I had a huge mop of hair when I started flying, mid-eighties, shaved on the sides and back with this "Sideshow Bob" mass of red ringlets all over my head, hanging over my face. It was great in the night clubs of Toronto, Montreal and Buffalo, NY but when I went job hunting, 100 hours and fresh commercial in my back pocket, I tucked the mass up into a baseball cap so I LOOKED like I had a shaved head. When someone finally hired me, I shaved the lot off and never looked back, but I KNOW I wouldn't have gotten hired if I looked like the wingnut I was.
30 years, 11,000 hours and numerous endorsements and countries and managing International operations and sim instructor and TRE and what-not....I'm almost respectable now, but you have to look respectable for people to even give you a chance.
I wouldn't have hired me!
