Has anyone else experienced loss while on vyvanse?

I (18F) have always had somewhat long, very very thick hair. I would get it coloured like most people do and never had any issues with hair loss because of the bleach. I also used to straighten my hair a lot and never had any heat damage or hair loss/breakage from the heat. At the beginning of 2023, I went fully blonde, my hair was fine though. Around that time I had just started taking new medication (70mg of Vyvanse), and I've been medicated for a long time so the loss of appetite side effect isn't anything new and doesn't bother me, but for some reason I feel like vyvanse made the loss of appetite worse. But I was struggling with an ED at the time, and wasn't eating. Mainly because I didn't have an appetite due to the medications and also because I was fat and wanted to do something about that. And from February 2023-July 2023, I had lost almost half my hair. Going from having thick long hair that would always snap hair ties all my life, to shorter very thin hair is weird and unpleasant. As soon as I noticed my hair was rapidly falling out, I dyed it back to dark brown (my natural hair colour) and started to try to take care of it. I've tried oils, serums, so much, but nothing works. It's been a year since, and my hair seems to have gotten somewhat worse.

In April 2024, I did a bit cut, because my ends were absolutely horrible and just needed to get cut off. That looked like it was helping for a while, but now it’s grown out and looks bad. I still have trouble eating, but it’s due to the loss of appetite from the medication, which has never been an issue in the past. Heat damage is something that is effecting my hair, although it’s not the main reason and concern, I know that if I just stop straightening my hair as much as I do then my hair will be somewhat better.

I’ve looked everywhere and can’t really seem to find someone with the same issue as me. I know that hair growth isn’t a “blink of an eye” kind of thing, but I just want my hair to grow back and to go back to being thick, even if I’m stuck with a bit thinner hair than before, I still just want my hair too look and feel healthy.

Is there anyone who has had the same problem as me? Or similar? And know how to fix it, ways to help or suggestions of supplements to take, serums to use, etc? Because I’ve tried everything, and it is the one thing that I have my mind set on fixing.

This could be just an issue where my body isn’t getting the nutrients it needs and that’s why I’m losing hair, but I had a thought that it could have something to do with the vyvanse and maybe someone out there has experienced something similar while also on vyvanse. Because don’t get me wrong, vyvanse has helped me so much, I love it and I’m so happy I’m medicated, but if it’s the reason my hair is falling out then I might need to change medications for the hundredth time.
