I’ve got very straight head hair, as well as straight armpit hair, but my arm and leg hairs are shaped roughly like parentheses, so still pretty straight, but not absolutely straight.
If I curl my hair, even with the heaviest duty hairspray, it’s straight again within a couple hours.
Wait now I’m curious, would it depend on your head hair curliness?
