I would imagine women have a tougher time being confident. They're also more competitive with one another when it comes to looking great. You don't see a men talking about the suit a guy wore to an awards show.
The reason why there are so many commericals for them concering youth creams/lotions, hair color, eye lashes, lace wigs, numerous diets and weight loss programs, breast englarments, manicure/pedicures, "booty pop", botox, cellulite and spider vein removal.....etc (It's all because women buy this stuff).
The reason you don't see nearly the same amout of marketing geared towards men is because they don't care as much about their looks. Many believe if they are "successful" they can have the woman of their choice.
