Short. Tried growing it long back in the hippie era, but all I got was a tangled mess. My hair comes from Mom's side. Her family all had or have thick, unruly hair. Now my Dad's side had mostly thin hair. Even the women were practically bald. Dad was the only one who had a good head of hair, but when he went into the Army, it was shaved off. After he returned from the war, Mom thought he would grow his hair to where it was, but he didn't. Dad liked the DI haircut, so he kept it for the rest of his life.
My hair used to be brown, but today it's "salt and pepper" with far more "salt" than "pepper." I could color it and I tried to do so years ago when I first started turning gray. But my hair grows so fast, I'd be coloring it every 3 weeks No thanks. Have better things to spend time and money on.
