I’m generally attracted to women all over the place. Tall, short, blond, brunette, redhead, slim, curvy or flat, etc. I find some women attractive that hardly anybody else does, and I’m not attracted to a surprising number of women who most guys would find excruciatingly hot. But then I find some homely women homely and some hot women hot. With me there’s a very complex set of qualities that comes into play that make women attractive in different ways and for different reasons and results in my finding a wide variety of women attractive.
But as far as noticing hair, makeup, nails and so forth, I generally only do that when a woman is very attractive, and very well put together. And even then the feeling it triggers is usually more one of admiration than lust.
What does get under my skin and will keep me thinking of a woman for days afterward, even if she’s not particularly attractive, is an open, winning, cheerful smile, bright, sparkling eyes that look directly into mine, and the impression that she thinks I’m pretty hot stuff. Those three qualities will draw me to a woman much more quickly than will perfect hair, nails and makeup. And for a better reason too - her behavior makes me think she likes me, and that in turn makes me like her. And as a person, rather than a target.
But then just the other night, there was this excruciatingly cute little chick with a smokin’ hot physique at the grocery store, wearning very little makeup but dressed in tight pink flannel pajama-bottom style pants and Uggs boots and a fuzzy pink and white sweater …and there were bullseyes all over her. 
And then there’s the type who manages to convey interest and aloofness at the same time…
It’s…complicated.
But basically, men like it when you seem to genuinely like them. A winning smile, sparkling, interested eyes, and the impression you genuinely like the guy will get you a lot further than a lot of money spent on hair, makeup and nails will.
