First let me say congratulations on the trike and I hope your rider/queen loves it as much as I do. I rode 2 wheels with Steve just to humor him, but never really liked it; now he can't leave without me! As to helmets, I don't think there is such a thing that doesn't mess up the hair. That is the downside to riding. We ride a lot and I've used silk scarves, do-rags, anything that might help make the hair easier to fix after we get off, but found nothing I was satisfied with. Using a "hairflair" visor I got to get an idea, I got a regular ball cap and sewed a wig on it. Now, when I take the helmet off, I slip on my "wigcap" and feel fine with going into stores, restaurants or to friend's houses, etc. Maybe this will help her. Lots of women wear just the ball caps, but I am not comfortable with it. We like to wear helmets not only for the safety factor, but because we can talk to each other and we don't like wind noise. Good luck with the helmet.
