Growing hair - a sore point

A beauty related comment for a change:
There is a TV  advertisement which asks if your underarms are sore after shaving (something ladies do).

It says (and also pictures) after 7 days of using their deodorant, underarms are smooth not sore.

Personal experience and many years of teaching anatomy and physiology, hair would have grown back by then.

Another groan: also on TV ads, women are shown smoothing cream on their legs - massaging in completely in the wrong direction.

Do they ever ask experts and users before creating adverts?
