No doubt at all that hair/makeup/etc are likely to be casualties in using this product... just like if that wife opts to take a motorcycle ride, wear a baseball hat for a while, strap on a diving mask for a swim, etc. Even a convertible can be a hair disaster if one takes a ride with wet hair.
And yet, men and women buy convertibles, ride motorcycles, wear baseball hats, dive, etc. If at the end of usage one needs perfect hair, don't use it. I see people opt to sleep on airplanes and head positions against airplane seats/walls can yield to hair disasters. I see people using headphones and that mussing up the hair by the end of the flight too. Yet such people still fly anyway and still opt to sleep or use headphones while flying.
Convertibles and motorcycles are far from the majority of transportation vehicles exactly because of convenience and comfort, if you are swimming well then your hair is wet...duh? My point is that the comfort factor will be another hurdle the VP's have to overcome, and for many consumers it will be an issue. It doesn't even have to be about hair and makeup, ie sweat, pressure marks on the face, discomfort from the weight, claustrophobia, inability to see the outside world (no pass through isn't as good as full vision), etc. A more glasses-like package would have gone a long way towards this.
