Why is my hairline is lowering?

So yes, you read that right, my hairline is lowering, not receding.

Lately I've been finding random hairs growing out of my forehead about a quarter of an inch lower down my forehead than my hairline. I pluck them because they look weird and out of place. I have an average forehead that is balanced with my face proportions so not really wanting this change.

I'm not using any serums, no supplements or new treatments. We're in a hotel so I'm using their shampoo but it just seems like average, generic bottles in push pumps attached to the wall. I've been eating a lot of takeout since our house is under construction, so maybe the takeout is more nutritious than the food I usually cook? Even though I try to use lots of veggies and greens in my cooking.

Anyone have any idea what could be causing this? Some kind of hormone imbalance?
