white hairy tongue - lactose intolerance

Hello,
I have a variery of probelms, Lupus and Gluten intolrent being the main ones.  I recently went for a food intolerance test which showed that I also have a possible intolerance to Lactose.  I started using Lacofree milk instead of ordinary cows milk and noticed that the white hairy coating on my tongue has reduced and almost gone.  Although I have not cut lactose out of my diet completely and this may be why its not gone completely.
My question is - can being lactose intolerant be another cause of a white hairy tongue?

Try soy milk or almond milk if you are not allergic to those.  Cow's milk is probably causing all sorts of problems you don't realize.
