Curly ends after Chinese bun, is that damaging?

[Venefica]

My favorite bun is a braided Chinese bun. I do not use bobby pins, I wrap the braids around whatever hairstick I am using that day, the ends I collect in a small elastic and wrap them up in in and put the little lump of elastic bound ends under my bun, I find it practical to do it like that.

When I take the bun out at night the ends are always very curly from having been wrapped in elastic. They get straight again rather quickly and I can not see any split ends or damage but I am starting to worry if the wrapping of the ends in the elastic might be damaging as they are so curly when I take them out. So is this safe to do or should I switch to bobby pins to keep my Chinese buns in place?

I find both elastics and bobby pins to be damaging (admittedly, my hair is rather fragile). I would recommend using hairpins instead if you are concerned about damage.

Ok thank you for the advice, but would not the metal in the pins be more damaging then the fabric of the elastic?
