I do not think I will ever go back to a 1-length style. Don't like that triangular shape. I've had it long layered for 5 years and short layered(hairstylist mistake) for about half a year somewhere in between. On my thick hair with layers, I don't have to apply as much hairstyling products as I did with a one-length style.
