Just do it!

I'm of the belief that it is just hair. I've had mine super short, really long and everywhere in between. I've dyed it, bleached it, highlighted it, and now I'm completely natural and very white for someone who is 45 (though my underlying color is dark brown). I also wear it both ridiculously curly and super straight. Depends on my mood (and how much time I have).

I'm growing it out now but we'll see how long I can stand it. The 'in-between stage' can be rough. Right now, it's still a couple of inches from my shoulders, so I've got a long way to go before anyone can call it long even though it feels long to me. I've still got at least 6 months before I can even consider making any kind of 'tail' out of it!

Personally, I love the 'shock' of going from longer to super short. It's always such fun to me! I bet you'll get a huge kick out it once it's done.
