It really depends on the person, their hair thickness and curl type, and their own schedule. For me, getting layers cut into my hair and learning to blow dry with a diffuser was a god-send. I couldn't handle my immensely thick one-length hair. I can shower in the mornings now instead of having to shower by 7:30 at night or my hair still wouldn't be dry the next day. The layers also have to be done right too. Even after I had my hair cut short, my curls and waves were still bouncy because the layers were cut properly in the proper places.
