Did you use the gel and mousse together?
You know what maybe this is baby hairs? I was feeling my hair back there and the finer ones are the ones that are tangly. Most of my hair has gone pretty thick strands but the baby hairs are all fine. Not sure how that works but those are the tangled nape ones.
Anyhoo, I hope you like TT, it's nice to find something inexpensive that works!
