Well, preening is one thing. Wild and unkempt is another. Real men like real women and real women tend to like men who keep their appearance tidy, you know, hair trimmed, clean, a comb once in a while.
Hair short and neat never goes out of style
Over my many years, I have probably tried about every look. But each time I go back to short hair and a clean shaven face, because it is easier to maintain. With short head hair and a clean face, you can be off grid for a week and sort yourself out in less than 15 minutes. Also, you look neutral, so what you wear determines what people see. So if you put on a Tux, you are well off. If you put on a t-shirt and grease stained jeans, you are ready for the oil changing pit.
