Thanks for the advice guys.
I spoke with Didi on the phone, she says the glue didn't dry properly. She noticed me sweating during the cut in, and I probably sweated a lot more on the way back in the subway.

I went from a having a forehead to a threehead(three fingers between eyebrows and hairline). I can definitely feel some of the system is positioned below my scalp skin on to my forehead skin when I raise my eyebrows.

My natural hairline also had a curve/arch as it went upwards towards the sides. This is more a straight line going across my skull. It's also likely this is a non graduated hairline since I specified that in the comments of the order. I feel like even though I'm 21, the non graduated hairline, it's location, and shape, is something that would look natural only on someone with perfect full dense temples. I've seen people with temple hair like that, even on people much older than me, and those are the only people who naturally have low, straight, squarish, very dense hairlines to accommodate those temples. I on the other hand have recession, graduation, lower density on my temples, so regardless of my age it just looks off. I miss my old hairline.

Didi said she is willing to make a template for me. I would probably be better off letting her get that crucial part of the system done right? And is keeping some of my natural hairline and placing the system behind it a worthwhile option for me to consider? My hairline wasn't even that recessed, it was just thinning out. I would definitely get a graduated hairline on the system for that. I imagine lace hidden behind natural hair would look the most natural right?
