It took me about 3 1/2 years to get mine about eight inches below the shoulders, and another two years to reach mid-back length. Everyone's growth patterns are different; a former coworker had his hair go from a few inches to waistline length in two years. There are times when I miss it, but there many times when I don't miss it. I think my head actually sweats more with short hair than long, wtf.
If y'all look back MANY pages I am certain there are a few pics of me sporting the long locks and long beard.
Lookin good btw, Sabby!
Edit: I also highly agree with those that say you do not need long hair to like any metal music
