I voted 2 weeks simply because I haven't been using what I think is my HG styling combination long enough to warrant voting six months. Also, I rarely get second day hair- I am lucky if it's still curling by evening- it's usually flattened out into a wave by then, but as it gets longer, that looks ok, too.
pink Boots with a little Aura hypo gel over it. I wish I hadn't waited so long to try Boots- I have had good hair with it since I started using it - no unplanned ponytails, even in the rain
and, of course, honey (when my wonderful child hasn't poured it on himself/ the floor)
