Which kills your hair more..straightening it or scrunching it?

which kills your hair more..straightening it or scrunching it? my hair is like so dead so I switched to scrunching it but I want to make sure that scrunching it is healthier?

scrunching it is like way healthier I think.
there's nothing really that can damage your hair.

I think that straighting it might be less healthy because it will make your hair really dry and dead in the long run. But don't scrunch it like ALL the time because I dont know if you have bangs but if you do the grease from the gell will get in your pores and cause you to have acne!! and that isn't very good!!! oh my the way want to b my friend?if so just click the add button if not whatever, well tude-a -loo!!
