You description of the gel haired metrosexual Kens matches perfectly the description of Patrick Batemen in "American Psycho". Here are some of Batemen's observations on himself:
"I live in the American Gardens Building on W. 81st Street on the 11th floor. My name is Patrick Bateman. I'm 27 years old. I believe in taking care of myself and a balanced diet and rigorous exercise routine. In the morning if my face is a little puffy I'll put on an ice pack while doing stomach crunches. I can do 1000 now. After I remove the ice pack I use a deep pore cleanser lotion. In the shower I use a water activated gel cleanser, then a honey almond body scrub, and on the face an exfoliating gel scrub. Then I apply an herb-mint facial mask which I leave on for 10 minutes while I prepare the rest of my routine. I always use an after shave lotion with little or no alcohol, because alcohol dries your face out and makes you look older. Then moisturizer, then an anti-aging eye balm followed by a final moisturizing protective lotion."
"I have all the characteristics of a human being: blood, flesh, skin, hair; but not a single, clear, identifiable emotion, except for greed and disgust."
"There is an idea of a Patrick Bateman; some kind of abstraction. But there is no real me: only an entity, something illusory. And though I can hide my cold gaze, and you can shake my hand and feel flesh gripping yours and maybe you can even sense our lifestyles are probably comparable... I simply am not there. "
