Newly diagnosed with ocular MG

I’m 72 a just diagnosed last November. Still navigating all the information out there. My only symptom is a drooping eyelid right now. My doctor tried IV/IG first. My BP wasn’t under control so we stopped that and started me on azathioprine twice a day. We’re going to try the IV/IG again soon since I’ve got BP under control. I have a really silly question, especially since there’s many things I know I’ll be dealing with going forward that will be be much more serious, and I feel silly asking this, but I haven’t been able to find an definitive answer to this question. Every 3 months I get my roots highlighted, is that something I should no longer do? (See, silly question). So far I haven’t noticed much if any hair loss, but I certainly don’t want to make it a problem. So glad to have a place to ask questions. Thank you all.
