Hey all, just got my first piece installed yesterday. Really great matches color and I love the style, but I just can’t seem to get the hairline right. No matter what I do there’s a visible “line”, as attached. How would one get rid of this.

In the same vein, the stylist who dyed my piece ended up dying the knots as well so they’re super dark. Is there a way to fix this?

Ps, my skin is all cut up at the forehead from the alcohol swab
