Taking Multiple Medications — How Can I Pinpoint the Cause for My Female Hair Loss?

(female) I was put on Lorazepam, Topamax, and Wellbutrin. After over a year on Wellbutin, about3 months on Lorazepam, and about 2 months on Topamax my hair has begun to get very thin and frizzy. I thought it was falling out, I am not sure if it is that or breakage. I got a haircut, bought rogaine and am using Nioxin hair products. Which of these meds could have caused this and is there any way to pinpoint which one?

Pinpointing the one or two medications that are participating in your hair loss is very difficult. You need to go over this with your prescribing doctor. Have you been worked up for the various medical conditions that can cause female hair loss?
