4. Hair In A Can
Quite literally does what it says on the tin. Treat your favourite balding friend or relative this Christmas by buying him a reminder of his diminishing virility, in aerosol form. Aside from the obvious problem of looking like a melting waxwork of yourself every time it rains, I do wonder how this thing works. Surely badly painting your scalp with foamy hair is going to work decreasingly well over the course of the day? Not to mention what happens if you're lucky enough to have somebody in your life to run their fingers through your hair. For the time being at least, the traditional response to premature balding of shaving your head and growing a little beard is probably still the best one.
