Does it even work?

I am forced to question, do all of the things women do to impress men even work? I mean, the endless trips to the beauty shop, the continuous shopping to stay stylish, the make-up, the effort...all of it. Do men even notice or care about all of this?

I mean sure, I know it helps the initial attraction, but do you notice when we change the color of our polish? Or when we have tried a different hairstyle? I'm not saying every little thing, but does it take something hug for him to notice a change?
