Hi BipolarGirl, I've been on Depakote a long time but only for some months did I lose hair. So I guess it was the severe depression I was experiencing and not the Depakote after all. Anyway, it's not the first time I hear about hair loss with this med.
As BeyondtheRainbow said, there are good products against hair loss. I went to a very good hair stylist to get advice and she gave me a Kérastase product that you had to apply on hair before drying it. I don't know if you can find that in the US, though, but you can try. I had previously tried some supplements found at my apothecary and a product by René Furterer, but those didn't work as well as the Kérastase. I can look it up for you if you're interested, but it will have a French name as I was living in Luxembourg at the time.
