I noticed something with dollyhair. Nothing bad, but I have some hair from many many years ago, and it's thicker than the new stuff. I did a fairly large order recently and have noticed the hair isn't as thick. Which for me is a good thing because you can style it easier. I don't know if anyone else has noticed this. BTW I think the old order is about 8 or 9 years prior. Give or take a year.
