I have crazy curly hair too. When it's short, I just run my hands over my hair and call it good. When it's in-between, I wear a buff. I pretty much need one to tame my hair just so that I could put a helmet on...never mind take the helmet off!

But, like others have said, if I'm going to be somewhere for awhile, I'll take my helmet off...otherwise, I just walk around with it on my head but the straps undone. This is what I do for grocery store trips. It's easier than carrying it!
