This little section loop has made me nervous... I was touching my neck, and i felt something HARD [really hard], i thought that something was stuck on a section...But i found that this is a looped little thin section, but the "circle" [that in fact look like it is 2 looped circles] is REALLY HARD.
It's perfectly normal. Enjoy all those loops and stuff!
i had a little bit of that, its just that those hairs popped out there and theyre knotted themselves. like... its baisicly a mini dread sticking out of your dread haha. dont worry about it, itll work itself back in.
