I'm letting my hair grow out too and have been getting harassed about it. I was trying to tie it in a ponytail, but the sides are just about an inch short, so have had to use a pin on each side. I've seen quite a few guys with pony tails, but they tend to be older. You can have a real clean cut with a tight pony tail. My brother had one for years (though he had the sides shorter) but tucked it up under his hat at work and most people never new he had long hair - and he worked in a restaurant! The other day I did see a younger guy with real bushy hair and he actually was using a plastic hair band.
Recently I started using LA Colors Cashmere Curls gel. My hair is very curly when wet but dries wavy. This product keeps the curls, but they are softer than using hair spray. Several people have asked me if it is a perm or gel. I get ribbing from the guys, but I'm starting to like it, plus its easy to take care of. Just a little spritz of water, a little fluffing, and I'm ready to go.
