Back in March or April i ordered stock super thin skins from Bysix, GEX Worldwide, Hairpiece Warehouse, MHE and.... another company I can't remember this second? Lol. And a couple of uts from GEX worlwide. The one from Bysix was the only one I kept because, although it had most of the same QC problems, the hair was at least in good condition.
Hairpiece Warehouse was a huge didappointment because they have been my go to for years and provided me the best hairpieces i've worn bar none, I will always stan for Kay and HPW but the two stocks I was sent in the spring after being waitlisted for months were not up to their usual standard. The base was extremely thick, there were way too many hairs per loop, no graduation and hair in poor condition. Pains me to say.
Gex worldwide - all the problems i mentioned except base thickness was okay.
Mhe - i was recommended by someone who said Curtis prides himself on customer service. I was a little apprehensive to begin with b/c i knew i'd be paying double for his youtube celebrity, but just wanted to try any new source. I sent him an email detailing the QC issues with the GEX pieces in particular (i didn't name the company), and asking specifically if he had something better. He then sold me a piece which was very obviously sourced from GEX!!! (absolutely identical save for the front contour shape, no plausible deniability whatsoever), except at double the cost. He denied it of course. I think i was in posession of it for 2 whole hours before i sent it back to him - i was really annoyed. So if any MHE customers on here want the same thing at half price, check it out seriously.
The Byix piece still had that issue of alternatng densities, and some very dark loops on a color #20. There were bald patches right behind the (non-graduated) hairline, and i ended up cutting off the entire front inch of the piece (section 1) and grafting a section i'd trimmed off the side of the base (section 2 + 4) just to make it wearable. That's the one i've been using since.
