I done some consulting for Hindmarch recently on their hair bag, due to balding issues and we looked at a fixing spray. They will work to an extent, but unless something is done at the tanning stage its difficult.

can you send pictures?

I am SO glad I read this thread...I was just on the edge of dropping over 1K on a Coach calfhair legacy bag and would have probably lost my mind if the hair wore off. Disaster avoided!
