Hi! I have problem with hair slipping with some of my fox skinns. When the hair slipps its often on its back close to the tail. Big chuncks falls off. This is how i do my skinns: 1 put the frosen skinn i 15 liters of cold water and add 2 dl salt. Its stay there for about 8-10 hours. 2 take out the skinn and starts fleshing it with a sharp spoon. 3 wash the skinn with some shampo in a bucket. Its often now i realize the hair loss! Does anybody knows whats the problem is?
