Is It Just Me...

Or when your hair is/ was around shoulder length, it was difficult to M&S (moisturize and seal) the back of your hair? I'm at shoulder length and when I M&S, I feel like I sort of miss the back of my hair, or only get the top layer of hair, not underneath if that makes any sense. I make a conscious effort to take extra care with the back, but I'm just wondering if M&S'ing the back of your hair gets easier as your hair gets longer?
