No special winter helmet.
Down to -15-17 C, I use a headband and a helmet cover.
I have some special caps/balaclavas meant to go under a helmet. But I tend to sweat them down, and they interfere with fit more than the headband. Helmet cover works better IME.
Past that, I’d probably simply use my skiing helmet instead.
