Ladies, are you ' Worth It ' ?

You know those adverts on the telly for L'oreal, where beautiful celebrity women advertise some hair product, suggesting women are somehow ' worth it '. Worth what ? Does it ever occur that the women advertising these products are beautiful, talented AND wealthy in their own right. Could it be they are saying THEY are worth it, but Sharon who works on the till at Tescos......? Lets be honest, I don't think the likes of Cheryl Cole and Penelope Cruz would give the average woman the time of day, do you ?
