Vitamins after RNY
Biotin isn't going to stop the hair loss and --as others have already mentioned -- it may cause growth of excess facial hair (which will be permanent), especially with such a high dose.
You can Google telogen effluvium to undrstand what causes the hair loss and why no vitamins or hair products are going to change it. You are going to lose what you are going to lose. Some lose more, some lose less... and a few lucky ones lose almost none. Just make sure you get adequate protein and vitamins so a deficiency in either one of those can amke teh hair loss worse.
