Disappearing LENGTH over time?

I've had the same three  20-24"  bundles of Wags NC installed back to back since March/April 09. Last Summer I added a coarser/curlier of a bundle of 16"-20" to the area around my leave out since hair dye for my grays has made my hair notieceable coarser. I now have those same bundles installed on a u-part that I made about 5 months ago. I know that the wefts have thinned in the last 4 years and the hair is a lot curlier than it was when I 1st bought it but here lately it seems VERY short. My co-workers are asking me if I cut my hair. Out of curiousity, I JUST measured the installed wefts that have always hung the longest and stretched, one has never been cut because it was always on the bottom, it was the longest and it JUST measured only FOURTEEN inches.

I believe the ends are breaking off with wear and tear.

I'm wondering , when wefts shed over time ,does the longer hairs sewn onto the wefts shed 1st?   I ordered a bundle of 24-28" last week to add another layer of length to my wig but it seems that it may be considerably longer than what I have now.   I will measure them wet and stretched out when I make another wig /including the new hair, but it can't make THAT much of a difference. Again, I stretched the hair when measuring.   This is so weird to me, esp when I look at pics from a few years ago. I love my Wags NC (obviously, they've gotten almost a mortgage payment from me in the last 4 yrs),but this disappearing length doesn't make sense.   Anyone else experience this or are aware of this happening?

Yep I have had this issue too. Its due to shedding, and hair breaking off..

 I found out my favoirte Thread broke hairs after looking at the wefts with a magnifying Glass. Blond color mix will shorten your lengths also .
