I have only had one unit with poorly tied knots, the rest of the units that shed were due to the quality of the hair.

Incidentally, the two worst shedding units had the most curl, and I had to lighten them a bit.

At first you might think that the lightening of the hair was the main culprit, but think about it.....when you bleach the knots, you are bleaching the weakest part of the hair, right where it bends, and if THAT doesn't cause shedding.....but then again maybe that IS the problem???

My last two full caps...when I pulled them out of the envelope i wanted to erect a shrine and worship them, because I IMMEDIATELY knew that the hair quality was absolutely superb. And guess what? No shedding, I mean ZERO. I was so disappointed that they had some other issues that rendered them pretty much unwearable, but the hair.....oh my god that hair.....

I showed BA the difference, and he said sometimes you get them one way, sometimes another, and that's pretty much been my experience.

My current order for four units is for straight hair. If that doesn't help to sufficiently solve the problem, I might even resort to ordering pure blonde hair and coloring the whole thing myself. At least that way I won't have to worry about knots either.

I am lucky in that I can order a high density with the full caps and let them shed down, but it would be nice to figure out a way to keep the hair in the base, cause I could probably get a year out of a unit by starting out with a higher density, if the hair didn't shed so badly.
