Can taking Prenatal Vitamins with Ortho Tri-cyclen Lo Help Stabilize Hair Loss?

I've been on Ortho Tri-Cyclen for a year and been losing a good amount of hair ever since I started taking it. My doctor is switching me to Ortho Tri-Cyclen Lo, so I hope that might help. I've had many people (including one doctor) recommend taking prenatal vitamins, saying it'll help. It's to the point where I really don't want to be on birth control anymore. What do you guys think?
