Can use minoxidil 10%, l arginine and tribulus terrestris together?

It is wise to find the cause for your hair loss and then get the proper hair treatment. Minoxidil could help to slow down hair loss but with not much growth. You can add any thing to it, but the end result is the same. 

But minoxidil will usually not turn a balding area into a hairy area, but might produce a bit a peach fuzz. You can add anything you want to it, and it may still work.
