Oh PLEASEEEEEEE...
This falls into the category of things that we wish were true but really aren't and is clickbait for anyone really interested in what attracts men.
Look, it isn't that complicated.
1. Be weight/height proportionate. Having an hourglass shape and showing that off is attractive. You can either dress to show off your body, or you can hide it in sweatshirts and sweatpants. Attractive women are fit, dress well and show off their features.
2. Have a good facial complexion. No matter what else, if you have a clear smooth face, men will find that immediately attractive. It doesn't matter if it means putting on so much foundation that you can't feel a pin poked into you face, but it needs to be smooth and preferably naturally toned. Smooth skin is immediately attractive.
3. Style your hair in an optimal manner. If you just wash dry and let your hair flap around, this is not attractive. Take the time to cut, and style your hair with some curls or whatever suits you. Many times, you can tell how attractive a girl will be just by looking at the back of her head. If that is in order, then most likely, the rest will be great as well since the hair is often the hardest part to get right.
4. It also appears that hair color plays a huge factor and that society deems that "blonde" is the most attractive hair color. This explains why blondes make up only 2% of the natural population, but 78% of the women who color their hair, change it to blonde and is probably the one single thing that a woman can do to make themselves significantly more attractive to most men. Unfortunately, this processes is super expensive and is like lighting your hair on fire.
Sorry to appear so "superficial", but I'm just calling out what I see and what is the "truth". I think this is the type of answer that most people are looking for but are not willing to admit. It isn't that complicated and provides a real answer to what turns mens head and causes them to say that a women is attractive versus the multitude of ordinary looking women. It isn't the politically correct answer that says that "looks don't matter" and that something like "health" is the key to attractiveness. The fact is that "looks" do matter for both men and women and by following these 4 suggestions, you can make yourself more attractive in a practical manner.
