I've noticed the hair thinning when I brush my hair. Wish it wasn't so; I come from a family with receeding hairlines

.
I'm on 1200/day of TegXR and 450/day of Topa. (and Kepp as well)
The hair problems started with Topa. Teg I've been on since the start and didn't have the problem until I had TOpamax added in.
You are not alone in noticing this. I have a good amount in by brush every morning. It also appears the hair itself is now thinner compared to before I started on Topa. I take a multi vitamin on the sugestion of my doc BID with my meds. Not sure if it helps with the hair, but it helps based on blood tests when other body substances were lower then they should have been.
