Well I grown my hair 4 times already, a little shorter than that length, but each time my family forces me to cut it off. I really mean force me, my mother cut my hair, and I was almost in tears because of it.
Last time it was growth from September to March; 7 months. The waiting part isn't hard for me, but the cutting is since I have to redo it each time.... then I lose it again. It's like my life will never start until my hair reaches a longer length.... it's almost depressing.
Yeah that "complete" look isn't possible until another year.
