I feel as if attraction is symmetry.
One of the things I learned in Post Graduate School (I went back to get my Masters Degree in Psychology) attraction is comprised a few key components.
A) Symmetry. The most attractive people in the world have a symmetrical look. One of the reasons a goatee or beard help is because it brings the focus of the eyes to where the hair is. If you trim your beard with angular lines that compliment your chin/jaw structure, then the focus of the eyes are on your lips, neck, and lower half of your face. When you shave your head completely, it looks planned, or groomed. It doesn't look unnatural or unruly. When things are patchy and not planned, your eyes directly go to the problem area.
B) Self confidence. Women since the cavemen times have looked for mates who they can procreate with that are strong. Strong can take on many meanings. Sex is biologically for pro-creation and attraction is natural selection. If you are unattractive, nature is saying "don't mate with this one." However, if you have self confidence, you are sending body language that says "I'm important. I like myself, others should like me too." It tricks them into being interested. Self conscious people give off the vibe, "I don't even like myself" therefore her brain is saying, "What is he hiding? Red flag! Something isn't right. He's hiding a flaw!" So she gets uncomfortable and wants to leave.
C) Personality. When I went through my depression between age 26-29, I wasn't fun to be around. People even said so. I didn't even like myself. When you have confidence, it bleeds over into your personality. Making a girl laugh, or showing you are intelligent are also 'mate-able' tools men have. It goes back to biology, girls want to procreate with men who are either 'Providers' (and that means intelligent or strong) and who will make good fathers/husbands (Nice, and makes them laugh) because women didn't want to have to raise a baby alone. This has nothing to do with getting a girl knocked up, it's just the way their brains are wired subconsciously and why they do or don't find you attractive.
Hair loss is considered unattractive because your brain has been taught 'age = can't get me pregnant" or "age = can't provide". So the reason a bald man with a beard, and in shape looks better is because it gives off the appearance that you can still provide. Look, you can't cure male pattern baldness. So if you really want to do something you can "control" then have the discipline to work out, get in shape, grow some facial hair to take the focus off your head and shave your balding scalp.
Just do what you have control over.
