The problem with trimming the lace all the way to the hairline, is that when you comb the hairline you tug on the very edge of were it's glued down vs. combing just the hair when you have excess lace in front of the hairline.

Plus once the lace starts shedding, hairs start to shed off as well.


Plus, there is always a few strands of hair that never want to lay right since they are knotted right on the edge of the lace.


Just some of the downsides. Not saying that I totally advise against trimming it all the way down, b/c I've done it myself more than a few times, but there are pros and cons to doing it.
