Nothing wrong with trying to appeal to others, but it is better to be honest about it. "Shave it off so it doesn't look as bad for most people and it doesn't affect your life as much" is a more honest advice than "it is all about confidence and value you give to others". Being real is part of the value you give to others.
There are a lot of things worse than losing your hair, but people who worry about it don't necessarily think they provide no value to others, and people who say they don't worry about it sometimes are the ones that worry so much more that they ended up changing their behaviour, routine and appearance (gym, beard, shaving, clothes, personality...) just to cope with the insecurity.
