The fish look great. :D

Short hair generaly coinside with a clean cut look. When the hair covers the ears is when you start to have issues with appearance and cleanliness. Think of it this way. Long hair is a safety hazard in a production environment, pony tails could get caught in moving parts, long bangs could block your vision, both could be dangerous. In the food industry the less facial hair, head hair the better. Nobody wants to find a ahir in their food. In the medical field hair cna be a hygiene issue. The only time going bald or short hair is bad is if you have a bunch of tattoes. Then you have the appearance of a badass.

and one more fun fact, the military prefers short hair, the shorter the better. Pretty hard to look unprofessional with short hair and in full uniform. My chrome dome is Aunatural. Actually I have short hair too. 1/2" on top, and taper to zero at the ears. Blad guys look horrible in long hair. :D
