I'm at BSL curly and my goal is waist-length curly. I haven't had a trim in about a year, not even dusting (which I do myself). As long as my ends don't start splitting (fingers crossed) I won't touch them.

Someone above (I'm sorry, can't remember who!) said she wore it up 98% of the time -- that's exactly what I do, to protect the ends. I slather on tons of leave-in condish and pull it into a knob. I dont' take any multivitamins or supplements for hair growth and I save heat styling for special occasions.
Modified CG. You'll pry my 'cones from my cold dead fingers! Mixed waves, coarse, below shoulder length, dark brown. I hate my hair but I'm trying to learn to accept it.
