Karen question-Bad for hair??

Does anyone use or remember these hair combs from years past, they are small curved combs that you use to pull back a side section of your hair then it holds the hair up?
You sorta comb it back the flip it & shove it in your hair to hold it up. Well...these are the only items I can use right now to hold back my growing out layers and was wondering if they can tear your hair. Does anyone know???
Karen, do you know???

Thanks for any info!

Thanks!! Because, like I said, they are all I can use right now during this rough growing out period!!
