About the hair, I have this headcanon that, aside from it storing energy (as it seems to shine the more when the semblance is at its limit), for the Xiao Long its like a sign of pride.

Maybe even, since semblances have been said to be at least partially hereditary, in the Xiao Long family hair doesn't grow like for other people but it grows as they push the limit of their semblance. So, the most damage Yang becomes able to tolerate to turn it into power to punch back, the longer her hair grows.

It would give her getting pissed off at her hair being cut a whole new meaning.

And, yeah, I'm betting on Taiyang having really long ass hair.
