Epilepsy & Hair Loss

I am 21 year old (College student) with epilepsy since I was in 2nd grade. I've had hair loss for years now since my late middle school time. So it's been about 6~7 years since the hair loss started. At first, I didn't know what was the cause of it but I did nothing about it for years. When I showered, I would see hundreds of hair fall out. Nowadays, I changed the shampoo so I lose much less (about 100). I can see my scalp now a bit but not too bad for now. but I can also tell I lost a lot everywhere else in between, not just the scalp including getting an M shape forehead a bit. I noticed recently because I never put my hair up to show my forehead or cut my hair short not until I thought about trying it. I've been taking Zonisamide, valproate & lamotrigine for years now and increase the dose as I got older. Currently taking 450mg of Valproate & 125mg of Lamtrigine & 100mg of Zonisamide. I noticed a lot of people saying lamotrigine is giving them hair loss few months after they started & website says valproate gives hair loss (Lamotrgine was not mentioned for hair loss as one of the effects) I may do a surgery if possible to stop the seizures & taking the medications so I am currently in hospital for few days now testing where in the brain is causing it by watching me do seizures. I told the nurse today about the hair loss which I should have years ago when I visited the doctor but I did not know it was the side effect. The nurse said she'd change the medication after I'm out of the hospital for testing (whether I can do brain surgery or not) Website says that hair can grow back if the hair loss reason about because of medication/drug and is stopped. However I've been having hair loss for years due to medication & not few months like other who wrote posts. So I was wondering if it's still possible for my hair to grow back to normal or close to....
