The back never seems to hold the curl or wave too well. I think I may just roll the back next time. I am always a bit disappointed when I spent so much time waiting in bantu knots only to have the back fall right back flat. Fortunately, the length of my hair is longer on the top, so those waves can cascade over the few unwilling locs in the back.
As far as the years of having my locs are concerned, I reflect back on my install, and I remember that my consultant, Imani, had just entered her seventh year with Sisterlocks. Today, she has had her locs for 12 years. They are still stunning, and time will tell where my locs will be in seven years.
