groom heavy undercoated dogs before the bath. The product does the work for you. 

Step 1 is Cleanse. This shampoo deeply penetrates the coat. Cleansing while neutralising the ionic charge within the coat. Removing dirt, odour, excess sebum and oils. This step preps the coat for loose hair removal and is the start of the deshedding process.

"I’ve used the Furex products on Mika, my short coat Sibe and cannot believe the difference it has made, she’s usually a shocker for shedding even after a wash and blow dry - really really awesome products."  Sarah Hull - Whanganui, NZ
